AB The design of energy management systems (EMS) and dynamic control systems of multi-energymicrogrids (MEMGs) combining diverse energy vectors (electricity, heating/cooling, and hydrogen)has not been extensively explored. This paper presents a novel hybrid EMS combining fuzzy logicand model predictive control to optimize energy dispatch and reduce grid dependency in a gridconnected MEMG. It comprises for a photovoltaic power plant, a battery, an electrical residentialdemand, a fuel cell, an electrolyzer, a hydrogen tank, a gas boiler, an electric boiler, an absorptionchiller and thermal residential demand. The synergy among energy vectors is achieved by adjustingthe thermal component operation based on renewable production and storage levels. The findingsshow a notable decrease in gas (by 2.82%), electric boiler (by 18.75%), and absorption chiller (8.91%)usage compared to a conventional states-based EMS. The efficient energy dispatch leads to a 9.56%reduction in operational costs, and a 2.82% decrease in the CO2 emissions. Additionally, there is anincrement in the levels of state of charge of the electrical battery (by 21.43%), hydrogen level (by4.8%), and state of energy (by 18.85%). The results probe the adaptability and resilience of thesuggested EMS in effectively managing multiple energy vectors.
