Open Compute has had a revolutionary impact on data center design ,offering many simplicity and cost saving benefits. To become more mainstream, we believe critical questions need to be answered about the implications of OCP on the upstream power infrastructure. Can data centers still achieve Tier 3 redundancy? How do I support traditional and OCP loads in the same data center? This presentation will address these and other questions, and propose a series of simplified architectures to support OCP. We will discuss redundancy, availability, and flexibility implications, as well as present a cost analysis. Schneider Electric embraces the spirit of OCP by openly sharing this analysis and making these simplified reference designs freely available

This document summarizes a study on distributed energy resources (DER). It discusses how increased DER is changing power systems and potential reliability issues. DER provides alternatives to large central plants but can impact transmission systems. The document recommends:
1) Collecting and sharing DER location, type, and performance data across transmission and distribution systems to support modeling.
2) Modeling DER in bulk power system studies if significant impacts are expected based on location and output.
3) Avoiding netting of DER with load and instead aggregating or explicitly modeling DER based on penetration levels.
The document analyzes the technical and economic viability of solar photovoltaics (PV) and energy storage systems to provide both economic and resiliency benefits at three critical infrastructure sites in New York City. The analysis models four scenarios: 1) Resilient PV sized for economic savings without considering resiliency needs, 2) Resilient PV sized to meet resiliency needs, 3) A hybrid system of resilient PV and generator sized to meet resiliency needs, and 4) A generator only system sized to meet resiliency needs. The results show that resilient PV can be economically viable and provide resiliency benefits for NYC critical infrastructure, with the exact savings depending on site-specific factors. Hybrid systems generally
The Advanced Distribution Management System – ADMS – brings together distribution management system (DMS), supervisory control and data acquisition (SCADA) and outage management system (OMS) technologies , along with control room applications, on one, secure platform with a single user interface. With this comprehensive mission critical solution, the electric utility can monitor, analyze and control the distribution network to improve the level and quality of service.
At its core is the network model representing the as-operated state and based on the as-built state defined by the geographic information system (GIS). A load flow algorithm responds quickly to data sourced from throughout the network to analyze the balanced, unbalanced and dynamically changing network in real time. Users across the network – operators, dispatchers, management, planning engineers and others – have consistent visualization of model results in geographic, schematic and single-line diagram views. State estimation validates viewed data and estimates non-telemetered points to achieve a complete network representation.
With this accurate network model and a portfolio of robust functionalities, the utility is empowered with continuous, real-time analysis of the operational state of the network that enables self-healing capabilities. Demand can be managed through reduction of technical losses; by forecasting near-term load and applying volt/VAR control for peak shaving; and by securely integrating and managing distributed energy resources, including energy storage, to flatten the daily load curve. These and other options enabled by ADMS are key to managing demand in the face of increasing energy usage, surging energy costs and network infrastructure instability due to aging.
The ADMS represents the evolution of control room technology that will help utilities mobilize to meet increasing consumer demand and environmental obligations and reap many of the benefits all stakeholders expect from their smart grid investments.

Case studies show global companies cutting annual energy bills by millions through centralized energy procurement and performance benchmarking across their portfolios.
International Standards: The Challenges for an Interoperable Smart GridSchneider Electric
Building an electric energy Smart Grid involves proper interfacing between existing devices, applications and systems – all likely sourced from many different vendors. The resulting interoperability allows valuable advantages, such as the ability to use distribution system demand response (DSDR) to improve the efficiency of delivered power. Interoperability enables automated switching sequences, for system ‘self-healing’ and improved reliability, along with effective integration of distributed renewable and non-renewable resources that can enable peak shaving. Interoperability also is vital for assimilating emerging automation technologies that will enable the utility to realize these benefits in the future – and protect public and private sector technology investments.
The International Electrotechnical Commission (IEC) defines international standards, recognized globally, that characterize interoperability and security of electrical, electronic and related technologies. These standards are created to assure interoperability within all the major power system objects in an electrical utility enterprise and allow mission critical distribution functions to take advantage of real-time data in a secure manner. The IEC standards also enable reliable exchange of data among utilities and across power pools.
The U.S. National Institute of Standards and Technology (NIST) is incorporating IEC standards, and developing new or revised standards, to be applied in its development of a Smart Grid as a national energy goal. This standards framework aims to eliminate the implementation of technologies that might become obsolete prematurely or be implemented without necessary security measures – and help utilities make the infrastructure decisions that reduce cost and energy loss, improve network reliability and embrace technology innovation.

