To address the low efficiency and high pollution associated with fossil-energy-dominated energy use in rural industrial parks, a park-level integrated energy system （PIES） model is established based on the source-load characteristics of rural parks. To promote renewable energy accommodation and biomass utilization, a power-to-ammonia system （P2A） and a biomass anaerobic fermentation gas production system （AF） are introduced into the PIES and modeled in detail. Considering the influence of anaerobic fermentation temperature on gas production rate, the waste heat from the P2A system is delivered to the AF system to construct a P2A-AF coupled system, thereby improving system energy efficiency and economy. On this basis, detailed carbon emission modeling is carried out for the main energy-use processes of the PIES, and carbon emission costs are incorporated to establish an optimal dispatch model with the minimum total cost as the objective. The simulation results show that the proposed system can improve energy economy by 31.56%, increase the local accommodation rate of renewable energy by 34.92%, and reduce total carbon emissions by 3.58%.
