摘要
提出了一种确定机组组合的改进动态规划方法 ,称为插值动态规划算法。这是一种启发式方法 ,可以和其他的经济调度算法相结合 ,用以解决多种约束条件下的机组组合问题 ,特别是可以处理机组功率上升、下降速度约束 ,且考虑了机组的开、停机特性 ,并有效避免了“维数灾”问题 ,经实践检验是一种简单、有效的实用算法。
In this paper an improved dynamic programming method to determine unit commitment is proposed. This proposed method is also named interpolated dynamic programming algorithm. It is a heuristic method, which can be combined with other economic generation dispatching methods, to solve unit commitment problem under multi constraints, specially the unit ramp constraint. In this method the start up ramp and the shut down ramp of the units are considered, and the curse of dimensionality can be effectively avoided. The results of practical tests show that this algorithm is simple and effective.
