Improved fuzzy controller design for battery energy management in a grid connected microgrid

An improvement of fuzzy logic controller strategy for a grid-tied domestic microgrid is presented. The fuzzy logic controller takes onto account the microgrid power flux trend in order to minimize the power profile exchanged with the main grid while preventing at the same time the battery life time against deep cycles of charging and discharging. As well as in previous work, the fuzzy logic controller is designed to minimize a set of quality indices. The benefits of the new approach are highlighted through numerical simulations using real generation and consumption measured data.
