In this paper, a small signal model based on droop controller is established for the self-synchronous voltage source parallel system. The influence of droop coefficient on system stability is analysed, and the constraint conditions of droop coefficient are given. Based on the analysis of the parallel system of self-synchronous voltage source inverter, a multi-machines parallel control scheme of self-synchronous voltage source inverter is formulated. The model and test platform are built to carry out the parallel simulation and experimental verification of distributed line impedance parameters. Simulation and experimental results show that the proposed control strategy can achieve good dynamic and steady-state power sharing.
