摘　　要：电压稳定裕度与系统无功备用密切相关,因此,提出一种无功源的无功备用优化方法。引入发电机参与因子来衡量发电机无功备用的重要程度,建立以系统无功备用最大化为目标的优化模型,并应用Benders分解将模型分解为发电机主问题和电容器子问题。IEEE 39节点系统算例验证了所提优化方法的有效性,优化方案大幅提高了系统电压稳定裕度。Since the voltage stability margin is closely related with the reactive power reserve, a reactive power re- serve optimization method for vat source is proposed. The participation factor of generator is used to measure the im- portance of reactive power reserve of generator. Taking the maximum reactive power reserve of power system as ob- jective, an optimization model is built, and then decomposed into master problem of generator and sub-problem of ca- pacitor by Benders decomposition. A case of IEEE 39-bus system verifies the effectiveness of the proposed optimiza- tion method, and the optimization scheme significantly improves the voltage stability margin of system.
