Depending on the time scale and the function, a three-layer hierarchical coordinated control framework of microgird is presented. The framework is applied to a typical micro-grid, which involves both the internal combustion engine CCHP system with the synchronous generator and other inverter distributed generation(DG)systems. For the typical micro-grid, specific coordinated control strategies are proposed. An additional controller based on status-followed control is utilized in the switching controller to ensure the smooth transition of the battery’s output power during the control mode switching. The simulation results of the micro-grid under different operating modes and mode switching processes show the effectiveness of the proposed coordinated control strategies. Furthermore, the effects of the CCHP system in the micro-grid coordinated control are also analyzed.
