Abstract
The 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.
