摘要:

以规模化储能为研究对象,在电力市场放开背景下,开展其参与电力现货市场的商业模式研究.首先,从国内外典型市场出清机制出发,分析日前市场及实时市场的出清方式、出清计算等过程,提出适应规模化储能参与现货市场的联合出清机制,包括投标方式、计费方式和出清方式等.其次,为充分发掘规模化储能的市场价值与其他附加价值,增强集群效应并解决储能容量闲置问题,提出适应规模化储能参与现货市场的商业模式,包括独立式(投资主体单一、服务模式单一),联盟式(投资主体多样、服务模式单一),共享式(投资主体多样、服务模式多样),并分析市场交易链中存在的博弈关系,量化电能价值、辅助服务价值以及其他附加价值.在此基础上,基于主从博弈构建不同商业模式下储能参与现货联合市场的双层出清模型范式.上层模型以储能为领导者、以储能收益最大化为目标参与市场竞争,下层模型以调度和交易中心为跟随者、以社会福利最大化为目标进行联合出清;最后,基于改进的IEEE30节点系统,以典型交易场景为例验证所提参与商业模式的有效性和可行性.

Abstract:

In this paper, large-scale energy storage system(ESS) is taken as the research object to conduct study of business models on the participation of ESS in electricity spot market with liberalization. First, based on the typical market clearing mechanism at home and abroad, the clearing method, clearing calculation process and so on in day-ahead market and real-time balance market are analyzed, and a joint clearing mechanism suitable for large-scale ESS to participate in the spot market is proposed, including bidding method, billing method and clearing method, etc. Then, in order to fully explore the market value and other added value of large-scale ESS, to enhance cluster effect and to solve the problem of idle ESS capacity, business models suitable for large-scale ESS to participate in the spot market are proposed, including independent (single investment entity, single service model), alliance (diversified investment entities, single service model), and shared (diversified investment entities, diversified service models) models. The game relationship in the market transaction chain is analyzed, of which the electric energy value, the ancillary service value, and other added value are quantified. On this basis, a bilevel clearing model paradigm for ESS to participate in the spot joint market of different business models is constructed based on the master-slave game. In the upper-level model, large-scale ESS is the leader to participate in market competition with the goal of maximizing profits, while the dispatching and trading center in the lower-level model are followers to jointly clear the market with the goal of maximizing social welfare. Finally, the validity and feasibility of the proposed business models are verified by taking typical transaction scenarios as examples based on the improved IEEE30 node system.

Key words: large-scale energy storage system (ESS), spot market, clearing mechanism, business model, game theory
