摘　　要：月度发电计划的复杂性和求解规模,使得月度机组组合方案的制订变得十分困难。文中基于兼顾计算性能和月度计划关键需求的原则,通过时段简化和电力电量解耦,建立了以电量进度偏差最小为目标的月度安全约束机组组合(SCUC)模型,并采用混合整数规划(MIP)算法加以求解。实际系统算例测试验证了该模型的有效性。The complexity and solving size of monthly generation plan makes it difficult to optimize monthly unit commitment.Based on the principle of simultaneously considering calculation performance and key demands on the monthly plan,a monthly security constrained unit commitment（SCUC） model with minimum energy deviation as the objective is developed by period simplification and power-energy decoupling.The model proposed is solved with a mixed integer programming optimization algorithm.Test results for an actual provincial system show the validity of the model.
