A decentralized coordinated controller for load sharing in a microgrid with renewable generation

The aim of this paper is to introduce a control algorithm for load sharing in a microgrid with renewable generation mix. A decentralized coordinated power sharing control scheme is proposed considering both resistive and inductive line parameters, dynamics of the sources, weather condition, and multiple distributed energy resources (DERs). In this paper, a central power management unit is developed that specifies the reference real and reactive power generation for each distributed generator (DG) by considering the load demand and the generation availability. Local controllers are responsible for controlling the voltage and angle to inject the required amount of power into the grid. Simulation results show the viability of the proposed control scheme.
