Abstract: With the increasing penetration of renewable energy in the power system, energy storage is widely used to alleviate volatility. However, traditional energy storage has disadvantages of small distribution range and high cost.Generalized energy storage is different from traditional energy storage equipment. Heat storage, cold storage and flexible load are also regarded as energy storage resources, and their flexibility and wide distribution are used to realize the complementarity of distributed resources. In this paper, an energy storage sharing transaction model considering generalized energy storage is proposed. In the model, generalized energy storage such as building thermal inertia, ground source heat pumps and hot water pipelines are studied, and the transaction mode of bilateral auction is used for energy storage sharing. In this energy storage sharing mode, the buyer and seller of energy storage bid, and the intermediate auctioneer determines the final winning situation according to the bidding price. Finally, through an example, the shared transaction of generalized energy storage is analyzed, and it is found that the time-shift characteristics of energy storage can improve social benefits, and the market power of the transaction participants will affect the final shared bid winning situation.
