【摘要】 我国目前正进行新的电力市场化改革,购售电双方将通过售电公司参与电力市场交易。新改初期售电公司交易模式的合理性将对购售双方的成本产生很大的影响。从售电公司角度出发,提出一种基于价差返回策略的集中竞价方法,通过引进返回系数,将竞价交易过程中购售方成交电量价差费按比例返回给双方,以减少双方交易成本。文中总结国外经验并结合我国目前新电改实际情况,建议售电公司采用在基于价差返回策略的集中竞价方法基础上,采取80%稳定电量采取中长期双边协商交易,20%电量实时电量采取价差返回策略集中竞价交易。更多还原

【Abstract】 At present,China is carrying out a new round of electricity reform by which buyers and sellers of electricity participate in electricity transactions through the power sales company. The rationality of the trading mode of the power sales company in the initial stage will have a great impact on the cost of both buyers and sellers. This paper proposes a centralized bidding method based on the price spread return strategy from the point of view of the sales company. By introducing the return coefficient,the price spreads of the traded electricity of the purchaser and seller in the bidding process are returned to both sides proportionally to reduce the transaction cost. Based on the experience in foreign countries and the actual situation of the new electricity reform in China,the paper suggests that the power sales company adopt the centralized bidding method based on the price spread return strategy,and 80% of stable electricity transactions be traded by medium-and long-term bilateral agreements while the balance(20%) of the real-time electricity be centrally traded through bidding based on the price spread return strategy.更多还原
