摘　　要：从分析备用与可靠性之间的关系入手,构建了计及可靠性约束的备用优化模型。该模型以系统总购电费用最小为目标,而系统备用的总量通过一组体现备用互补性的约束方程加以描述,以保证备用优化结果满足发电系统的N-1安全准则。结合算例进行仿真分析,验证了模型的合理性与有效性。Beginning with analysis of relation between reserve and reliability,this paper establishes reserved optimization model considering reliability which targets minimum electricity fee.The reserved total volume,described by constraint equation which reflects reserve complementary,guarantees that the optimization meets the requirement of N-1 safety criterion of generation system.Simulation analysis is conducted,combing examples,to verify the rationality and effectiveness of the model.
