摘要

西电东送战略的实施在广东形成一个多条高压直流（HVDC）馈入的大型受端电网，迫切需要进行动态电压支撑的优化规划，利用有限的投资最大限度地满足广东受端电网电压稳定性的需要。首先基于风险评估思想，结合系统故障后的状态转移过程来计算电压崩溃损失，从而实现了动态电压支撑安全效益的经济性量化。在此基础上建立了受端电网动态电压支撑优化模型，以补偿的年均效益最大化为目标函数，满足多种状态下的约束条件。最后基于静态的负荷裕度分析和动态的仿真分析，在广东电网上的仿真计算验证了所提出的模型的合理性和有效性。

Abstract

A large multi-HVDC infeeded receiving power network is being formed in Guangdong with the strategic plan“west-to-east power transmission” being implemented. Optimal planning is in urgent need to furthest meet the demand of dynamic voltage stability of the receiving network with the finite investment. The voltage collapse loss is evaluated based on risk assessment theory and post-contingency state transition analysis， by which economic assessment for security benefit of dynamic voltage support can be realized. A new model of dynamic voltage support optimization for receiving networks is then presented， in which the objective function is set to maximize the annual average benefit while meeting constraints in various conditions. Finally through the static load margin analysis and dynamic simulation on Guangdong power grid， the validity of the model proposed is proved and demonstrated.
