摘　　要：随着电力系统中新能源渗透率的不断提高,储能被广泛应用于平抑新能源波动,促进新能源消纳。但传统储能存在分布范围小、投资成本高等缺点,广义储能将储热、储冷以及灵活性负荷视为储能资源,具有灵活可靠、分布广等优点,能够实现分布式资源的互补互济。基于此,提出了一种考虑热惯性的广义储能共享交易模型,计及了建筑物热惯性、柔性负荷、热水管道等广义储能,并采用双边拍卖的交易机制来进行储能共享。所提储能共享机制中,储能买家与卖家各自进行投标,中间拍卖商根据投标价格决定最终中标情况。最后,基于算例分析了广义储能的共享交易情况,研究发现储能的时移特性能够提高社会效益,交易参与者所含的市场力将会影响到最后共享的中标情况。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.
