Novel configuration and controlling method on islanded microgrid in order to share active and reactive loads on energy supply units without voltage and frequency drop

Configuring and novel controlling method on islanded micro grid in order to share active and reactive load on energy supply units are represented in this article. In a micro grid which is supplying its network load in islanded mode, stable operation of micro grid and sharing load on energy supply units are necessary. Therefore Droop control method is using as an effective method for load sharing on energy supply units. This method, in addition to hardening access to stable network during the load variations, causes voltage and frequency droop within the network. In this article the problem of voltage and frequency droop has been solved by presenting a new structure in micro grid configuration which consists distributed generation and power-electronic converters. As a result, access to a stable network during load variations will be achievable. Furthermore, active and reactive load sharing on energy supply units will be done. Simulation results of a micro grid with configuration and suggested controlling structure in Matlab/Simulink are the validation of proposed method in this matter.
