摘要(Abstract)：

针对持续增大的负荷造成峰谷差增大以及大规模新能源并网给电力系统安全、稳定运行带来的一系列问题,基于节点电价进行了需求响应策略研究。首先,建立了含风电场的最优潮流模型,并采用跟踪中心轨迹内点法进行求解。然后,以最优潮流模型中潮流方程对应的拉格朗日乘子作为节点电价,提出了两阶段负荷需求响应模型,并将该模型应用于改进的IEEE-30节点测试系统。算例表明:两阶段负荷需求响应能够降低用户侧的节点电价,减少发电侧的燃料费用,充分利用风电资源;在一定程度下,用户侧参与需求响应能够将高电价节点的负荷转向低电价节点,并且参与需求响应的容量大小决定需求响应的程度。

关键词(KeyWords)： 节点电价;需求响应;风电场;最优潮流;跟踪中心轨迹内点法
