Reliability Constrained Unit Commitment Considering the Effect of DG and DR P...IJECEIAES
Due to increase in energy prices at peak periods and increase in fuel cost, involving Distributed Generation (DG) and consumption management by Demand Response (DR) will be unavoidable options for optimal system operations. Also, with high penetration of DGs and DR programs into power system operation, the reliability criterion is taken into account as one of the most important concerns of system operators in management of power system. In this paper, a Reliability Constrained Unit Commitment (RCUC) at presence of time-based DR program and DGs integrated with conventional units is proposed and executed to reach a reliable and economic operation. Designated cost function has been minimized considering reliability constraint in prevailing UC formulation. The UC scheduling is accomplished in short-term so that the reliability is maintained in acceptable level. Because of complex nature of RCUC problem and full AC load flow constraints, the hybrid algorithm included Simulated Annealing (SA) and Binary Particle Swarm Optimization (BPSO) has been proposed to optimize the problem. Numerical results demonstrate the effectiveness of the proposed method and considerable efficacy of the time-based DR program in reducing operational costs by implementing it on IEEE-RTS79.

Microgrid & renewable integration at burbank water & powerSchneider Electric
This presentation reviews Schneider Electric's collaboration avec Burbank Water and Power, a cutting-edge utility company in Burbank, California, to achieve challenging renewable energy requirements and provide reliable, safe, and affordable power to its customers using advanced technology solutions.
To prepare for increased renewable energy requirements, Burbank Water and Power sought a system to manage load, distributed energy resources, distributed storage systems, generation, and variable renewables in order to balance supply and demand and avoid undesirable voltage, power flow, and power quality problems. Burbank’s Integrated Automated Dispatch System (ADS) includes Schneider Electric’s advanced Power Control System (PCS) - for automatic generator control, load forecasting, and renewable forecasting - integrated with Schneider Electric’s OASyS SCADA and WeatherSentry system. The Integrated ADS will allow Burbank to co-optimize scheduling and dispatch of conventional supply resources, distributed generation, and demand-side resources, enable better control of inadvertent interchanges, and reduce reliance on external generation. Through the Integrated ADS, Burbank’s system operators will be able to manage the available system resources to optimize system reliability while achieving the most economic and sustainable energy supply portfolio.

On-grid PV Opportunities in University Campuses: A case study at Nazarbayev U...Luis Ram Rojas-Sol
The universities around the world are taking every day a more decisive role in fighting global warming. Indeed,
many campuses are not only teaching established and disrupting clean energy technologies, but also are practicing
their lectures. For example, the University of Arizona, USA, leads the campuses with 28 MW of installed On-Grid
PV systems (http://www.aashe.org/resources/campus-solar-photovoltaic-installations/top10/). Furthermore,
campuses of emerging universities, as Nazarbayev University (NU), located in Astana, Kazakhstan, which is
developing with the firm aim to become a leader world class research university in the heart of Eurasia, are taking
this commitment as well. Additionally, being Kazakhstan the host of EXPO-2017 which has the motto: ¨Future
Energy¨, it is natural to evaluate if NU campus would be a good candidate to support and exhibit, with demonstrated
technical and economic advantages, its own On-Grid PV in-campus system. Therefore, in this investigation, a
feasibility study of installing PV panels on the rooftop of School of Engineering at NU is carried out. A 24 kWp rooftop
PV installation with a 14.7% capacity factor, capable to export 31 MWh of electricity to the grid per year, is assumed
to be the system for the purpose of this analysis. The financial analysis has a horizon of 20-year lifetime and 25%
debt ratio financed at 15% interest over 20 years. Selection of appropriate equipment and calculation of financial
outcomes under three different scenarios or policy options are presented. The policies or scenarios corresponded
to having or not government grants (GG) and having attractive Feed-in-Tariff (FIT) rates in order to determine their
financial benefits. The GG scenario was stretched up to consider 30% of the total project cost and FIT was varied
from current offered FIT rate by KEGOC (Kazakhstan utility company) of 36,410 KZT/MWh to a more attractive rate
of 70,000 KZT/MWh. Results demonstrate that current scenario of FIT is marginally favorable (IRR on Equity: 15.1%,
Benefit-Cost Ratio: 1.37, Equity Payback: 8.8 years), while the 30% of incentives on top of current FIT moderatedly
improves the benefits of the project (IRR on Equity: 20.9%, Benefit-Cost Ratio: 1.47, Equity Payback: 7.2 years).
Nevertheless, upgrading current FIT to 70,000 KZT/MWh, even without incentives, proved to be enough to
dramatically improve the outcome of the project for investors (IRR-Equity > 28%, Equity Payback of 5 years and
Benefit-Cost ratio > 3.6), demonstrating that with a subtle change in policies, Nazarbayev University as many other
campuses in the country, may easily justify the investment in their On-Grid PV systems and therefore, become part
of the “green” universities in the world with direct contribution to tackle climate change.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? 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!

