Energy Management Strategy and Configuration Optimization for Fuel Cell Combined Heat and Power System Considering Multi-Energy Flow Coupling Characteristics

This paper focuses on fuel cell combined heat and power (CHP) systems and conducts research on multi-energy flow coupling energy management strategy. By constructing a system-level operational simulation model, an energy management strategy based on the fluctuation characteristics of cooling, heating, and electricity loads as well as the peak-valley electricity price mechanism is formulated. The dynamic operation process of the system under typical operating conditions is simulated, and the coordinated control mechanism among fuel cells, electrolyzers, energy storage devices, and the power grid is clarified. Through the analysis of multi-energy flow coupling results, the significant advantages of the system in cooling-heating-electricity multienergy complementarity and multi-period collaboration are further verified, providing support for the efficient operation of the system. Finally, the system parameters under this strategy are matched and optimized by using particle swarm optimization algorithm with the goal of economic behavior. After optimization, the cost of the system is reduced by 3.92%.
