Abstract: 

EU committed to lower greenhouse gas emissions by 40% in 2030 with respect to 1990 and to reach a share of renewables of at least 27% by 2030. These targets aimed to help the EU achieve a more competitive, secure and sustainable energy system and to meet its long-term 2050 greenhouse gas reductions target. According to [3], the EU28 as a whole is on track to meet and even exceed its 2020 GHG targets. This is also supported by the positive evolution of renewable penetration, where the EU 28 has met its interim target. The increasing share of fluctuating Renewable Energy Sources (RES) has become key to improve the carbon footprint of the European electricity system and achieve energy and climate change policy goals. This increase has been accompanied –and facilitated- by an emerging decentralized RES ecosystem and the promotion of specific interconnection projects. Even though he countries in South Eastern Europe are on track to achieve their RES penetration targets, the region still has a huge potential especially with regards to PV and Wind production – to become a clean energy breeding ground for Europe. This high interconnection rate between countries not only serves to mitigate the external dependency – still high for some countries – but also to efficiently manage the common production capacity of the region. Whilst some western countries, have a rather high excess of installed capacity, SEE has managed to keep constrained the capacity costs. This is critical in a scenario where larger RES penetration is expected: it is necessary to keep the balance between installed capacity and interconnection costs, optimising not only the physical connections, but also the way they are used to promote the adoption of clean energies. It is in this context where regional energy balancing becomes a priority. A set of solutions boosting regional cross-border cooperation, balancing and re-dispatching of zonal resources, by considering also cross-border congestions (cross-border capacity) and specific organization of ancillary services markets and mechanisms in each South-Eastern national market is necessary and will be addressed by H2020 project CROSSBOW that all regional TSOs are part off. The panel of top industry leaders from the regional TSOs will discuss these and other questions related to operation and collaboration of regional TSOs.

Industry panel #1.3 – Power quality challenges and solutions in transmission networks with high penetration of power electronics – interim results of EU H2020 project MIGRATE

Organizer:

Boštjan Blažič, University of Ljubljana, Slovenia

Panelists:

Dejan Matvoz, Elektroinstitut Milan Vidmar Ljubljana, Slovenia
Jaka Žvab, University of Ljubljana, Slovenia
Jako Kilter, Tallinn University of Technology, Estonia
Jovica Milanovic, University of Manchester, UK
Kai Strunz, Technische Universitat Berlin, Germany

Abstract: 

One of the focuses of the Migrate project is the evaluation of power quality (PQ) issues expected in future transmission networks due to high penetration of power electronic (PE) devices. PE devices, such as PE-interfaced wind generators, FACTS devices and HVDC links, are indeed one of the major sources of network disturbances (harmonics, flicker, voltage and frequency variations), while also being very sensitive themselves to PQ disturbances. The goal within the Migrate project is to propose a methodology for the evaluation of PQ levels in future power networks, where a high-share of PE devices is expected. The addressed topics include PE-device simulation models for PQ studies at transmission level, PQ measurements with PMUs and a probabilistic methodology for the assessment of disturbance propagation.

Industry panel #2.1 – Microgrids as Enablers in DER Integration

Organizers:

Aleksi (Esa) Paaso, Commonwealth Edison

Panelists:

Amin Khodaei, University of Denver, USA

Abstract: 

Though the concept of microgrids is not new, there is a significant amount of innovation occurring in the field. Utility-operated microgrids not only offer significant improvements in regional resilience, but also enable valuable experience and research-based insights that can improve the design and operations of the broader distribution grid. The speakers will address cutting-edge research associated with the development of a microgrid master controller (MMC) and other major advancement in application of microgids for integration of distributed energy resources (DER) in distribution systems. They will address additional learnings on crucial topics such as how an MMC can optimize the use of solar PV and storage within a microgrid, what are the benefits associated with a microgrid project, and how syncrophasors can support the development of advanced operations like islanding. Practical examples of utility microgrid, such as the Bronzeville Community Microgrid by ComEd, which can operate a clustered microgrid, and will be commercialized and implemented by the end of 2019 will be presented. The results and lessons learned from the development of the state of the art BCM utility microgrid can be leveraged for advancement of this technology in Southern European power grid. In summary, the panelists will discuss how practical challenges can be overcome by a collaborative approach between research, development and implementation experts to lead the field forward.

The project is expected to develop a framework and algorithms that will provide guidance to deploy advanced techniques in order to facilitate an increased cross border power transfer at the national and transnational level, while ensuring at all times network voltage, angular and frequency stability. The session will provide a general overview of the project vision and its expected contributions to facilitate the operational flexibility of transnational power networks with a high penetration of renewable energy resources. It will present about the Wide Area Monitoring System (WAMS/WAMPAC) information, which will facilitate (a) real-time decision making, (b) faster and more recise stability problems localization, (c) identification of important factors for WAMPAC implementation, and (d) automated decision-making systems based on WAMS data for increasing the reliability of the power system. Following that, the panel will discuss about the legislative and regulatory issues to facilitate cross-border power exchange and maximizing the benefit of transnational wholesale market. Furthermore, the discussion will be focused on electrical energy storage resources connected at TSO and DSO networks. Also, the session will give a brief overview of the current situation in the transmission system of Bosnia and Herzegovina as well as future prospects in terms of cross – border management solutions foreseen by the CROSSBOW project.

Abstract: 

With the ultimate aim of unlocking the full potential of Europe’s offshore resources, PROMOTioN addresses technical, legal, regulatory, economic and financial barriers to the implementation of a meshed offshore HVDC transmission network. By connecting key stakeholders from industry, academia consultancies and transmission system operators, PROMOTioN both provides a platform for interdisciplinary development as well as increases acceptance of required novel technologies and frameworks.
The work of promotion is centered around a number of key challenges related to the development of such offshore DC grids. In this panel, the focus will be on the developments in the field of DC grid protection. The panel will discuss the detection of faults, the development of a multi-functional DC relay, DC breakers and their modeling, risk-based analysis of different protection strategies and the fault ride through behavior of DC connected wind farms.
