Energy-based Robust Control of Power Systems with SVC and Nonlinear Loads

Using the energy-based method, this paper investigates the robust control of power systems equipped with static var compensator (SVC) and nonlinear loads. First, the uncertain nonlinear differential algebraic equation model is constructed for the power system. Then, the dissipative Hamiltonian realization of the system is completed by the means of pre-feedback control. Finally, based on the dissipative Hamiltonian realization, a robust controller is put forward. The proposed robust controller can effectively utilizes the internal structure of the power system. Simulation results verify the effectiveness of the control scheme.
