AB Thermal energy storage systems (TESSs) enhance multi-energy microgrids (MEMGs) operationby optimizing energy management. While previous research primarily focused on optimizing theMEMG operation using static MEMG models, this paper analyzes the dynamic impact of TESSon a grid-connected residential MEMG. This includes a photovoltaic plant, an electrical battery,and a hydrogen system with an electrolyzer, a fuel cell, and hydrogen tank. The thermal subsystemincludes a gas boiler, a micro-combined heat and power (CHP) unit, an electric boiler, and a TESStank. A novel intelligent control architecture based on fuzzy logic, model predictive control, andnonlinear optimization is presented to control the MEMG. Simulation results with TESS reveal abalanced heat production and demand, and improved temperature control. The integral timesquared error (ITSE) is reduced by 91 % for the hot water circuit control and 81% for the overallthermal balance of the MEMG. The improved control scheme also reduces the gas consumption,with a reduction of 12.44% for the gas boiler, 1.81% for the CHP, and 8.66% in total, leading inturn to reduced operational costs (by 6%) and CO2 emissions (by 8.37%) compared to the MEMGoperation without a TESS under the same control scheme.
