摘要
基于扩展等面积准则(EEAC)这一稳定性量化分析理论和算法,提出了求解含暂态安全稳定约束的最优潮流(OTS)计算方法。该方法将OTS分解为最优潮流(OPF)和暂态安全稳定预防控制2个子问题。基于安全稳定模式的预防控制在OPF运行点上求取满足暂态安全稳定约束的优化经济调整方案,据此将暂态安全稳定约束转化成相应控制变量的不等式约束,并以此作为OPF计算的附加约束条件,通过OPF和预防控制2个子问题的"相互解耦,交互迭代"得到OTS的解。以广东电网为仿真算例验证了算法的有效性。
Based on the quantitative analysis theory and algorithm of power system stability,i.e. extended equal area criterion （EEAC）,a new method is presented for implementing transient security constrained optimal power flow （OTS）. The method divides OTS into two sub-problems,namely the conventional OPF and transient security preventive control. The stability mode based preventive control searches optimal preventive control measures subject to transient stability and security constraints on the basis of OPF operating point. According to the preventive control calculation results,transient stability and security constraints are converted into inequality constraints of control variables which are incorporated into OPF model. OTS is therefore solved by this decoupling and iteration process of the two sub-problems. The effectiveness of the new method is verified by the simulation results using Guangdong power system data.
