TOWARDS USING AN ACTIVE / REACTIVE SIMULATION TOOL FOR GRID DEVELOPMENT STUDIES
Jérôme Henry · KTH Publication Database DiVA (KTH Royal Institute of Technology) · 2008
As part of the KTH civil engineer degree, this final degree project was done at RTE, the company responsible for operating, maintaining and developing the French electricity grid, within the group responsible for the 400 kV grid and interconnection studies. After studying how adding production influences flows in a neighboring area, in order to get familiar with simulation tools, the next step was to work on RTE’s grid model, aiming at updating it with reactive data. Moreover, another task has been to analyze, understand and solve problems with the group’s active-reactive simulation tool. During these months, methodologies were developed to construct more accurate reactive data assumptions for 2015. Then, some methods proved being solid enough to quickly obtain valid and useful data, some others have not. Finally, a solution was also developed, allowing the group’s engineer to overcome errors in how power balance is treated within the active-reactive simulation tool. The method should be implemented in an upcoming release of the tool. Of course, considerable knowledge on how a grid works and is operated was acquired by working at RTE, and furthermore it also helped to understand a company’s daily organization and all what it implies.
