| 摘 要： | 针对传统机组组合模型的种种不足,该文提出了一种考虑交流潮流约束及静态安全约束的机组组合模型,并给出了一种完整的并行化解法。该法借助于扩展拉格朗日松弛法和变量复制技术,将原问题转换为其对偶问题,并利用附加问题原理将对偶问题分解为动态规划和最优潮流(OPF)子问题。对于OPF子问题,采用鲁棒性好、收敛速度快的预测校正内点法求解,同时在求解过程中,采用并行处理技术。IEEE118节点及IEEE300节点仿真结果表明,该方法收敛性好,非常适合并行处理。

| Abstract: | A new parallel algorithm for unit commitment including AC power flow constraints is proposed. This algorithm employs a new augmented Lagrange relaxation method that involves the variable duplication technique and auxiliary problem principle to convert the primal problem into its dual problem,and obtain the separation structure of the Lagrangian function which can be decoupled into dynamic programming subproblem and optimal power flow (OPF) subproblem. Predictor-corrector interior point method is applied to ... |
