基于关联矩阵和动态规划法的地区电网无功优化
针对目前时段划分中对动作次数的处理和模型简化方面存在的问题,设计设备状态的关联矩阵,并据此进行时间区间划分。在此基础上,对每个时段进行静态无功优化,保留每个时刻的最优解和部分次优解,并将这些解作为动态规划的状态变量。在各时段中用动态规划法以动作次数最小为目标寻找最优路径,从而得到整个调度周期的动态无功优化问题的解。某实际地区电网算例说明了时段划分和基于此的动态无功优化方法的有效性。...

| Bibliography: | dynamic reactive power optimization; district power grid; dynamic programming; associated matrix on equipment state In order to solve the problem of action number handing and model simplification in present time division, the associated matrix on equipment state is designed and the time is divided into several intervals based on this matrix. And then static reactive power of each time interval is optimized, the optimum solution and second best solution of each time interval are reserved. Then these solutions are used as state variables of dynamic programming to search the optimum path which has smallest time of action using dynamic programming in each time interval. At last, the solution of dynamic reactive power problem during whole scheduling period can be gotten. An example of region power system shows the effectiveness of time division and dynamic reactive power optimal method based on it.
