【 摘 要 】

The Combination of large power grid and distributed power supply is recognized by electric power experts as the development direction of power industry, which can save energy consumption, improve the reliability and flexibility of power system. Therefore, it is of great value to study distributed power supply. According to the shortcomings of PI control gain at the fundamental frequency of small, poor control effect, introducing the band-pass quasi PR controller, and improve the algorithm in order to improve the control effect, and finally through the MATLAB simulation software to test the improved algorithm, verify the feasibility of the algorithm and accuracy.
