Abstract：A coordinated load-frequency control system of energy storage device and automatic generation control in an interconnected power system based on multivariable generalized predictive control theory is established. The regional coordinated controller is built as the supervisor controller for energy storage device and automatic generation control. By using the information of wide area measurement system, the regional coordinated controller predicted the trajectories of frequency and tie-line power flow based on the system controlled auto-regressive integrated moving average model and performed the optimized coordination of each frequency modulation device taking the capacity of energy storage device, generation rate constraints, spinning reserve and minimum stable power output of thermal unit into fully consideration. Simulation results indicate that the proposed coordinated load-frequency control system can improve the stability of interconnected power system effectively. Meanwhile, the system is robust to various load disturbances.
