Abstract-This paper proposes an intelligent power management controller based on the fuzzy logic that integrates wind energy, solar energy, and grid with battery backup. This system is capable of exchanging power with the local grid.
The proposed fuzzy control strategy senses the continuous fluctuations in solar, wind power generation and battery state of charge. Then it calculates the load demand in order to make the best use of sources without any exact numerical model and obtain better reliability than that could be obtained by the conventional system. In this paper, a mathematical calculation is provided to evaluate the proposed Optimal Fuzzy Logic based smart Energy Management system which is more cost-effective than the others conventional systems like direct grid connected and renewable energy feeding system.
