摘　　要：为了规范电力市场中的信息披露行为,电力监管机构会要求电力调度交易中心披露大量市场信息。从数据学习的角度来看,海量的市场交易信息不但无法提供有效的市场交易信息,反而可能导致信息灾难问题。为此,文中对电力市场信息分类方法、披露原则问题进行了定性和定量研究。通过对电力交易计划最优判据的研究,提出了交易计划的关键信息集合的概念和交易公平性判据。关键信息集合是用来判断电力交易合理性的最小信息集合。利用关键信息集合概念确定电力市场披露信息种类,能够大大减少信息披露中的冗余信息,避免出现信息灾难。研究还表明,市场出清价格在判断交易计划公平性时价值不大,而节点边际电价包含了关于电力交易的大量信息,应该成为电力市场信息披露中最重要的数据之一。In order to standardize the information releasing behaviors, electricity regulatory authorities require the power dispatching center and the electricity trade center to release lots of market-related information. From the aspect of data learning, huge mount of data might not provide valuable information of electricity trade. In contrast, it possibly causes the data disaster. This paper quantitatively and qualitatively studies the category method and releasing criteria of electricity market information. Based on the optimal criteria of market based electricity trade, the concept of key information set and the fairness criteria of electricity trade are proposed. The key information set is the minimum data set required to check the fairness of electricity trade. Using the key information set, redundant data can be eliminated from released information to avoid the data disaster. Numeric studies also show that market clearing price is less valuable than nodal marginal price, which contains lots of electricity trade information and should be one of the most important parts of released information in electricity market.
