Modeling and simulation for the power sharing of micro-grid inverter

Abstract

The problems of power sharing and loop current in parallel inverters situation will affect the operation efficiency of micro-grid. The model of two parallel inverters in the micro-grid island mode is built to test the power sharing droop algorithm and the control system. Using MATLAB/Simulink, the loop current and the power sharing results are analyzed. Conclusion shows that the different system parameters which affect the power sharing will play an important part in system design.
