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.
Electric utilities are preparing for the multitude of challenges facing the industry — limited generation to supply increasing energy demand, growing regulatory and customer pressure for increased reliability and reduced carbon emissions, adoption of distributed renewable generation and energy storage, and the inevitability of both an aging workforce and infrastructure.
In a rather short period of time, these challenges have converged, and in doing so, have exposed the need for a comprehensive distribution network monitoring, analysis, and control system.
Utilities that are proactive — building business cases and deploying scalable solutions now — will be best prepared to meet the challenges of today and the future. To assist the industry in achieving their strategic Smart Grid goals, Schneider Electric proudly offers its Advanced Distribution Management
System (ADMS).

The building of Internet data centers (IDCs) is a growing industry that is pushing the limits of electric power and reliability requirements. As utilities must decide whether it is worth the cost to build new infrastructure to keep up with the present demand, facility operators are looking at power distribution designs that will improve efficiency and allow them to continue to expand their operations.
Unleashing the limitless possibilities of electricity in technological applications requires proper caution and care. Handling vast amounts of energy—in any form—comes with significant hazards. When energy is released in an undesired way, the results can be devastating. One only needs to consider some manifestations of unwanted energy release in nature such as lightning strikes or earthquakes, to realize that handling energy requires due care.
Fortunately, the manifestation of energy in the form of electricity can be controlled—and thus can be made safe—relatively easily. Since its discovery, numerous methods and systems have been developed for harnessing electricity. This has enabled the benefits of electricity in everyday use and avoided its hazards.
The first section presents the most important and common hazards associated with the use of electricity, along with some basic concepts on hazard, risk, and risk reduction.
The second section gives an overview of common and standard design solutions, with a focus on the safety aspects of the particular techniques cited.

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.

Multilevel inverter fed induction motor driveseSAT Journals
Abstract Induction motor drive is used in almost all industries including oil and gas sectors, production plants and process industries. Speed control of induction motor is a major concern. The proposed technology implements a better speed control for induction motor drives using a multilevel inverter. The switching sequences are generated by optimized pre-calculated angles for controlling induction motor. And also with the use of a multi-level inverter there is lower distortion of output voltages and Total Harmonic Distortion (THD) of machine currents under steady state operating conditions can be minimized. THD can be further reduced by optimizing the switching angles. This technology can be extended to higher levels of output voltages by using an n state multilevel inverter. In this paper, a seven level multilevel inverter is proposed, its simulation is done in MATLAB/Simulink and the results were verified by experimenting on a hardware prototype. This could be extended to higher levels of voltage waveform and can be used in photovoltaics. A multilevel inverter could be a better choice as a dc-dc converter in solar power circuits. Keywords: Multilevel inverter, optimal pulse with modulation, total harmonic d1istortion.

More Electric:
Our world is becoming More Electric. Almost everything we interact with today is either already electric or becoming electric. Think about it. From the time you start your day in the morning to the time you finish your day – your home, your car, your work, your devices, your entertainment – almost everything is electric. Imagine the energy needed to power this. Electricity consumption will increase by 80% in next 25 years
More Connected: Our lives are also becoming more connected. The Internet has already transformed the way we live, work and play. Now the Connected Things is going to take this to a brand new level. 50 billion things connected in the next 5 years.
More Distributed: With such a widespread electrification and connectivity, energy models need rethinking as well. Which is why the generation of power needs to be closer to users. Distributed Energy is rapidly evolving globally. This is positive energy – renewable. In 2014 , Renewables overtook fossil fuels in investment value, with $295bn invested in renewables compared to $289bn invested in fossil fuels. And it is getting cheaper to do this.
More Efficient: When our world is more electric, more connected and more distributed, new opportunities emerge and allows us to tap into even more efficiency – in industrial processes, in the energy value chain, in buildings, in transportation, in the global supply chain and even in the comfort and peace-of-mind of our homes.

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).

Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. The Advanced Distribution Management System
Executive summary
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.

4. The Advanced Distribution Management System
Introduction
Electric utilities are preparing for the multitude of challenges facing the industry
— limited generation to supply increasing energy demand, growing regulatory
and customer pressure for increased reliability and reduced carbon emissions,
adoption of distributed renewable generation and energy storage, and the
inevitability of both an aging workforce and aging infrastructure.
In a rather short period of time, these challenges have converged, and in doing so,
have exposed the need for a comprehensive mission critical solution to monitor,
analyze, and control the distribution network.
This paper will provide an overview of the Advanced Distribution Management
System (ADMS), including its diverse portfolio of functionality and a host of
benefits for the distribution network owner and the energy consumer.

