Optimal sizing and siting of distributed generation and EV charging stations in distribution systems

Abstract

The penetration of distributed generation (DG) units in distribution systems has gradually increased. In addition to that, the interest in the electrification of the transport sector has brought about increasingly significant incentives for the adoption of electric vehicles (EVs). In this regard, the planning of the installation of DG units and EV charging stations should be carefully considered by system operators (SOs) in order to avoid stressing the network and extract operational flexibility. In this study, an optimal sizing and siting approach is proposed for DG units and EV charging stations. Furthermore, this study considers the time-varying nature of demand and production, which enables a more realistic outlook for the problem compared to a static consideration. The proposed approach is tested on a distribution system feeder in Istanbul, Turkey.