About this presentation:
This presentation gives a brief overview of the product management process milestones. This document was created based on over 7 years of experience working in product management roles at both start-up companies and corporations.
This document provides an introduction and overview of the book "Project Management: A Managerial Approach" by Jack R. Meredith and Samuel J. Mantel. It discusses the growing use of project management in business and organizations. It positions the book as taking a managerial perspective on project management rather than a technical or specialized focus. The introduction explains that the book is intended to teach students how to manage projects from a holistic viewpoint.
The document discusses physical distribution and distribution channels. It defines physical distribution as moving tangible products through distribution channels. Physical distribution management involves activities like order processing, inventory control, inventory location and warehousing, materials handling, and transportation. When designing marketing channels, marketers consider factors like setting distribution objectives, specifying distribution tasks, developing alternative channel structures, evaluating relevant variables, and selecting channel members. Channel structure dimensions include the number of levels, intensity at various levels, and types of intermediaries. Variables affecting channel structure are market variables, product variables, company variables, intermediary variables, and environmental/behavioral variables. The key is developing a channel structure that aligns with objectives and considers all relevant factors.
Evaluation of Utility Advanced Distribution Management System (ADMS) and Prot...Power System Operation
Practical and cost-effective communications solutions are needed to enable control of the growing number of integrated distributed energy resources (DERs) and grid-edge local aggregator devices such as home energy management systems. Each year, the total installed photovoltaic (PV) system capacity increases by an estimated 5 GW, over half of which is interconnected to the distribution system.1 PV’s increasing penetration—already accounting for the bulk of DER capacity—underscores the need to enable and manage its continued integration on the distribution system.2 Much previous work has shown that advanced distribution management systems (ADMS), which are effectively integration platforms for various grid control and visibility applications, can help enable the integration of higher levels of PV while also improving the overall performance and efficiency of the distribution circuit. Greater connectivity and controllability of utility- and customer-owned equipment increases the level of DER integration and overall circuit performance.3 The required performance of the enabling communications system, however, has been less thoroughly studied and is often greatly oversimplified in ADMS performance analysis. The availability of new technologies such as distributed sensors, two-way secure communications, advanced software for data management, and intelligent and autonomous controllers is driving the identification of communications standards and general requirements,4 but the link between the communications system and the expected performance of a utility-implemented control system such as an ADMS or other communications-reliant protective function requires further investigation.

This document summarizes a research paper that assesses the impact of electric vehicles (EVs) and distribution static synchronous compensator (D-STATCOM) controllers on electric distribution networks. It finds that EVs can negatively impact power quality through increased voltage drops and imbalance factors. The document also reviews past literature on distributing distributed generation and flexible AC transmission system devices like D-STATCOM in distribution systems. It identifies gaps in assessing unbalanced and mixed distribution systems with these technologies and calls for more probabilistic studies of their combined impacts with variable loads.
A new simplified approach for optimum allocation of a distributed generationIAEME Publication
The document describes a new methodology for optimal placement and sizing of distributed generation (DG) units in distribution networks. It involves:
1) Calculating the Tail End Nodes Voltage Deviation Index (TENVDI) by placing DG at each node to determine the optimal location with the minimum TENVDI.
2) Determining the optimal size of DG placed at the optimal location by varying the DG size and finding the size that results in minimum complex power losses.
3) The methodology is tested on IEEE 33-bus and 69-bus test systems in MATLAB. The results show reductions in losses and improvements in voltage profiles with optimal DG placement and sizing.
The document discusses energy profiling and management in a smart microgrid system.

