Abstract: Aiming at the problem of optimal resource allocation between microgrids with different source load characteristics, a source grid load and energy storage
The vehicle-to-grid (V2G) technology enables the bidirectional power flow between electric vehicle (EV) batteries and the power grid, making EV-based mobile energy storage an appealing supplement to stationary energy storage systems.

Low-time resolution electricity data have been used to drive battery energy storage system (BESS) planning due to data barriers. However, the coarse-resolution time series cannot reflect real power variation, and the planning results may be inappropriate due to the unrealistic representation of source-load uncertainties.
