摘要
针对无功优化计算中离散变量和连续变量共存问题 ,提出用直接非线性原—对偶内点法内嵌罚函数的新算法。通过对几个不同规模试验系统计算分析 ,并与 Tabu搜索法求得的结果比较 ,证明了该方法是有效的 ,而且在计算速度、收敛性和优化精度上都优于 Tabu搜索法。
A new algorithm for reactive power optimization problem involving both discrete and continuous variables is presented, which incorporating a penalty function into the nonlinear primal-dual interior point algorithm. By comparing with Tabu search method, the numerical results of several test systems show that the proposed method is effective, and is superior to Tabu search method on side of computation speed, convergence and optimization accuracy. The effectiveness and practicality of the interior point algorithm in solving nonlinear mixed integer programming model of reactive power optimization is improved.
