Abstract

This paper explores the power distribution problem of parallel-connected inverter system which supplies auxiliary power for railway facilities. We propose a droop control method which facilities power distribution and restrain of voltage drop by tracking the average power control command by adjusting the virtual impedance. The performance of proposed droop method is verified by the PSIM simulation.
