摘要
为解决连续潮流法在不平衡功率分配原则上存在的不足,将动态潮流引入到经典连续潮流法中,根据发电机和负荷的功频静特性系数分担不平衡功率,建立动态连续潮流模型。同时,为寻求控制变量的最优组合,解决优化过程陷入局部最优的问题,引入增加沿途搜索策略的改进捕鱼算法,求取表征系统静态电压稳定的功率裕度。通过IEEE6、IEEE14标准节点系统进行计算和仿真,验证了该理论的有效性。
In order to remedy the disadvantage of continuation power flow method in distribution of unbalanced power, this paper brought in dynamic power flow into traditional continuation power flow method, by which unbalanced power is distributed based on frequency static coefficient of generator and load, and establishes the dynamic continuation power flow model. At the same time, the improved algorithm simulating fishing along the search is brought in to solve the static voltage stability margin for seeking the optimal combination of control variable and solving the local optimum during node system verifies the effectiveness optimization. The calculation and simulation with IEEE6, IEEE14 standard of the algorithm.
