针对计及风电主动支撑控制策略的电力系统，开展优化调度策略研究，旨在提升系统频率安全与运行经济性。首先，构建系统频率响应模型，推导以最大频率变化率、频率最低点、准稳态频率偏差为核心的频率安全约束条件，为调度策略设计奠定理论基础。继而，提出融合频率安全约束的机组组合优化模型，以系统运行成本最小化为目标，在常规机组组合模型中嵌入线性化的频率安全约束，解决风电出力随机性与传统调度模型动态特性考虑不足的问题。最后，通过Matlab在IEEE 14节点和RTS-79系统中仿真验证，结果表明，所提策略可显著降低频率越限风险，在火电机组与风电场调度分配中实现经济性与安全性的协调平衡。

This paper conducts research on optimal dispatch strategies for power systems incorporating active support control strategies of wind power, aiming to enhance system frequency security and operational economy. First, a system frequency response model is constructed, and frequency security constraints are derived with the core of maximum frequency change rate, minimum frequency point, and quasi-steady-state frequency deviation, laying a theoretical foundation for dispatch strategy design. Then, an optimal unit commitment model integrating frequency security constraints is proposed. With the goal of minimizing system operation costs, linearized frequency security constraints are incorporated into the conventional unit commitment model to address the issues of randomness in wind power output and inadequate consideration of dynamic characteristics in traditional dispatch models. Finally, simulation verification is carried out via Matlab in the IEEE 14-bus and RTS-79 systems. The results show that the proposed strategy can significantly reduce the risk of frequency violations and achieve a coordinated balance between economy and security in the dispatch allocation of thermal power units and wind farms.
