电力零售市场全流程市场力监测方法

Whole-Process Market Power Monitoring Method in Electricity Retail Market

市场力监测是电力市场监管中重要的一环,是实现市场良性运行的必备手段。随着电力市场的逐步开放,电力零售市场规模不断扩大,但相应的零售市场监测机制尚未得到完善。因此,分析了零售市场滥用市场力的行为,设计了市场力监测指标体系,明确了市场力监测指标的衡量标准,提出了零售市场交易的事前、事中、事后3个阶段全过程的市场力监测方法,并利用灰色综合评价方法对售电公司的市场行为加以评价。最后,通过构建事前防范、事中监测及事后分析的算例验证了该方法对于电力零售市场全流程监测的有效性,为今后建立电力零售市场监管体系提供了一定参考意义。
