Abstract

Abstract : The time delay caused by the communication network will influence the load frequency control (LFC) of the power system including multiple microgrids. A multi‐area power system consisting of multiple standard microgrids connected with tie lines is built in this study. Then the LFC equivalent model is constructed based on the proposed system considering the time delay. After that, a coordinated controller based on the model predictive algorithm is designed to deal with the load disturbances and the fluctuation of the wind power with communication delays in the LFC model. Case studies based on a multiple delays LFC system demonstrate the effectiveness of the proposed load frequency controller comparing with the conventional proportional integral load frequency controller.
