A Cost-Efficient Approach to EV Charging Station Integrated Community Microgrid: A Case Study of Indian Power Market

Abstract

Rising atmospheric adulteration due to exponential growth in urbanization, industrialization, and increasing the number of on-road vehicles is raising an alarming situation for urban communities. To mitigate the effects of this escalating issue, there is direct need for implementation of alternative fuel-based distributed generation and transportation system. In this paper, an optimal framework of energy management system (EMS) for public electric vehicles (EVs) charging station integrated with the community microgrid is proposed, based on switching mechanism from one trading market to another. The proposed framework is executed by formulating a mix integer, nonlinear problem under multiple trading locations. The aim of EMS is to minimize the cost of energy to charge the vehicle and to meet the community load, demand while maximizing the selling cost of the surplus energy of a solar photovoltaic system and the energy discharged by EVs. The proposed approach is applied to a 100-house community in the context of the Indian community, assuming each house governs one EV and returning charging station to charge and discharge the EV.
