目前国内外运行的电力市场中大多设置了允许的发电公司报价上限 ,以限制发电公司滥用市场势力和降低输电公司的财政风险。对于零售电价固定的单一购买者模式的电力市场 ,设置报价上限尤为必要。文中从监管机构的立场出发 ,基于事后分析法 ,对设置发电公司报价上限的问题做了初步探讨 ,提出一种启发式方法 ;以电力市场过去一段时间 (如 1年 )内每个交易时段的实际电价和电量数据为基础 ,识别出市场清算电价 (MCP)的概率分布函数 ,并将MCP的期望值表示为报价上限的函数 ;然后 ,根据电网公司的平均成本和售电价格 ,即可推算出合理的报价上限
At present, most of the power markets operated both at home and abroad have set maximum quotations of power generation companies allowed to limit power company abuse of market power and reduce the financial risks of transmission companies. For a single buyer-mode electricity market with a fixed retail price, setting quotes caps is especially important. Based on the post-incident analysis method, this paper makes a preliminary study on setting the upper limit of quotation for power generation companies from the perspective of regulators and puts forward a heuristic method. Taking the electricity market in each trading period in the past period (for example, 1 year) Based on the actual electricity price and electricity consumption data, the probability distribution function of the market clearing price (MCP) is identified, and the expected value of the MCP is expressed as a function of the quotation price upper limit. Then, based on the average cost of the grid company and the selling price, Reasonable quote ceiling
