New power sharing control method in an islanding microgrid for enhanced utilization of distributed generators

Abstract:   (5214 Views)

In this paper a new power sharing control method is proposed for islanding microgrids. With regard to low dynamic distributed generators like fuel cells, microgrid capability is enhanced to face the different load scenarios. In the new method there is not the need for energy storage devices like batteries and super capacitors in coordination with low dynamic energy resources. So the productivity of the installed capacity is enhanced. Any change in the load is automatically detected by the proposed method and the controller manages the dynamic distributed generator power in its transient time. Back to back voltage and current controllers are also embedded beside power controller to enhance the transient stability of the microgrid in sudden load changes. In order to evaluate the new method, a sample microgrid is considered. Simulation results show the proper power sharing among the generators while satisfying the frequency stability of the system. Technical and economical comparison show the effectiveness of the proposed power sharing method with respect to the conventional methods.

Keywords: Distributed generation, power sharing, islanding microgrid, voltage and current controller
