ISGT 2016 Industry session will take part during main conference, from Monday, October 10 till Wednesday, October 12, in the afternoon. Information on the industry session and instructors is shown below.
Experiences from ELECTRA REX – A Researcher Exchange Programme for Smart Grids
Speaker: Professor Graeme Burt, University of Strathclyde
Description: This special session will provide an opportunity for delegates to hear papers presented by a number of participants in Call 2 and Call 3 of the ELECTRA REX researcher exchange programme. The researchers will each share the outcomes from their exchange experience at a prestigious smart grid laboratory, and be supported by an internationally co-authored paper. ELECTRA IRP (http://www.electrairp.eu/) is a European FP7 project focussed on new decentralised control approaches to the real time control of voltage and frequency in the future smart grid, and is underpinned by the “Web of Cells” concept. Consequently the session will also serve to inform delegates of exciting new developments in smart grid controller development, SGAM formalisation, simulation and testing of real time controls. This initiative is supported by the European Commission under FP7, and is related to the international coordination efforts of the European Energy Research Alliance Joint Programme in Smart Grids.
Delegates will also receive an update on the current round of Calls inviting applicants for smart grid researcher exchanges, open to industry and research participants.
This special session will be the second in the series of ELECTRA REX Workshops, with the first one forming a successful special session at EDST’15, Vienna, Austria. Six exchange researchers participating in the first REX Call presented their papers at this session, which attracted nearly 40 delegates.
Challenges and Opportunities of Big Data in Power Quality Analysis
Speaker: Jan Meyer, Technische Universitaet Dresden, Germany; Jovica Milanovic, The University of Manchester, UK; Ivo Novakovic, TECTRA d.o.o. Zagreb, Croatia; Peter Bergant, Elektro Ljubljana, Slovenia; Adnan Bosovic, JP Elektroprivreda BiH, Bosnia and Herzegovina
Developments in enabling technology (monitoring equipment, communication technology, data storage and processing) have made it possible to monitor Power Quality on a large scale. Introduction of new load types like Electric Vehicles, the proliferation of storage applications and the continuous increase of inverter-based generation place additional pressure on network operators to monitor, report and control various aspects of network performance. Consequently the number of installed Power Quality monitors and the amount of available Power Quality data is growing vastly. These data contain a lot of valuable information about the behaviour of Power Quality, but at the same time the management and analysis of these big data becomes a more and more complex challenge for the network operators. Particular due to the lack of sophisticated and automatic analysis tools up to now only a very limited amount of the available information is used.
This panel provides an overview of the major challenges of big data in Power Quality analysis applications. It addresses general aspects of designing larger Power Quality measurement campaigns and the basic requirements on instruments and sensors. Beside real experiences of a distribution network operator, novel ideas on indices for Power Quality benchmarking and the use of the data for including Power Quality aspects in network planning are discussed.
Peer-to-peer trading, control and communication in microgrids
Speakers: Prof. Geert Deconinck, KU Leuven, Belgium; Prof. Ari Pouttu, Oulu University, Finland; Prof. Jianzhong Wu, Cardiff University, UK; Prof. Furong Li, Bath University, UK; Jesus Alonso-Zarate, Centre Tecnològic de Telecomunicacions de Catalunya (CTTC)
Moderator: prof. Geert Deconinck, KU Leuven, Belgium
Description: Next generation microgrids will require a decentralized approach, in addition to or replacing centralized coordination. Peer-to-peer technology provides interesting opportunities for this, from the level of trading and business models, all the way down to control approaches and communication technology.
The European H2020 project P2P-SmartTest (LCE-2014-3) employs peer-to-peer approaches to ensure the integration of demand side flexibility and the optimum operation of distributed energy resources within the smart distribution network while maintaining second-to-second power balance and the quality and security of the supply. It investigates and demonstrates how a smarter electricity distribution system emerges with innovative business models.
This half-a-day workshop (i.e. two sessions) on 10, 11 or 12 October 2016 – as a part of ISGT 2016 – presents the key concepts and demonstrators of P2P-SmarTest.
It will consist of 4 presentations.
- Decentralized approaches in smart grids and positioning of P2P-SmarTest (Prof. Ari Pouttu, Oulu University, Finland). Due to the vast amount of information from controllable devices and actors in smart grids, a paradigm shift towards decentralized approaches is required. The P2P-SmarTest project will be presented with its solutions to tackle these challenges. The different demonstration sites in Spain, Belgium and Great Britain will be discussed.
- Peer-to-peer concepts for trading among microgrids (Prof. Furong Li, Bath University, UK). A model will be discussed to trade flexibility from users and aggregators between microgrids. Innovative business models and relations to the energy market are presented.
