摘要：
To improve the dynamic performance of the energy storage converter and the adaptability to the micro-grid, a method of predictive direct power control of the energy storage converter model is proposed. The discrete output model of the energy storage converter is used to predict the next output power of various switching states, and the switching state with the minimum deviation of the reference power is selected to realize the high dynamic operation of the energy storage converter. Aiming at the harmonic and unbalance of the micro-grid voltage, the quadratic generalized integrator is used to extract the voltage fundamental frequency normal sequence component, and the energy storage converter is controlled to be stable and its adaptability to the micro-grid is improved. In the environment of MATLAB/Simulink, the direct power control method of energy storage converter model is simulated and analyzed, and the experiment platform of energy storage converter is designed. The results show that this method can improve the power response speed and overshoot, and it can be stable in the harmonic and unbalanced state of the micro-grid.
