The energy utilization system in husbandry park is a typical integrated energy system of electricity and heat. The coordinated utilization of the adjustable resources is an important means to promote the electrification, intellgence, and low-carbon level of husbandry park. This paper research an optimal scheduling strategy of electric-thermal coupling considering energy load aggregation transactions in husbandry park. Firstly, the scheduling organization process of adjustable resource aggregation transaction is constructed. Secondly, a two-stage optimal scheduling model is constructed. The first stage is the aggregation trans-action optimization of the adjustable resources in the husbandry park, and the second stage is the dispatching optimization based on the power trading results of the adjustable resources. Finally, an integrated energy system based on the improved power distribution system and heating system was constructed. The simulation and analysis results indicate that the proposed the strategy can tap the response potential of husbandry park electricity and heat resources through trading capability, reduce the energy cost and economy of husbandry park, and verify the effectiveness of the proposed method.
