Scheduling of Electric Vehicle for Performance Improvement of Electricity Distribution Network: A Case Study in Indian Scenario

Electric vehicles (EVs) are going to play a significant role in the future transportation system. Identification of suitable charging slots for EVs is a complex problem. Further, EV batteries can be used purposefully for ancillary services in residential electricity distribution networks. This paper proposes a charging and discharging scheduling approach for EVs at residential buses to improve the performance of the electrical distribution infrastructure. The performance of the electricity distribution system has been measured in terms of daily average real power losses of the whole network and the average voltage deviation of the buses. The performance of the network is optimized by the application of the particle swarm optimization (PSO) technique and the grasshopper optimization algorithm (GOA). The adequacy of the proposed method is tested on a typical 28-bus Indian distribution network. Different case studies have been performed on weekday and weekend days, and satisfactory results are obtained for both cases.
