摘要
交直流系统之间的耦合程度受控制变量选择的影响。适当地选取直流系统控制变量以及妥善处理换流器转换方程,不仅可以使直流网络方程与交流网络方程解耦,而且可以使拉格朗日乘子也相应地解耦。通过解耦,交直流最优潮流的计算时间与纯交流系统最优潮流的计算时间相差甚微。
The coupling between the AC subsystem and the DC subsystem varies with the control variables of the DC subsystem. Through suita-bly selecting the control variables of the DC subsystem and reasonably treating the converter equations, the DC network calculation and the AC network calculation are completed independently, and so are the corresponding Lambdas. By means of decoupling technique, the execution time of AC/DC optimal power flow is slightly longer than that of pure AC optimal power flow.
