Abstract

The combination of two inverters will produce circulation, which will seriously damage the inverter. At present, a lot of research on the parallel inverters can solve this problem, and Droop control is the most common method. However, there are few reports on how to parallel multiple inverters, and how to connect multiple inverters to the grid after parallel connection. This paper deduces the principle of Droop control, constructs a new multi-inverter parallel system based on Droop control or VSG control, uses MATLAB simulation to verify the system, proposes a new multi-inverter parallel parallel grid connection equivalent model, and finally proves the rationality of the model through MALTAB simulation.