Design and Control Issues of Microgrids : A SurveyIRJET Journal
This document summarizes key issues in the design and control of microgrids. It begins by defining microgrids and outlining their basic design considerations, which include suitable sizing and positioning of distributed energy resources. The document then discusses design aspects like optimal component selection and control strategies. It describes the hierarchical control approach for microgrids, with primary control focusing on voltage/frequency regulation, secondary on deviation mitigation, and tertiary on economic optimization. Finally, it outlines some major issues in microgrid design and control, specifically islanding detection challenges and non-detection zones, where changes in voltage and frequency may not trigger detection.
Neural computing is now one of the most promising technologies in all fields of engineering,
resulting in the development of a number of Artificial Neural Networks (ANN). Double circuit transmission lines
are being employed in the distribution of power to consumers and have become more widespread than single
transmission line, as they increase the electric power transmission capacity and the reliability of an electrical
system. Losses along transmission lines occur due to faults. Possible faults on the transmission line were
predicted using Artificial Neutral Network. In this work, the simulation of fault on a 132kV double circuit
transmission lines using MATLAB was undertaken. Parameters considered during the simulation were the input
of the network which is the fault current value at each fault location while the output of the network is the fault
location. The efficiency of the neural network was tested and verified. This approach provided satisfactory
results with accuracy of 95% or higher.

FAULT DETECTION SCHEME OF 5 BUS BY ANN AND ANFISIRJET Journal
This document proposes a fault detection scheme for a 5 bus system using artificial neural networks (ANN) and adaptive neuro-fuzzy inference systems (ANFIS). The scheme involves using discrete wavelet transform (DWT) to preprocess current and voltage measurements and extract statistical features. These features are then input into three ANNs/ANFIS models for fault classification, identification of fault phase, and detection of fault location. Simulation results on the 5 bus system demonstrate the effectiveness of the proposed scheme in accurately detecting fault type, phase and location in a fast and robust manner compared to previous methods.

IRJET- Analysis of Demand Side Management of Distribution SystemsIRJET Journal
This document analyzes demand side management techniques in distribution systems using an IEEE 33 bus test system in DigSILent PowerFactory software. It implements different demand side management approaches like incorporating distributed energy sources, load shifting, and valley filling. The distributed energy sources used are distributed generators and batteries. Load shifting is done by shifting different percentages of load to off-peak hours. Valley filling is analyzed for different cases. The results of these demand side management techniques are compared to the base IEEE 33 bus system in terms of improvements to voltage profile and losses. The effectiveness of each technique is evaluated based on the losses.
Target Response Electrical usage Profile Clustering using Big DataIRJET Journal
This document discusses using clustering algorithms to analyze large datasets from smart meters to identify patterns in electricity usage. It proposes a new method for clustering micro-clusters that uses a density graph to explicitly represent the density of data points between micro-clusters. This allows the micro-clusters to be re-clustered into a smaller number of final clusters. The algorithm involves constructing a minimum spanning tree from the density graph, partitioning it into trees representing clusters, and selecting representative features from each micro-cluster. This clustering-based feature subset selection aims to improve the efficiency and accuracy of load profiling and short-term load forecasting using big data from smart meters.

Alt. GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using ...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

General typical observations Gabriël (his share of papers)
Quality of papers seems to increase (Just a few bad papers).
- Topics vary from very practical isolated single case studies to very broad theoretical
discussions
- The intermediate ones are most interesting, applying tough theory to harsh practice.
Very few papers from multiple countries
- Meaning for international cooperation?
Dutch papers rarely refer to related or even similar neighbors' utilities activities
- Meaning for national cooperation?
Methodology trends continue
- More awareness about limitations of “conventional” ways of planning or operation.
- More attention to newer methods, including optimization, probabilistics, …
- No new standard or tool emerging already yet

