摘要
机组组合问题是在调度周期内满足各种运行约束条件的前提下,通过合理地控制机组的开、停状态以实现总运行成本最低目标的问题。本文以电力系统机组组合为研究对象,对优先顺序法与动态规划法在机组组合中的应用进行了研究和探讨,并根据他们的优缺点,建立了改进的算法—基于优先顺序法的动态规划法。
On the premise of meeting variety of conditions in the running cycle,unit commitment is to achieve the lowest total operating cost by controlling the running or suspending status of units rationally.With study of unit commitment in power system,some applications about the methods of priority list and the dynamic programming are discussed in this paper.It establishes an improved algorithm,that is,dynamic programming method on the basis of using the priority list according to these two methods’ respective advantages and disadvantages.
