摘要
机组组合(UC)是电力系统经济运行的重要内容之一.根据UC约束特点将机组组合问题分解为单机多时段和多机单时段问题.基于蒙特卡洛(MC)优化法原理,解决单机多时段的启停问题及最后过滤比较找出最优可行解;利用运行费用可导性,解决了爬坡约束并得出多机单时段下的最优解.最后在Matlab 6.1下通过算例验证了该方法的可行性.
Unit commitment (UC) plays an important role in the economic operation of electric power system. This paper treats UC as a two-phase problem: single unit for multiple periods and multi-unit for single period . In line with Monte Carlo (MC) optimization method, this paper solves the constraints of start-up and stop, and reaches the optimal solution. The operation cost derivative is used to represent the AFLC factor and gets the optimal solution of a single period. Finally the example is employed to show the feasibility on Matlab 6.1.
