摘要
为了保障电网安全稳定运行,结合当前条件,提出了一种求解电力系统最优潮流方法-原-对偶内点法。介绍了原-对偶内点法的基本思路和算法步骤,并用Matlab语言编写了关于原-对偶内点法的最优潮流程序。计算了14节点系统的发电成本,其结果表明原-对偶内点法对目标函数的优化效果更好,算法的中间量也能为调度提供合理的经济信号。
In order to protect the security and stability of the grid,with the current conditions,we propose a method of solving optimal power flow-the original-dual interior point method.Introduced the original-dual interior point method the basic ideas and steps of the algorithm,and use Matlab language on the original-dual interior point method of optimal power flow program.Calculated the cost of power generation 14-node system,the results show that the original-dual interior point method for optimization of the objective function better,the middle volume algorithm can provide a good economic signal for the economic dispatch.
