| 摘 要： | 随着智能电网的发展,用户的需求响应能力进一步增强,对发电检修的协调安排带来了新的影响。提出了机组检修协调意愿费用曲线,建立了考虑需求价格弹性的发电检修决策协调模型。在此基础上,深入分析市场环境下中长期发电检修决策对短期市场供求关系及出清价格的影响。建立了用户电力需求随电价而弹性变化、最终受中长期发电检修决策影响的函数关系;通过函数分段参数的讨论与约束的合并变换,将非线性混合整数规划模型转化为线性整数规划模型;根据智能电网下不同需求响应场景模拟,评估分析了需求弹性对发电检修决策产生的影响与效益。

| Abstract: | With the development of smart grid,demand response capacity is further enhanced,which influences the coordination of unit maintenance scheduling.Maintenance coordination cost curve is proposed,and unit maintenance coordination model is established considering the elasticity of demand price.On this basis,influence of long-term maintenance scheduling on short-term market demand-supply relationship and further on market clearing prices is analyzed.The function of load demand elastically changing with price and... |