1330 THE EFFECTIVENESS OF USING IEC61660 FOR CHARACTERISING SHORT-CIRCUIT
CURRENTS OF FUTURE LOW VOLTAGE DC DISTRIBUTION NETWORKS
Abdoulah EMHEMED Graeme Burt, UK
This paper is about the effectiveness of using IEC61660 for short-circuit current
characterisation of LVDC
And it is also about
- Potential benefits the LVDC offers for future power systems
- challenges brought by the LVDC technology for understanding fault behaviour and effective protection
systems.
Conclusions are: by comparing IEC61660-based calculation and PSCAD/EMTDC simulation, it
shows:
- IEC61660 is effective for faults at the converter terminal, except the IEC decay time for fault current is
significant faster than that from the PSCAD simulation.
- For remote faults, IEC61660 still gives correct steady-state fault current, but less accurate
(underestimating the severity) for characterising the capacitor discharging currents.
- LVDC system designed based on IEC61660 will experience problem with, component rating and fault
detection.
- The reason for the error, IEC61660 was developed for small DC auxiliary installations, not for large
networks.

This paper is about creating a platform to determine the optimzation of charging

implemented. Based on defined defined power limits and power generation a
charging algorithm was developed that enables allocation of charging power to
individual vehicles as a function of their state-of-charge.
It is concluded that the algorithm provided decreases the number of vehicles which

Two Scenarios based on location: closer to and further from the distribution transformer.
Modelling aspects:
- Monte Carlo approach is used.
- Time-series behaviour of loads and PV generation: 5-min resolution models for domestic
load and PV generation
- Load profile and PV profile are linked
Impact indices:
- Percentage of consumers with voltage problems

This paper focusses on the impact of electric driving on the electricity grid. With this
purpose measured loads in MV/LV distribution substations and load profiles from
EVs are combined. This enables an evaluation of the moment, the place and at
what level of charging point penetration the grid starts to saturate.
It is concluded that with active control from the DSO, it is possible to double the
number of charging poles on office locations, provided the EVs stay connected to
the charging point for 8 hours and charge for 4 hours.
In the analyzed residential areas, at least a doubling of the number of charging

Enexis has adapted its load forecasting method for HV/MV-transformers to
incorporate the influence of distributed generation.
AMR measurement data, total generation and total demand in an MV-grid can be
determined and separate forecasted, with a certain correlation between demand
and generation for different types of DG. Forecasts can be merged into a single
forecast of transformer loading.
Based on the correlation a minimum DG infeed can be determined, as a
percentage of installed generation capacity.
The forecast can be used in the regular

ANALYSIS
ARRITT, DUGAN, USA
Load allocations for distribution system analysis is one area in system modelling
where simple, generalized assumptions are commonly made by distribution
planners for lack of better data. In this paper three techniques (Transformer kVA
allocation, Monthly Usage Allocation, Class Loadshape Allocations) for load
allocation are analyzed and compared to the case with actual AMI (advanced
metering infrastructure) data for all customers. Using the load allocation, network
analyses have been performed.
It is concluded that AMI will provide distribution planners with greatly improved
predictions of actual system performance. Other methods not only under-report
overloads but also mis-report overloads. For network losses the Monthly Usage
Allocation gives similar results to AMI.

Conclusions are
- A comprehensive system engineering approach is needed for LVDC technology to ensure

1330 THE EFFECTIVENESS OF USING IEC61660 FOR CHARACTERISING SHORT-CIRCUIT
CURRENTS OF FUTURE LOW VOLTAGE DC DISTRIBUTION NETWORKS
Abdoulah EMHEMED Graeme Burt, UK
This paper is about the effectiveness of using IEC61660 for short-circuit current
characterisation of LVDC
And it is also about
- Potential benefits the LVDC offers for future power systems
- challenges brought by the LVDC technology for understanding fault behaviour and effective protection
systems.
Conclusions are: by comparing IEC61660-based calculation and PSCAD/EMTDC simulation, it
shows:
- IEC61660 is effective for faults at the converter terminal, except the IEC decay time for fault current is
significant faster than that from the PSCAD simulation.
- For remote faults, IEC61660 still gives correct steady-state fault current, but less accurate
(underestimating the severity) for characterising the capacitor discharging currents.
- LVDC system designed based on IEC61660 will experience problem with, component rating and fault
detection.
- The reason for the error, IEC61660 was developed for small DC auxiliary installations, not for large
networks.

