Optimal control model of electric vehicle demand response based on real — time electricity price

With wind power, photovoltaic and other intermittent new energy for large-scale parallel network, safe and stable operation of the grid is facing great challenges. To develop the energy storage system represented by electric vehicles and carry out flexible load demand side response, and to realize friendly interaction with the large power grid, it will help to cut the peak filling trough and improve the power grid peak and frequency modulation capability. Based on the real-time electricity price of the user, this paper studies the control method of the demand response of the electric vehicle, and maximizes the auxiliary service capability of the electric vehicle while ensuring the battery life and economic benefit.
