The cooperative optimization operation strategy of agricultural multi-park integrated energy system is considered

The structure of rural energy grid is weak, the energy regulation capacity of individual eco-agricultural park IES is limited, and the imbalance of energy supply and demand is easy to occur during peak load hours. In view of this, the multipark cooperative optimization operation strategy of multi-energy complementation in rural areas is proposed. Firstly, based on the multi-energy coupling relationship and system structure of IES in eco-agriculture multi-parks, mathematical models of biomass gas production link, multi-energy conversion coordination link and agricultural demand response link were established. Secondly, considering the constraints of energy equipment operation within each park and energy transmission between parks, and aiming at the lowest total daily operating cost and minimum carbon emission of the system, the IES collaborative optimization model of eco-agriculture multi-park was constructed and solved. Finally, based on three independent eco-agricultural parks IES in a southern province, the ecological agriculture multi-park IES was simulated. The calculation results show that the total operating cost of the system is reduced by $1.43 \%$, and the total carbon emission is reduced by $7.3 \%$
