Abstract: The new round of power system deepening reform in China is in full swing.It has become an important task for the next step to speed up the construction of electricity spot power market.Based on the real constraints on Chinese electricity market construction,the core objectives and pattern selection issues of the spot market construction are discussed.Based on the idea of"the formation of competitions among generations and consumers",a construction path design of the spot market is proposed.To seize the opportunity of rapid starting,a"three-stage"construction path of the power spot market is designed.A set of implementation,decomposition and settlement methods of the medium-and long-term electric quantity transactions to work in the spot market is proposed,accomplishing the compatible and coordinated operation of the spot market and long-term power transactions.At last,the paper gives a series of case studies of the proposed market mechanism,from two perspectives of provider and consumer.The different settlement characteristics of consumers with various power utilization behaviors are demonstrated.The results show that the proposed method is beneficial to the users who respond to the system peak-shaving demand and realize optimal allocation of incentive compatible resources.
