Abstract

The traditional droop control has the advantages of low cost, easy to expand, easy to proportional load sharing and so on. But the micro-grid line impedance is resistive, which makes the output power coupling each other .The virtual impedance control strategy can help micro-grid converter to realize active power and reactive power decoupling but the large virtual impedance value will lead to the voltage drop of the system. This paper presents an improved droop control strategy with voltage feedback, which is a method to solve the problem of pressure drop after the introduction of virtual impedance. Simulation results are provided to verify the analysis and design.
