Abstract：Aiming at the need of controlling frequency stability of low inertia system, model predictive control is adopted to design the control systems of rectifier and inverter separately through discretizing the mathematical models of voltage source converter HVDC (VSC-HVDC). This kind of control system has simpler structure, convenient parameter selection, fast dynamic response, and better robustness. It is easy to realize the control of the frequency fluctuation in low inertia sending system connected with VSC-HVDC. The paper analyzed the effects of DC transmission power regulation on frequency power modulation, and set up the simulation model that the low inertia system was connected to VSC-HVDC. Comparative studies were demonstrated between power modulation methods of traditional PI control and model predictive control. The simulation results show that the model predictive control can restrain the range of the frequency change and increase the speed of the frequency recover effectively.
