Abstract: With the continuous growth of new energy grid connected capacity, the impact of its power generation instability on the power system cannot be ignored, especially in the context of building a new power system. It is urgent to improve the perception and control level of new energy generation units. Therefore, a new energy panoramic monitoring and lean control technology based on grid stability control system is proposed to improve the level of new energy perception and optimize the means of new energy control. The proposed optimal control technology is verified by simulating the power grid fault in the new energy station. The results show that the power grid stability control system can realize the fast and accurate control of the new energy generation units through this technology.
