摘要
以网络有功损耗最小为目标函数 ,考虑潮流无功平衡方程的等式约束和一系列电压和控制变量的不等式约束 ,使用 SQP序列二次规划法计算电压无功优化潮流。在形成目标函数和约束方程式时 ,没有将电压相角当做常数 ,而是认为支路有功潮流在优化过程中保持不变。对 Ward &Hale 6母线、IEEE 1 4母线和 IEEE 3 0母线系统分别进行电压无功优化计算 。
This paper proposes the method of SQP ( sequential quadratic programming) to calculate voltage/reactive power optimization power flow,considering the minimum losses of transmission line as objective function,the reactive power flow equations as equality constrains and the ranges of a set of voltage and control variables as inequality constrains.While deducing the objective functions and constrains equations. the angle of voltage is not considered as constant but the active power of transmission lines remains unchanged during the optimization procedure.Moreover,results of the reactive power optimization in Ward & Hale 6,IEEE 14 and 30 bus systems show that this method has stable convergence.
