Introduction Distributed Resources (DR), including both Distributed Generation (DG) and Battery Energy Storage Systems (BESS), are integral components in the ongoing evolution of modern power systems.
Due to the increasing installation of residential electric vehicle (EV) chargers to benefit from the low tariff rates during off-peak hours, the simultaneous charging of a large number of EVs affects the voltage profile and the transformer loading of a radial distribution network.
Systems for storing energy in batteries, or BESS, answer these issues. Battery energy storage systems (BESS) are essential in managing and optimizing renewable energy utilization and guarantee a steady and reliable power supply by accruing surplus energy throughout high generation and discharging it during demand.
The charging of EVs usually occurs at low-priced off-peak grid periods at night. We utilized the datasheet's information of the most popular EVs in the UK market, such as Tesla, Nissan Leaf, BMW… etc. . The energy capacities of different EV batteries vary between 40 and 103 kWh, as shown in Fig. 5 (b).
