Abstract:With the development of low voltage microgrid theory and practical technology, the power distribution control strategy among different capacity and different types of inverter power supply in low voltage microgrid has become one of the key technologies in microgrid research. This paper first analyzes the difference between the commonly used P-F/Q-V droop control and the P-V/Q-F droop control. Secondly, it analyzes the main reason of the power distribution deviation between the multi-inverter power supply. The key points are summarized in this paper. Finally, the different power distribution control strategies are compared and analyzed, and their advantages and disadvantages are compared to promote the development of low voltage microgrid.
