With the growing energy demand in modern agricultural parks and the pursuit of sustainable development, achieving efficient, economical, and environmentally friendly operations has become an urgent issue. To this end, an optimization scheduling method for multi-energy systems in agricultural parks based on game cross-efficiency evaluation is proposed to enhance the operational efficiency of multi-energy system units. First, a biomass combined heat and power (CHP) model is established considering the energy characteristics of biomass fuels. At the same time, a hydrogen production-storage-utilization model is developed taking into account the properties and energy features of hydrogen. Subsequently, a game cross-efficiency evaluation model is constructed based on cross-efficiency, through which the efficiency values of each multi-energy unit are calculated according to the evaluation indicators. Then, by incorporating efficiency into the objective function together with system operating cost and environmental cost, an optimization scheduling model is formulated and solved using the CPLEX solver. Case study results demonstrate that the proposed strategy effectively enhances the operational efficiency of multi-energy system units.
