Active development of green energy and the continuous major problem in the world leads to serious issues related to the load demand. This issue requires particular strategies to be incorporated to maintain necessities of electrical power among green energy resources and the utility grid. This work presents a particular algorithm for power management in hybrid renewable energy system under a set of constraints, weather conditions and utility grid status. To manage the flow of power between the different loads (first, second and third load) and the multi-agents; (utility grid, green energy resources and storage units).
