摘要(Abstract)：

针对主动配电网中因通信异常导致的控制扰动问题，提出一种适应非理想通信环境的主动配电网柔性负荷建模与控制方法。在非理想的通信环境中，建立柔性负荷混合系统控制模型，引入信息时延参量推导含时变信息的状态转移矩阵，并提出非理想通信环境下柔性分布式负荷的混合系统建模与主动配电网控制优化方法。在某冷库制冷负荷算例中对所提方法进行仿真验证，综合比较所提方法与未考虑信息时延的传统控制方法在功率波动、总体能耗等方面的表现。实验结果表明，所提方法有效抑制了信息时延导致的控制扰动，实现了平抑馈线功率、降低总体能耗的目的。
Given the control perturbations in active distribution networks(ADNs) due to communication anomalies, a flexible load modeling and control method for active distribution networks adapted to non-ideal communication environments is introduced. In the non-ideal communication environments, a hybrid system control model of flexible loads is established, the information time delay parameter is introduced to derive the state transfer matrix containing time-varying information, and a hybrid system modeling and active distribution network control optimization method for flexible distributed loads in the non-ideal communication environment is proposed. The proposed method is simulated and verified in refrigeration load calculations within a cold store, and the performance of the method is compared with that of the traditional control method without considering the information delay in terms of power fluctuation and overall energy consumption. The experimental results demonstrate that the proposed method can mitigate the control perturbations arising from information delay, smooth out feeder power, and reduce the overall energy consumption.