7. The Advanced Distribution Management System
The foundation of the ADMS
At the core of the ADMS is the ability to precisely
define the network model, and to process an
unbalanced load flow algorithm based on that model
with telemetered data taken from the network.
• he network model
T
The ADMS must be able to represent all aspects
of the distribution network, including a variety of
conductor types, transformers, switches (both
manual and motorized), fuses, and other permanent
and temporary devices used in distribution system
operations. The model represents the
as-operated state of the network typically based on
the as-built state as maintained by a Geographic
Information System (GIS).
• he dynamic data
T
To enable accuracy of the ADMS load flow
algorithm, it requires data telemetered from the
distribution network. That data is generally made
available through supervisory control and data
acquisition (SCADA) systems, telemetry, where
available, through AMI, and via OMS.
The amount of data to be telemetered and stored
is significant and changes frequently, suggesting
that high performance data management is critical
for quick and efficient analysis by the ADMS. This
data provides a variety of information (e.g. voltage,
current) and device status (e.g. open/closed) to
enable the load flow algorithm to provide more
reliable results.
• The unbalanced load flow algorithm
The ADMS must have a very fast load flow
algorithm that can solve unbalanced distribution
networks based on ever-changing data
telemetered from the field including single phase
operations such as on laterals, fuses, and
underground network sections.

Visualization of ADMS results
With a complex network model, significant quantities
of data (both telemetered and calculated) and the
wide variety of ADMS users (operators, dispatchers,
management, planning engineers, etc.), providing
visualization of ADMS results is an important
consideration. An ADMS should be able to display
network data in a geographic view, a schematic
view, and in single-line diagrams. Further, the end-
user should be able to easily manage the level of
information displayed in these views.
Individual utilities have developed different means
to view their network information over time, and the
ADMS must be flexible enough to support the format
desired by the utility.

State estimation — ensuring the
accuracy of ADMS results
Generically, state estimate can be defined as “a
branch of probability and statistics concerned with
deriving information about properties of random
variables, stochastic processes, and systems based
on observed samples.” In power networks, state
estimation validates observable data and estimates all
non-telemetered points in order to derive a compete
network representation.
The quality of data collected from various points
on the distribution network is typically imperfect.
Problems in devices or in the telecommunications
networks associated with those devices suggest that
prior to conducting an advanced analysis, the data
must be pre-processed to eliminate bad data points,
estimate non-telemetered points, and resolve any
issues with “time skew” for unsynchronized telemetry
systems.
Distribution State Estimation is much more than

the network state with the highest possible precision
as it is the basis for all advanced functions and

Operations planning and analysis
One of the primary uses for the ADMS is the real-time
analysis that enables optimization of the distribution
network. The ADMS continually runs real-time
analysis, identifying problems and suggesting
approaches to better balance load, suggest switching
to minimize losses, and identify other potential and
real problems, as well as likely solutions.
The ADMS enables utilities to reduce energy waste
on their distribution networks through a more

reconfiguration and network optimization — to
minimize those losses.

Demand Management
Demand management is a key capability that
drives utilities to Smart Grid programs and to the
implementation of ADMS software. Many options
can be exercised to manage demand in the face
of increasing energy usage, surging energy costs,
and network instability. The ADMS understands that
there are multiple approaches to demand response,
and the software can direct the implementation of
demand response options that are created by Smart

Distributed energy
The Smart Grid was initially intended to support
the addition of environmentally-renewable energy
resources to the distribution network, including wind,
solar, biomass, and others. However, managing a
distribution network with hundreds or thousands of
potential energy sources requires an ADMS.
The ADMS can help maintain the balance needed
to reliably operate a diverse supply environment in
the face of dynamic changes in demand and in the
topology of the distribution network.
As distributed generation becomes more prominent,
distribution networks may tend to become small
“islands” of energy that can operate while connected
to the rest of the distribution network. They may
also operate independently as a “micro-grid” in a
disconnected manner. The ADMS can manage
the network through these operating approaches,
optimizing it for losses, reliability, or cost of operation,
while maintaining a secure distribution network.

Conclusion
The ADMS is an indispensable tool of the Smart Grid era. Starting with the
foundation of a fast, unbalanced load flow engine and the ability to validate data
via state estimation, the ADMS provides complete functionality to help utilities
optimize their distribution networks. The software also provides dispatchers,
engineers, and others who operate and manage the network with easy network
visualization.
The ADMS includes significant functionality to manage outages and perform
FLISR operations. It also has the tools to support Volt/VAR Optimization, which
enables Distribution System Demand Management (DSDM): a form of demand
response that operates utility controlled devices with no impact to customers.
The technology supports distributed energy, enabling the utility to grow and
accommodate the renewable generation expected of the Smart Grid era, while
optimizing the network for reliable service.
Lastly, the ADMS represents the evolution of control room technology by
merging DMS, OMS, and SCADA technologies into one comprehensive network
management solution. As part of a Smart Grid strategy, it can help utilities
transition into next-generation energy providers.
