摘要:
基于我国南方区域现有的省间中长期电力交易的特点,针对当前省间仅开展中长期交易且标的为月度电量、部分省内开展现货交易的市场建设阶段,提出一种考虑不同交易组织周期的、时序递进的省间交易组织机制实现方案,并实现标的细化至分时曲线。引入交易级别的概念,明确下一级别交易开市前需确定上一级别交易交割电量作为边界的基本原则,并设计各级交易组织的衔接机制和工作流程。提出交易执行偏差处理方式,以及按照事前、事后2类偏差分别定价的结算定价方法,明确两级交易组织间的结算关系。

Abstract:
Based on the characteristics of current inter-provincial medium-and long-term power transaction in Southern China, aiming at the market construction phase that only medium-and long-term transaction is carried out between provinces with monthly electricity quantity as the target and spot transaction is carried out in some provinces, a realization scheme of inter-provincial transaction organization mechanism is proposed considering different transaction organization cycles and progressive time series, and the target is refined to the time-sharing curve. The concept of transaction level is introduced, and the basic principle that the transaction volume of the previous level is taken as the boundary before the opening of the next transaction level is determined, and the linkage mechanism and work process of transaction organization at each level are designed. A dealing way of transaction execution deviation and a settlement pricing method that pricing respectively according to the pre-and post-deviations are proposed, and the settlement relationship between two levels of transaction organization is determined.
Key words:  two-level transaction  medium-and long-term transaction  transaction sequence  deviation price  deviation handling
