Sizing of a power electronics-based voltage regulating device to support the integration of photovoltaics and electric vehicles in LV grids
Résumé
This paper presents a method for sizing a voltage regulation device based on power electronics structures applied to the low voltage distribution grid, in a context of increasing penetration of distributed energy production and electric vehicle charging stations in residential installations. The case studies presented and used in the analyses take into account the scenarios published in Enedis (French main DSO) and RTE (french TSO) reports regarding predictions for the evolution of the French electrical grid up until 2050. The operation mechanism of the power electronics device is diverse and its connection at the secondary busbar of a LV substation can be made both in series or in parallel. In this paper we address the effect of the parallel-connected device, given the similarity of its configuration to the wiring of other power electronics-based elements attached to the distribution grid.
