Identification of Typical Behaviors of Market Subjects in Competitive Power Market Environment

Abstract

In the power market, some illegal behaviors of market subjects violate the market rules. There also are some potential harmful behaviors, such as profiteering pricing, speculation, alliance, which do not violate market rules directly. These harmful market behaviors impair the competitiveness and effectiveness of the market, cause adverse effect for the optimal allocation of limited resources. Consequently, it will impair the efficiency of the electricity market. Market illegal behaviors can be judged, punished and controlled according to market rules; However, harmful market behaviors are difficult to be identified and controlled according to market rules, so an effective method must be established to identify, monitor and control them. According to the different characteristics of potentially hazardous behaviors, four methods are proposed in this paper, namely, index supervision method, quotation behavior supervision method, trading behavior analysis method based on expert system and market simulation test method to identify the illegal behaviors in the power market. Then, this paper takes the compliance analysis of market player behavior and the compliance analysis of electricity purchase price as an example to carry out simulation test.
