Impact of flexibility location in MV Distribution - The Nice Smart Valley Case study

Nice Smart Valley (NSV) is the French demonstrator of the European H2020 project INTERFLEX, aiming to operate the electric power system on a “local” scale through the use of flexibilities. This article presents, though simulation results, the impact of the localization of flexibility on volumes used to solve the electrical constraint(s). Two methods were used to assess the volumes of useful flexibility. The first one is based on the activation of homothetic flexibility all over the “useful” location. All flexibilities participating in the resolution of a constraint contribute in proportion to their original consumption. The second is based on “worst” and “best” combinations of flexibility placements. The results showed that on the three MV-grids of NSV the placement of flexibility may have a slight impact on the volume of useful flexibility whereas for voltage constraints, the placement of flexibility has a strong impact on the volume of useful flexibility.
