A microgrid (MG) system based on a hybrid energy storage system (HESS) with the real-time price (RTP) demand response and distribution network is proposed to deal with uncertainties.
The charging and discharging price of EVs in the process of participating in V2G is based on the RTP of each area. EVs will charge in periods of low electricity prices and discharge in periods of high electricity prices according to economic attributes to obtain benefits.
Using MG to facilitate integration of distributed energy into the grid is a solution for multi-energy complementary integration optimization (Valibeygi et al., 2021). The application of demand-side management means can make the load more adaptable to the uncertainty of the RES generation side.
Host grid reliability, electricity rate uncertainty, electricity demand beyond installed capacity, and regulatory and market incentives are some of the drivers motivating the deployment of microgrids.
