A Mode-selection Control Strategy of Energy Storage Charging Piles

A mode-selection control strategy of energy storage charging piles is proposed in this paper. The operation mode of energy storage charging piles can be selected by the user first, then the system will automatically determine it according to the operating state of the power grid, the electricity price, the SOC of the energy storage battery and the charging quantity of the electric vehicles. This control strategy can not only improve the economic benefits, but also promote the safety and stability of the power grid. The charging and discharging model of energy storage charging piles is established in MATLAB/Simulink to verify the feasibility of the proposed control strategy.
