A modeling and optimal control method of flexible load in the active distribution networks in non-ideal communication environments

Abstract

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.
