| 摘 要： | 针对电力系统优化运行控制的最优潮流问题,采用内点割平面法求解多重解的线性规划问题,算法迭代次数多,计算速度低,严重的可能导致算法不收敛.为此提出一种识别最优基的方法,通过对优化问题的解空间进行旋转和映射,将最优解沿可行域的棱移动至顶点,得到问题的最优基,从而解决原算法失效的问题.进一步采用随机扰动法和阶梯矩阵变化法提高算法的计算效率,平均计算时间缩短了20%左右.对电力系统标准测试系统IEEE14 300节点系统的数值仿真结果表明,改进算法能够正确处理最优解的各种情况,扩大了内点割平面法的应用范围.

| Abstract: | The research of optimal power flow simulation in power systems finds that interior point cutting plane method (IPCPM) fails to solve the linear programming problem which has multiple solutions.A new general optimal base identification method was presented to solve the above problem by revolving and mapping the solution space,which could move the optimum along the edge of the feasible region to the vertex of solution space.Furthermore,two measures,stochastic disturbance method and ladder matrix method,were u... |
