Impact analysis of Integrated Renewable Energy Sources and EVs charging demand on the Distribution System

This research delves into the distribution system's Electric Vehicle (EV) Charging Arena with integrated coordination of Renewable Energy Sources (RES). Queuing theory assists in simulating the charging demand of EVs on an hourly basis in the daytime at the EV's charging center (CC). At the same time, the CC behaves as an Electric Vehicle Parking Lot (EVPL) at night. To better predict the arrival phenomena of EV keepers to charge their owned EVs while accounting for the heterogeneous Poisson process, the database of Local traffic density of Jonsvannsveien vest for Steinanvegen (Norway) is used. The Battery Charging Behaviour Model is included to estimate the time each EV takes to get charged in a single session (BCB). The Renewable Energy Feed-in Tariff (REFIT) database allows the EVPL to estimate the residential load of approximately 200 households. The rising charging demand for EVs also necessitates the integration of renewables to mitigate the unfavourable impacts on the system. The minimum voltage and losses in the IEEE-33 distribution system with the incorporation of CC and RES are investigated.
