Item The FlexPlan Approach to Include the Contribution of Storage and Flexible Resources in Grid Planning(Institute of Electrical and Electronics Engineers Inc., 2020-09) Migliavacca, Gianluigi; Rossi, Marco; Siface, Dario; Marzoli, Matteo; Ergun, Hakan; Rodriguez, Raul; Leclerq, Guillaume; Amaro, Nuno; Matthes, Bjorn; Gabrielski, Jawana; Morch, Andrei; Tecnalia Research & InnovationThis paper describes the main features of the new European research project FlexPlan. This project aims at establishing a new grid planning methodology considering the opportunity to introduce new storage and flexibility resources in electricity transmission and distribution grids as an alternative to building new grid elements. FlexPlan will create a new innovative grid planning tool whose ambition is to go beyond the state of the art of planning methodologies, by including the following innovative features: integrated transmission distribution planning, inclusion of environmental analysis, probabilistic contingency methodologies replacing the N-1 criterion as well as optimal planning decision over several decades. Then, the new tool will be used to analyse six regional cases covering nearly the whole European continent, aimed at demonstrating the application of the tool on real scenarios as well as at casting a view on grid planning in Europe till 2050. In this way, the FlexPlan project will try to answer the question of which role flexibility could play and how its usage can contribute to reduce planning investments yet maintaining current system security levels. The project will end up formulating guidelines for regulators and planning offices of system operators.Item FlexPlan: testing an innovative grid planning tool using European wide regional cases(Institute of Electrical and Electronics Engineers Inc., 2022) Amaro, Nuno; Faifer, Izabella; Damanik, Oscar Aristo; Egorov, Aleksandr; Sperstad, Iver Bakken; Bastianel, Giacomo; Migliavacca, Gianluigi; Kallset, Vegard Viken; Rodriguez-Sanchez, Raul; Rossi, Marco; Garau, Michele; Garcia-Lazaro, Santiago; POWER SYSTEMSThe H2020 project FlexPlan considers the development and validation of an innovative grid planning tool. In this paper, we present the methodology used in the simulation toolchain and preliminary results for optimal power flow simulation performed in four different regional cases covering most parts of Europe. An energy scenario, created in the scope of the project, for 2030 is used and results obtained illustrate both the tool capability to run complex simulations and the need for grid reinforcements. Obtained OPF results will be further used in the project to identify grid expansion candidates and solve the grid expansion problem.Item Integration of offshore wind energy into an island grid by means of a Multi-Terminal VSC-HVDC network(Institute of Electrical and Electronics Engineers Inc., 2018-05-21) Haro-Larrode, Marta; Santos-Mugica, Maider; Etxegarai, Agurtzane; Eguia, Pablo; Tecnalia Research & Innovation; POWER SYSTEMSIn this paper, the connection of two offshore wind-farms to an island grid through a Multi-Terminal HVDC (MTDC) link is examined. The control strategy of the MTDC grid is validated against several adverse fault cases occurring at the island grid side. For this purpose an electrical grid model based on a medium size island is used to test the control structure of the MTDC link under faults such as voltage dips and frequency deviations. Simulation results are also presented thereby, pointing out interaction issues between control schemes of the MTDC and island grid. Thus, the participation of the MTDC network to increase the flexibility of the interconnected electrical system stands out in the present work.