Antti MUTANEN Pertti JÄRVENTAUSTA Matti KÄRENLAMPI Pentti JUUTI, Finland
This paper describes two alternative methods for calculating AMR based load profiles. Both
load profiling methods models the load temperature dependency and random variation
separately.
- The first method used AMR measurements to update the existing customer class load
profiles but kept the customer classification unchanged
- The second method used k-means clustering to update both the load profiles and customer
classification.
- Individual load profiles were formed for large and abnormally behaving customers.
Hourly measurements from two Finnish distribution companies have been used.
Innovations: inclusion of seasonal temperature dependency
Conclusion: The new AMR based load profiles were better than the original load profiles.
When forecasting future loads, the cluster profiles had the best average fit. No significant
improvement in peak load forecasting capability was detected when compared with the
updated load profiles.
Challenge remains for peak load forecasting of the customer and distribution transformer.

Innovations: the idea to predict power continuity indicators taking into account
various aspect such as weather conditions, past investment, condition and/or aging
of network components is very challenging.
Conclusions: The DSO could improve its insight about the impact of each driver in
their results. The impact of a management strategic option on the results can be
determimed to a certain extent.

CONSIDERATION OF LOSS AND RELIABILITY USING PSO
MIRI LARIMI, HAGHIFAM, IRAN
This paper proposes a multi-objective optimization to determine the optimal size and
location of distributed generation in the distribution network to minimize load supply
cost and enhance reliability improvement.
The losses and marginal loss costs are minimized. Particle swarm optimization is
used to solve the optimization problem.
It is concluded that the optimal buses for DG placement are further away from the
main bus.

1035 Impact of load and DER management on microgrid reliability
Talari, Haghifam, IRAN
This paper shows that LV microgrids can be run in islanded or connected mode, and
presents a way of economic optimization of running the microgrid.
Additionally, it takes reliability considerations into account as well.
The study is based on a hypothetical microgrid, and it is unclear how this relates to
reality.
Conclusion is that the performance of the microgrid can be improved by using load
management and switching between islanded and connected mode.

REN. GEN. IN DISTRIBUTION NETWORKS
Antoine MINAUD, Christophe GAUDIN, ERDF - FRANCE
This paper is about analyzing the cost of DG/RES integration(mainly PV and wind)
in the MV and LV networks
And it is about studying innovative solutions (reactive power control, active power
control) to reduce these costs
Innovations are local reactive power control / curtailment to reduce costs of
integration distributed generation
Conclusions are:
- Local reactive power control should gain 20-40% on MV reinforcement costs and 10-20% on
LV reinforcement costs
- Curtailment of active power should gain 30% on MV reinforcement costs and 10-20% on LV
reinforcement costs

1428 ASSESSMENT OF THE INVESTMENT EFFORT IN HV AND MV
NETWORKS TO REDUCE ENERGY LOSSES
José Carvalho Martins José Ribeiro da Silva Carlos Alberto Santos Francisco Cravo Branco J. Nuno Fidalgo Manuel A.
Matos Mário J. Couto , Portugal
This paper describes a methodology to select the most adequate reinforcement investments
in HV and MV network lines, based on a cost/benefit analysis.
The cost are related to reinforcement costs, the benefit to revenues related to avoided loss.
Key part in the methodology is the classification of MV networks according to the loss
reduction potential.
Then, MV networks having the larges loss reduction potential are selected for a more
detailed analysis.
Innovations: none
Conclusions: reinforcement investments in HV networks causes a larger global loss
reduction than those in MV networks.
