Abstract：The global energy structure is gradually shifting toward clean and low-carbon sources, and the large-scale integration of renewable energy into power systems has become inevitable. The intermittency and volatility of renewable energy generation, such as wind and photovoltaic power, pose significant challenges to grid stability. Issues like increasing frequency fluctuations, reduced voltage support capability, and declining inertia levels are becoming increasingly evident. Traditional power system operational control logic struggles to adapt to the complex operating conditions arising from high-proportion renewable energy integration. This paper optimizes electrical control strategies, explores specific approaches to improving inverter control algorithms and coordinating multi-energy complementary operations, and enhances the system’s disturbance response capability. Research findings indicate that virtual synchronous generator control technology can simulate the inertia and damping characteristics of conventional synchronous generators, improving frequency response performance after renewable energy integration. By combining adaptive voltage regulation strategies with rapid power compensation from energy storage systems, it can suppress voltage fluctuations at grid connection points and enhance dynamic stability during fault ride-through periods.
