　　风电的随机波动性增大了系统调度的难度，将需求响应融入传统发电日前调度计划，将风电备用成本纳入目标函数，同时增加了正负旋转备用约束。以基于消费者心理学的分时电价用户响应原理预测负荷曲线，将可中断负荷作为部分系统备用，建立面向大容量风电接入考虑用户侧互动的系统日前调度模型和运行模拟模型。综合考虑发用电侧资源，将分时电价和可中断负荷这两种需求响应措施融入同一模型，用于应对风电的反调峰特性和间歇性。采用蒙特卡洛算法模拟多种风电出力的情况，评估考虑用户侧互动前后系统的弃风量和电力不足情况，并分析风电渗透率和弃风量、电力不足量的关系。IEEE24节点算例验证说明了本文用户侧互动调度模型的作用，可以起到有效降低发电成本，提高风能利用效率和风电容量利用水平的作用。

The stochastic fluctuations of wind increase the difficulty in operating scheduling in power system. This paper established a generation scheduling model and operation simulation model considering demand response in large-capacity wind power integrated system. In the model reserve cost for wind power was incorporated into objective function and up spinning reserve and down spinning reserve were considered. Load curve was predicted according to user response principle based on consumer psychology and interrupted load acted as part of system reserve. The effectiveness of TOU and IL was integrated into one model on account of coordinating generate and demand side, which could respond to characteristic of negative peaking load shifting intermittency of wind power. The wind energy curtailment and loss of load before and after considering demand side response under varieties of wind power outputs were estimated by Monte Carlo simulation. The relationship between wind power penetration and wind energy curtailment and the one between wind power capacity and loss of load were presented in this paper. The simulation on IEEE 24-bus system indicated this model can decrease the generating cost effectively and increase utilization ratio and levels of capacity usage of wind power.
