摘要(Abstract)：

峰谷分时电价是一种有效的价格型需求响应策略,合理的峰谷电价能为用户提供充足有效的价格信号,从而达到削峰填谷的目的。采用需求价格弹性分析用户的用电量随电价的变化情况,从而建立用户的分时电价响应模型。以峰谷差最小为目标,考虑保证用户利益且峰谷电价比在一定范围内等约束条件,建立峰谷分时电价的有约束非线性规划模型。设计分时电价的十进制编码方案,根据生存概率以轮盘赌方式对染色体进行选择复制,以随机概率的方式进行染色体的交叉变异,从而构造相应的遗传算法求解思路。分析该优化分时电价下的需求响应效果,并讨论需求弹性和峰谷时段的改变对优化结果以及需求响应的影响。算例分析表明该模型能有效改善负荷曲线,达到较好的需求响应效果。
