Stationary BES Coupled with Solar PV for an Energy Shared Home with an EV

This study examines the optimal combination of stationary battery energy storage (SBES) and solar photovoltaic (SPV) components for grid-tied homes with electric vehicle (EV) when electricity is shared with a neighbor. In this paper, Load-1 refers to the home with SPV-SBES and EV that shares electricity with Load-2. The optimization is performed to obtain the lowest possible cost of electricity (COE) for Load-1 and to reduce the COE for Load-2 over the project lifespan, considering the design constraints. Utilizing realistic yearly data of the solar irradiance, temperature, load consumption of each dwelling, and EV, the capacity of SPV and SBES is determined to achieve optimal results. The time of departure, the time of arrival, and the initial state of charge at the time of arrival are all subject to EV uncertainty. The devised optimization method is applicable to all grid-connected homes that are willing to share their electricity with a neighbor. The configuration is subjected to sensitivity, uncertainty, and operational analysis when energy is shared between households and L1 has SPV, SBES, and EV.
