Abstract:In microgrid, connecting multiple bidirectional interface converters in parallel can improve the power exchange capacity on both sides of microgrid, but it is difficult to control microgrid effectively because of the power adaptive control problem of multiple bidirectional interface converters in parallel. After research, it is found that access to energy storage system can buffer the power fluctuation of microgrid and reduce the difficulty of power control of microgrid. In order to ensure the stable operation of microgrid and improve the accuracy of power adaptive control, a power adaptive control method of hybrid energy storage multi-microgrid based on edge calculation is proposed. Based on edge computing technology, this study analyzes the structure of hybrid energy storage multi-microgrid and constructs an automatic management platform for hybrid energy storage multi-microgrid. On this basis, by controlling the real-time voltage of the bus, frequency regulation is achieved, the stability of the interface converter is enhanced, and the scheduling and control of power interaction between the hybrid energy storage multi microgrid is completed. Integrating energy storage systems into hybrid microgrids, power exchange control and autonomous power frequency division adaptive control are used to achieve power adaptive control of hybrid energy storage multi microgrids. The experimental results show that the proposed method has a good power control effect on the hybrid energy storage multi microgrid, with a small error in active power control. It can effectively ensure the stable operation of the hybrid energy storage multi microgrid and improve the accuracy of power adaptive control.
