Abstract
AC-DC hybrid microgrid has advantages of both AC/DC power supply and consumption system, and can meet the access of a variety of distributed power sources, energy storage units and loads. This study focuses on the application mode of ac-DC hybrid microgrid based on energy router.In terms of application mode research of hybrid microgrid with multi-port energy router, topology and coordination control of hybrid microgrid are studied and simulated in detail for typical application scenarios of large industrial enterprise parks.For large industrial enterprise parks, the hybrid microgrid topology of optical storage industrial enterprise parks is constructed to realize the common DC access of distributed power supply, electric vehicles and energy storage.The coordinated control strategy of energy router to controllable resources in the park under multi-mode grid connection is developed.Through the simulation experiment built in DIgSILENT/PowerFactory software, it is verified that the proposed scheme can significantly reduce the loss of industrial enterprise park and reduce the impact on distribution network.
