EU-SysFlex webinar | Mitigation of technical scarcities associated with high levels of renewables on the European power system


FRIDAY, 14 JANUARY 2022, 10:00-12:00 CET  |  TEAMS webinar

EU-SysFlex would like to invite you to a webinar on the topic of Mitigation of technical scarcities associated with high levels of renewables on the European power system.

Over 4 years of work, technical power system studies have identified various technical shortfalls when scenarios with levels of renewables beyond 50% are applied. The scarcities investigated include frequency stability, voltage stability, rotor angle stability, congestion, and restoration. Studies have been performed to test the capabilities of various flexibility solutions to mitigate these scarcities in: the Ireland and Northern Ireland power system (all scarcities), the Polish transmission system that is connected to an approximate model of neighbouring countries (voltage and rotor angle), the Continental Europe (frequency and balancing).

The webinar will present the results of the recently published Task 2.6, final deliverable of WP2.

EU-SysFlex is a Horizon 2020 project aimed at identifying the long-term needs as well as the technical scarcities of the future power system. The objective of the project is to create a long-term roadmap for large-scale integration of renewable energy in electricity grids as well as provide practical assistance to power system operators across Europe. The project team is working on identifying improvements to European market design, regulation, operational practices and enhanced system tools. EU-SysFlex is a project made up of a pan-European consortium, crossing the industry spectrum from TSOs, DSOs, technology providers and consultants as well as research and academic institutes from 34 organisations across 15 European countries.

Speakers info:

Ye Wang

He received in 2009 the BSc and MSc degrees in electrical engineering from both Ecole centrale de Lille and Université des Sciences et Technologies de Lille, France. He got a PhD from Ecole centrale de Lille, France in 2012. Y. Wang has been employed by EDF R&D as a research engineer since 2012 and has significant experience in power system analysis, grid integration of renewable generation as well as in control and management of distributed resources.


Caroline Bono

Caroline Bono, PhD has more than ten years experience in the energy and numerical simulation sectors. At EDF since 2008, she has conducted several strategic analyses on the French power sector and was strongly involved in the assessment of renewable energy integration and the induced flexibility requirement. She has a strong experience in scientific computing through several research positions at the Lawrence Livermore National Laboratory (USA) and at the Lawrence Berkeley National Laboratory (USA) from 2002 to 2008. She holds a PhD in Mechanical Engineering and Scientific Computing from the University of Michigan, a MS in Mechanical Engineering from the University of Michigan and a Diplôme d’Ingénieur (BS) from the Ecole Nationale Supérieure de Techniques Avancées, Paris, France.


Mateusz Skwarski

Mateusz Skwarski was born in Poland, in 1993. He received (with honors) the BSc and MSc degrees in electrical engineering from the Faculty of Electrical Engineering, Warsaw University of Technology (WUT), Warsaw, Poland, in 2017 and 2018, respectively. Since 2018, he has been employed with the Research and Development Centre in PSE Innowacje sp. z o.o. as an power systems analyst. He is currently working toward the PhD degree with the Electrical Power Engineering Institute, WUT. His research interests include power systems and especially power system stability analysis.
