Fuzzy logic-based energy management system for grid-connected residential DC microgrids with multi-stack fuel cell systems: A multi-objective approach

Hybrid energy storage systems (HESS) are considered for use in renewable residential DC microgrids. This architecture is shown as a technically feasible solution to deal with the stochasticity of sources, however, complexity its design and management increases inexorably. To address this problem, paper proposes fuzzy logic-based system (EMS) grid-connected microgrids HESS. It hydrogen-based HESS, composed batteries multi-stack fuel cell system. The proposed EMS based on multivariable multistage logic controller, specially designed cope multi-objective problem whose microgrid performance terms efficiency, operating costs, lifespan considers power balance prediction, degradation subsystems, well main electricity grid costs. article assesses developed respect three reference EMSs present literature: widely used dual-band hysteresis two model predictive control. Simulation results show an increase from technical economic point view.
