Findings

EVs' batteries can be managed to meet system requirements without additional storage.

Sensitivity analyses show impact of battery degradation costs, solar irradiance, and inverter capacity.

Proper EV management improves microgrid performance during peak hours.

Abstract

Microgrids with AC/DC architecture benefit from advantages of both AC and DC power. In this paper, daily operation problem for a zero-carbon AC/DC microgrid in presence of electric vehicles (EVs) is considered. In this framework, EVs' batteries are mobile energy storage systems, which allow desirable operation of the microgrid during peak demand hours. This study shows in absence of storage system, EVs' batteries can be properly managed to satisfy the system requirements. In the case studies, several sensitivity analyses based on variations in battery degradation costs, solar irradiance, and inverter capacity are investigated.
