摘要
市场力是阻碍电力市场正常运行的最大因素之一,美国加州电力市场中的部分发电商行使市场力哄抬电价,在一定程度上导致了该州电力危机的发生。国内外对市场力判别方面的研究早已进行,但至今仍缺乏较为明确直观的方法。传统方法中,一般根据市场集中度来分析市场力,本文改变从发电侧根据机组所占份额来分析市场力的这一做法,试图从负荷侧根据线路对负荷的供电情况来进行分析,并提出一种简单可行的市场力判据。
Market power is one of the main contributors that impede the sound operation of the power markets. Some generators exercised the market power in California market by increasing the electricity prices and, in a point, caused the energy crisis in 2001. Research on market power is not newborn at home or abroad, but a certain and easy way to judge the existence of market power is yet unavailable. Traditionally, market concentration is used to make analysis on this issue. Rather than based on the generation side but from the load side, this paper presents an easy but feasible way to analyze the market power. Also, an analysis on the formulation of the market power in China deregulation and the application of market monitoring into preventing the exercise of market power is made.
