In order to realize the seamless switching of micro-grid operation mode, a hybrid control algorithm considering energy storage (ES) grid-connected inverter is proposed in this paper. Aiming at the characteristics of the hierarchical control structure of inverter, firstly, the two-degree of freedom control principle, the current predictive control model and modified droop control phase are combined, and three kinds of controls are applied to different layers of the inverter. Thereinto, together with current prediction model controller is adopted to replace PI controller and PWM regulator in the current inner loop of control layer. The principle of two-degree of freedom is adopted to construct the inverse model of the controlled object in the voltage outer loop of control layer. And based on the current model predictive control of inner current loop, the unit transfer function of the control layer is realized. Then, the influence of harmful disturbances on energy storage control system can be eliminated. For the application layer of ES system, the improved droop control with voltage and frequency as feedback is used to realize the voltage and frequency regulation of islanding micro-grid. And because the control layer can be used as the shared layer of ES system, during the switching process of micro-grid operation mode, the transient surge current and bus voltage distortion rate of micro-grid can be significantly suppressed. Finally, the correctsness and effectiveness of the proposed hybrid control algorithm are verified by MATLAB/Simulink simulation system.
