PresentationIntegration of Renewable Energy

TranscriptWebinar audio transcript

The Clean Energy Solutions Center, in partnership with ISGAN, hosted this webinar on lessons learned from GRID4EU, a European project on integrating renewable energy. Participants learned about the GRID4EU, which was recently recognized by the Clean Energy Ministerial as the best worldwide example of Excellence in Smart Grids for Renewable Energy Integration.

As a leading smart distribution networks project supported by the European Union (EU), GRID4EU is anchored in the European ambition to reach at least 27% of renewable energy by 2030. Driven by large-scale demonstrators, GRID4EU increases the hosting capacity for renewable energy sources (RES) in distribution grids without jeopardizing quality of supply. The project helps create a standardized European model for smart grids by fostering economically viable, technologically sound and interoperable solutions and by facilitating their replication and scale-up.

To develop patterns of RES integration and identify and articulate best practices and solutions, the GRID4EU project uses three locations representative of the current European RES landscape.

  • In Germany, GRID4EU improves the surveillance and advanced control of the medium voltage (MV) grid based on an autonomously acting multi-agent system. Dynamic topology reconfiguration, a new operational concept facilitating RES integration, is enabled.
  • In Italy, the project increases the hosting capacity and maximizes the integration of RES in the MV network. The system makes possible a new network management system model with distributed generators actively supporting voltage regulation.
  • In France, a network energy manager using solar generation and load forecasts creates an optimization program based on load flexibility bids. These bids, proposed by aggregators, ease the voltage and current constraints resulting from a high level of photovoltaic tied into the low voltage distribution grid. A unique 250-kW islanding test with no spinning machines is being conducted.

During the webinar, original approaches used in GRID4EU were presented by GRID4EU operational leaders. Presentations were followed by an interactive question and answer session with the audience.


Rémy Garaude VerdierRémy Garaude Verdier, Electricité Réseau Distribution France (ERDF)

Rémy Garaude Verdier is a Smart Grids Project Manager within Electricité Réseau Distribution France (ERDF). He is a civil engineer with an MBA from Lausanne IMD (Switzerland). He has worked in a variety of jobs during a 10-year career at EDF Group. His previous roles include managing the integration of the EDF Group’s SAP solution to its new nuclear build division in the UK and the US, and managing the purchase and engineering domains in the biggest SAP deployment completed to date (more than 80,000 users). Prior to joining EDF Group, he managed several large construction projects around the world for VINCI Group. Since 2011, Garaude Verdier has been GRID4EU project coordinator.

Lars Jendernalik Dr. Lars Jendernalik, Westnetz

Dr. Lars Jendernalik is responsible for the regional grid operation of primary substations in the region of Ruhr-Niederrhein of Westnetz, the largest distribution system operator in Germany. Previously, he worked in different positions of asset management for more than ten years. He is engaged with questions of distribution systems, the grid integration of decentralized energy resources and especially the development of asset management, grid planning and grid operation for more than 15 years. Additionally, he is involved in the management of nationally and internationally funded research projects (smart grids, grid planning). Furthermore, he gives a lecture about “power networks” at the Technical University of Dortmund. Within GRID4EU, Dr. Jendernalik is operational leader of the German Demo (Demo1).

Daniele SteinDaniele Stein, ENEL Distribuzione S.p.A

Daniele Stein is a Smart Grids Project Manager for ENEL Distribuzione S.p.A. He graduated with a MSEE degree from the University of Pisa in 2006, also the year in which he started working at ENEL’s Research Centre of Pisa. From the beginning of his experience with ENEL, Stein has worked in different network management areas, from network planning to operation and maintenance, and he has gained experience on network automation and control. In the last four years, he has been deeply involved in the development of European and international projects. Within GRID4EU, Stein is operational leader of the Italian Demo (Demo4).
