Optimal placement of photo-voltaic array and electric vehicles in distribution system under load uncertainty

This paper presents a simultaneous optimal placement of photo-voltaic (PV) array and Electric Vehicles (EVs) in distribution system for real power loss reduction and voltage profile enhancement. The optimal allocation of PV array and EVs in distribution system is identified through Artificial Bee Colony (ABC) population based meta-heuristic optimization algorithm. In addition, uncertain load demand of 24 hours for each bus is considered in this study. The power generated by PV array at solar irradiance s for each hour is injected into grid for improving the power loss reduction. EVs Charging and discharging during 24 hours are also being discussed in this paper. In charging mode the EVs act as a load on the system while in discharging mode EVs behave as a power source and transfer power to a network for fulfill the load demand. Different case studies related to PV and EVs are analyzed under load uncertainty. Simultaneous placement of both indicates better results.
