Study on the Optimization of AC/DC Hybrid Micro-grid System Based on ILC Power Control

In order to improve the power quality of AC/DC hybrid micro-grid and the response characteristics when the load changes, an AC/DC micro-grid containing wind turbine, photovoltaic power generation unit, fuel cell and energy storage equipment is established, and the ILC power control strategy is used to optimize the system. The transient responses of micro-grid to load transformations under different control strategies are simulated and compared, which verify the superiority of ILC power control strategy and provide a simulation platform for the further study of the micro-grid.
