Abstract：This paper studies the load frequency control(LFC)of power system with electric vehicle(EV).Firstly,combining the EV model with the traditional load frequency control model,an adaptive sliding mode control law is de-signed under unknown disturbance fluctuation range.Secondly,the matched and unmatched disturbances in power network frequency modulation are considered,and the sufficient conditions for system stability under matched and unmatched con-ditions are derived using Lyapunov stability theory.Finally,the simulation results of two regional power systems show that electric vehicles can improve the frequency stability of the power grid as both power source and load,and the designed controller can effectively adiust the frequency fluctuation of the power grid.