Main conclusions
• The Hadoop cluster is by nature resilient and coped with nodes failure
• The processing times can be greatly reduced over traditional architecture
• There is a high need for customization
• The choice of the tool within the Hadoop ecosystem depends highly on the type of calculations/use-case to be made

12. EDP Inovação 12
After choosing the model we identified a set of explanatory variables and tested the model over
National Demand
Explanatory variables:
• Year, month, day
• Day of week
• Public holiday
• Season (Spring, Summer, Autumn, Winter)
• Daylight save time (TRUE, FALSE)
• Time of year
• Time of day (48 1/2 hour intervals)
• Temperature From NOAA website
Dataset:
• Half-hourly electricity measurements
• National demand (mainland Portugal)
• From 2006 to 2011 – Data for calibration
• From 2012 to 2014 – Data for test
High temperature ~ demand peak
(2013 - 4th highest heat wave since 1981)
Low temperature ~ demand peak
(2012 European cold wave due Siberian High)
13. EDP Inovação 13
In order to increase the model’s accuracy and looking at the major residuals, we started a trial
and error process to identify the main causes that would decrease the model errors

But there were still some issues with the forecast. After special days like Christmas the model
shouldn’t use the load values of the previous day to forecast
This lead to a new approach of using a weighted majority algorithm
15. EDP Inovação 15
In this approach we had several algorithms that were trained to certain conditions and the
model automatically choose the one that minimized the error for each period

5. Conclusions
19. EDP Inovação 19
The PREDIS project and other use-cases revealed a series of limitations that currently exist in the
IT systems
• How can we expand analytics knowledge in business areas?
• How can we achieve massive data extractions without impacting the performance of existing
operational systems?
• How can we avoid a proliferation of interfaces each one with a specific function?
• How can we interpret the data that exists in current IT systems?
• How to “democratize” the access to data so that multi source analytics can be developed?
• How to “stream” the data needed to address some of the use-cases identified ?
These requirements were important to develop a new approach of IT systems
and lead to a specific analysis of the current Analytics architecture
20. EDP Inovação 20
Traditionally a utility has analytic solutions based on a silo oriented BI architecture that isn’t
prepared to deal with high volumes of data with structured and unstructured information

Nowadays operational systems create more data every day in the 3V’s that characterize Big Data
(Volume, Variety, Velocity). A conventional infrastructure cannot handle operational activities and
advanced analytics in due time.
Big Data comes as an option that allows data ingestion and advanced analytics of high
volumes of data oriented to one of the 3V’s (Volume, Variety, Velocity),
keeping operational systems with their normal activities.

Findings & Conclusions
• Big Data Analytics is a continuous learning process and a cultural change. To overcome the lack of
knowledge in this subject a Advanced Analytics and Machine Learning training in R is being
lectured in EDP. Additionally a SAS Miner training is scheduled for the 2nd trimester of 2017
• Access to overloaded source systems’ data can be difficult. CDC (change data capture) extractors
seem the best way to extract data from the source systems and have the data available near real
time to analytics users
• The development of a Data Lake will decrease the number of interfaces between operational
systems
• The Unified Data Model, where information is organized and cataloged, allows a unique vision of
all available data (and can support the “single source of truth”). But we need Data Governance!
• Support of a experienced IT partner for several of the activities involved is essential to avoid
major pitfalls and to help detail architecture “sweet spots” for each use-case
