Supplied by medium-voltage-DC power source, the AC-DC hybrid microgrid derives a stable AC-DC system voltage which ensures the parallel-operation stability of the multiple converters. The distribution network is configured with energy router to build low-voltage AC-DC system voltage and provide power to the AC-DC loads. Under the premise of ensuring fault isolation of the AC and DC systems, energy router can achieve two-way power transmission of AC and DC power supply, which enhance the consumption of multi-source and improves the reliability of microgrids. A system topology of the low voltage AC-DC hybrid microgrid based on the universal energy router technology is proposed, and the port configuration and control mode of the energy router are optimized. The multi-source parallel control strategy is studied, which effectively improves the stability of multi-source parallel operation. Also the control strategies including primary regulation, secondary regulation and fast conversion of converter control modes, can effectively enrich the operation modes of the distribution network and optimize the consumption path of new energy sources such as photovoltaics and wind power.
