摘  要:现货市场是现代电力市场体系中不可或缺的环节之一,由于在电力市场化的环境下辅助服务市场在一定程度上与现货市场中的主能量市场存在耦合关系。因此,为了有序地推动电力现货市场的建设与发展,必须构建调频、备用、调压市场并研究其与现货市场之间的衔接问题。该文立足于当前国内电力市场建设的情况,对国内未来现货市场与辅助市场的衔接进行规划与设计。

Abstract: The spot market is one of the indispensable links in the modern electricity market system. In the electricity market-oriented environment, the auxiliary service market is to some extent coupled with the main energy market in the spot market. Therefore, in order to promote the construction and development of the power spot market in an orderly manner, it is necessary to build a frequency modulation, reserve, and voltage regulation market and study the connection between it and the spot market. Based on the current domestic power market construction, this article plans and designs the connection between the domestic spot market and the auxiliary market in the future.

Key Words: Electricity market; Spot market; Ancillary service market; Connection mechanism

1  辅助服务市场与现货市场的差异

在交易组织和交易方式方面,华北调频辅助服务市场以省网(控制区)为单位开展,报价周期根据电网实际调频需求容量的变化确定,采用集中竞价、统一出清、边际价格定价的方式开展;华北地区省网调峰市场采用日前集中竞价、日内统一出清的日内市场方式开展。山西省调频辅助服务市场采用集中竞价、边际出清、统一价格的方式组织;深度调峰交易采用双向报价、集中竞争、滚动出清、统一价格结算的方式。山东调频调峰辅助服务市场为日前集中竞价,日内按照“价格优先、时间优先、按需调用”原则调用的方式组织。湖南抽水蓄能辅助服务专项市场采用双边协商交易和要约招标两种方式进行交易。

当前所说的电力辅助服务市场还不能称之为真正的市场。各地现行的辅助服务市场中,一般都是采取卖方报价、竞价,调度方根据价格由低到高依次调用,最后将费用平均分摊给纳入辅助服务补偿机制范畴的其他发电商和用户[1]。……
