Calculation Method of Dispatchable Potential of Bus-specific Charging Stations and Its Application in the Spot Market

As China's carbon peak and carbon neutrality goals are proposed, energy storage adjustable loads, represented by electric vehicles, serve as an important carrier to promote new energy consumption and will have huge room for development in the future. However, energy storage adjustable loads such as electric vehicles are still in the exploratory stage as emerging market entities participating in power market transactions. This paper considers the dispatchability potential of electric vehicles as load-side storage resources, proposes a calculation method for the dispatchability potential of electric vehicles after aggregation based on the Monte Carlo method and Minkowski sum, and finally uses buses and private cars to calculate an example was calculated and simulated in the IEEE30 node for the bus dedicated charging station access test system. This method reasonably describes the charge storage potential of electric vehicles and can realize the interaction between electric vehicles and the power grid.
