摘要：
The new power system is facing a severe frequency stability situation in the rapid transformation, and the pressure on the anti-destabilization control line belonging to the safety and stability control framework has sharply increased. On the basis of constructing an active frequency response control framework of“online budgeting and real-time matching”, taking into account emergency control costs, this paper proposes an optimal control strategy of active frequency response that coordinates safety and economy. According to the dynamic characteristics of frequency response of different frequency regulation resources, a regional power system frequency response model is constructed. From the economic point of view, the control principle is designed with the safety and economic coordination as the optimization goal, and the active frequency response optimal control strategy based on model predictive control is constructed. Through the optimal regulation of the action depth of frequency regulation resources, the emergency control cost on the premise of frequency safety is further reduced. Simulation analysis shows that the proposed strategy can optimize and coordinate frequency regulation resources with different endowments, while achieving safety and economic coordination of active frequency response control. © 2023 Automation of Electric Power Systems Press.
