市场力的评估和监管是保证电力市场有效运行的重要内容之一。文中提出了按照产业经济学中的结构一行为一绩效(SCP)分析框架建立面向整个市场和发电商的市场力评估指标体系,然后用模糊层次综合评估方法对市场、各阻塞区域、各发电商的市场力警戒级别进行实时评估和监控,根据得到的5级警戒级别对市场监控图着以不同警戒色,并按照对S,C,P的警戒级别评估结果做出相应的监管决策机制,可以有效提高监管效率。最后以实际电力市场的市场数据为算例,验证了文中提出的基于SCP和模糊层次综合评估的市场力警戒和监管决策机制可以有效识别出市场中S,C,P各环节的市场力水平以及各发电商的策略报价行为。
Market power assessment and regulation is to ensure the effective operation of the power market one of the important elements. In this paper, we set up an index system of market power evaluation for the whole market and power producers according to the structure-behavior-performance (SCP) analysis framework in industrial economics. Then we use the fuzzy comprehensive evaluation method to evaluate the market, blocked areas, Of the market power alert level real-time assessment and monitoring, according to the five levels of warning on the market monitoring chart with different warning color, and in accordance with the S, C, P warning level assessment results to make the appropriate regulatory decision-making mechanism can be effective Improve regulatory efficiency. Finally, taking the market data of the real electricity market as an example, it verifies that the market vigilance and regulatory decision-making mechanism based on SCP and fuzzy hierarchy comprehensive assessment proposed in this paper can effectively identify the market forces of S, C and P in the market and Strategy of each power generator quotes.
