| 风电建模为多状态发电机组，以风电停运率考虑风电功率预测误差的不确定性，在基于消费者心理学的可中断负荷响应模型的基础上，综合评估含有风电、可中断负荷不确定性的系统可靠性指标。建立了日前备用协调优化模型，优化模型以满足一定供电可靠性为前提，同时优化可中断负荷备用和发电机备用容量，在24个时段的范围内研究计及风电不确定性下可中断负荷作为备用资源的积极效果。算例结果表明，引入风电后，系统对可中断负荷的需求有所增加，可中断负荷作为一种灵活的调控手段，在应对风电不确定性、降低系统运行成本上有积极意义。 |

| In this paper, wind power is modeled as a multi state generator, and the uncertainty of wind power prediction error is simulated by wind power outage rate.Based on the model of the interruptible load response based on the consumer psychology, this paper comprehensively evaluated the reliability index of the system which contains wind power and the uncertainty of the interruptible load.In this paper, a model for the coordination and optimization of the former days is set up.In order to meet the reliability of certain power supply, the optimization model can optimize the interruptible load and generator reserve capacity simultaneously.And in the 24 period of time, the positive effect of the interruptible load as a spare resource is studied under the condition of wind power uncertainty.Simulation results show that the demand of interruptible load for the system can be increased because of the need to stabilize the fluctuations of wind power after the introduction of wind power.As a kind of flexible control method, the interrupt load has positive significance in dealing with the uncertainty of wind power and reducing the operating cost of the system. |
