摘要
提出基于权函数的电力系统状态估计算法，该方法较好地综合了加权最小二乘法（ＷＬＳ）和加权最小绝对值（ＷＬＡＶ）两种估计方法的优点，仅需对应用广泛的ＷＬＳ软件作很少的修改即可实现该算法。在求解迭代过程中，以残差变化量作为加速因子，修正权函数，减少了迭代次数，加快了算法的计算速度。用ＩＥＥＥ３０和ＩＥＥＥ１１８节点系统验证了此方法的优越性。
This paper presents a new algorithm for power system state estimation based on weight function with the advantages of both WLS and WLAV. A little modification of WLS software is needed to achieve the new algorithm. During the solution iterations, the residual change is used as accelerating factor to revise weight function. As a result, the number of iteration and the calculation time are decreased. The proposed algorithm is tested on IEEE 30 and IEEE 118 bus systems.
