An important issue of microgrid is to share the load demand, the structure of the research. Two parallel inverters with load system are presented. The paralleled inverters need to work in grid-connected mode and stand-alone mode, and to switch seamlessly between the two modes. For a networked microgrid configuration with linear and nonlinear loads, the reactive power sharing is more challenging. For improvement of reactive power sharing and control in networked microgrid, a control method is introduced to reduce reactive power sharing errors by Droop control method is a widely used technique for achieving load sharing in microgrid applications. To achieve load sharing between parallel inverters, this control strategy combines frequency and voltage droop method and inverter voltage regulation control scheme. The droop methods are introduced to share real and reactive power in microgrid. The improvement of the droop control is made to obtain a more stable voltage and better load sharing between two parallel inverters. The performance of the control strategy is verified in simulation using Matlab/Simulink. To solve the power sharing control issues, the particle swarm optimization with the frequency-voltage droop control methods have been proposed. The real and reactive power are developed. In order to improve the stability of the microgrid system.
