The coordinated utilization of the resources of generation-grid-load-storage is an important means to promote the efficient operation of the regional integrated electric and heating system (RIEHS). This paper proposes an optimal dispatching method for RIEHS considering aggregation and transaction of generation-grid-load-storage. Firstly, the RIEHS dispatching framework is constructed, and the RIEHS dispatching organization process considering aggregation and transaction of generation-grid-load-storage is designed. Secondly, a two-stage optimization dispatching model of RIEHS is established. The first stage is the optimization of the aggregation and transaction of the resources of generation-grid-load-storage by the virtual power plant. The second stage is RIEHS dispatching optimization based on the transaction results of the resources of generation-grid-load-storage. Finally, based on the improved IEEE 33-node power distribution system and the 32-node Bali heating system, a RIEHS with three virtual power plants is constructed for simulation and analysis. The results show that the method proposed in the paper taps the response potential of user-side resources through transaction means, improves the operating income of virtual power plants and the economy of system operation. The effectiveness of the dispatching method has been verified.

Key words: regional integrated electric and heating system (RIEHS), generation-grid-load-storage, aggregation and transaction, virtual power plant (VPP), optimal dispatching