- Peer-to-peer concepts for control in and among microgrids (Prof. Jianzhong Wu, Cardiff University, UK). Distributed control in microgrids allows to implement the trading agreements among smart grid actors, while ensuring that the grid remains within its technical limitations (e.g. voltage limits). Several algorithms and results will be presented, indicating how decentralized control complements and improves central control paradigms.
- “Device-to-device Communications for Smart Grids: Status Quo and Road Ahead (Dr. Jesus Alonso-Zarate, CCTC, Spain). Wireless communication, partly based on 5G data exchange, allows for predictable and high bandwidth telecommunication among smart grid actors. Based on a case study, the underlying technology will be discussed.
The presentations will be followed by a lively, moderated discussion between the speakers and the audience.
Increasing the penetration of renewable energy sources
Speakers: Bart Meersman, Ghent University; Phuong Nguyen, Eindhoven University of Technology; Andraž Žertek, Korona; Andrej F. Gubina, University of Ljubljana
Description: The INCREASE project focuses on the development of the solutions which address the question “How to increase the integration of renewable power in the distribution network”. The intermittent nature of power feed-in of the DRES and due to fact that network wasn’t designed for mass integration of DRES, results in poor network performance in case of high DRES production. Over-voltages, congestions and impact on protection devices are only few of the issues and challenges of the Distribution System Operators.
The INCREASE solutions consist of advanced control of DRES generation, OLTC control and implementation of demand response using controllable loads. INCREASE control schemes are used to cope with voltage issues and congestions in the distribution network. A cornerstone of the INCREASE solutions is an advanced PV inverter with integrated droop control. Using droop, the inverter can curtail the PV output in case of high voltage at the connection point of the inverter. That way over-voltages are avoided, in addition the green energy feed-in is maintained at certain level and not completely shut-down as in case of classic PV inverters.
The proposed technical session will present the multi layered control concept developed and implemented in INCREASE project. Demonstration results both from laboratory and from field will be shown. The proposal is for a technical session time slot (1,5h) on Tuesday (11.10.2016) afternoon.
The session will be divided into four 20-minute presentation as follows:
- INCREASE project overview (Bart Meersman)
- Technology and Control algorithm concept (Phuong Nguyen)
- Demonstration and Evaluation of results (Andraž Žertek)
- Recommendations (Andrej F. Gubina)
The presentations will firstly set-up the project’s landscape, describe current issues in the low voltage grid, and define how INCREASE projects can solve them from different viewpoint.
Later we will describe the proposed control algorithms in detail. By general principle INCREASE project offers multi-layered control approach, namely Local control, Overlaying control and Scheduling control. First is based on a combination of a voltage based droop control and a voltage unbalance mitigation strategy. Since the R/X ratio in the low voltage distribution grid is high, the reactive power will not be efficient for the voltage control. Therefore, active power is used for the voltage control.
This local control only takes into account local parameters. Other grid operational parameters are addressed by adding an extra control, namely the INCREASE overlaying control. INCREASE proposes to use a multi-agent control system to reach an optimal system. Each grid agent can be considered as a software entity that will be embedded in the grid-connected systems and is able to autonomously react to changes in that environment.
Results from the demonstrations will be also presented in the session. The laboratory demonstrations utilize real components and controllable devices. Furthermore, prototype of the controllable PV inverter was made and tested in the real-life laboratory environment. Field demonstrations are conducted in four different locations: the Netherlands (Alliander), Belgium (Eandis), Austria (Energienetze Steiermark) and Slovenia (Elektro Gorenjska).
All lessons learned by INCREASE partners are being aggregated over the project duration. In the last presentation Technical, economical and policy recommendations will be available to interested society and stakeholders.

Ultra-high Fidelity controller Hardware-in-the-loop Simulation for Power Electronics and Smart Grid
Speaker: Adrien Genic, Head of modelling team at Typhoon HIL
Description: Significant and growing penetration of smart inverters represents both challenges and incipient opportunities to increase utility grid agility and stability. In addition to inherently fast dynamic control capabilities, these power electronics systems interact with increasingly diverse physical systems (such as renewable generation technologies) in complex ways. Indeed, grid is becoming a true cyberphysical system with a layered architecture comprising both power processing and control and communications. Classical tools that are used for simulation, testing, and system validation are very limited in both model fidelity and flexibility. In this talk we will present a new approach to power electronics and power system controls testing and validation based on ultra-high fidelity controller Hardware-in-the-Loop (HIL) real-time simulation. Typhoon HIL platform enables ultra-high-fidelity real-time simulation of power electronics converters, microgrids, distribution and transmission networks, with 1µs simulation time step. In addition, our HIL simulation is directly interfaced with real digital controllers, thereby eliminating modeling assumptions and thus providing the most realistic “flight simulator” experiences for power electronics and power system simulations. We will discuss how Typhoon HIL is changing the testing and quality assurance processes in power electronics industry today and how we are helping, in our small way, utilities and system integrators revolutionize the grid.
