The basic concept is to use electric vehicles as mobile energy storage devices. They charge during off-peak electricity hours and discharge to nearby buildings or the grid during peak hours. By doing so, electric vehicles can take advantage of the price differences between peak and off-peak periods, thereby reducing the cost of vehicle usage.
By using the energy storage charging pile''s scheduling strategy, most of the user''s charging demand during peak periods is shifted to periods with flat and valley …
