OPTIMAL ALLOCATION PROVISION FOR EV CHARGING STATIONS IN THE LOW VOLTAGE DISTRIBUTION SYSTEM

The integration of Electric Vehicles (EVs) in the distribution system is expected to rise within the following years posing technical challenges to the reliable operation of the electrical system. The increased use of EVs required a planned charging structure to minimize the disturbances and infrastructure augmentation in distribution system. Due to finite battery capacity and elongated charging time, it is essential to determine the optimal allocations of EV charging infrastructure in distribution system. This work presents the minimum increase in active power loss based optimal allocation of EV charging stations while maintain the prescribed power system constraints including voltage limits. The proposed methodology is demonstrated with IEEE 33 bus distribution system. In the optimization, Grey Wolf Optimization (GWO) algorithm is used. The results show the effectiveness of proposed methodology
