基于logit离散选择模型的考虑需求响应含风电系统优化调度

Optimal Dispatching under Grid-Connection of Wind Power Considering Demand Response Using Logit Discrete Choice Model

风电因为其本身具有波动性、间歇性等特点,风电并网增加了传统电力系统优化调度的难度。引入需求响应,重新整合用户侧资源,能有效提高风电并网的经济性。因此,建立考虑需求响应的风电并网优化调度的新模型。首先建立基于logit离散选择模型的用户对电价菜单的自主选择模型,用户选择不同菜单电价并作出相应的负荷削减。然后建立考虑用户菜单电价选择和可中断负荷调用的需求响应含风电电力系统优化调度模型,将可中断负荷调用容量作为系统部分旋转备用容量。目标函数在传统含风电系统优化调度模型基础上,加入可中断负荷调用成本。最后,利用蛙跳简化粒子群算法对改进后含风电场的IEEE-RTS24系统进行分析验证,结果证明本文所建立模型的正确性和有效性。

Wind power increases the difficulty of the opti- mal dispatching in the traditional power system because of its volatility and intermittence and so on. Introducing demand re- sponse and integrating the user side resources can improve the economy of the optimal dispatching of wind power integrated systems effectively. To this end, a new model of the optimal dispatching under grid-connection of wind power considering demand response is built.
