【摘要】 大用户直购电模式是电力市场改革中引入的一种新型购电模式，它不但能进一步挖掘电力市场潜力，更重要的是在售电侧引入竞争机制，完善电价形成机制，以价格信号合理配置电力资源。 本文借鉴了国外直购电开展的经验，结合中国电力市场化改革方向，论述了大用户直购电模式中的重点和难点问题，包括直购电模式与电网安全性问题，大用户电价现状及问题，直购电中的输电阻塞管理及阻塞分摊，直购电输电过网费计算，直购电与建设自备电厂的经济性比较，直购电监管问题、信用问题和结算问题。本文对大用户直购电上述问题的研究及结论，为大用户直购电模式在我国的广泛应用提供了有益参考。更多还原

【Abstract】 The direct power-purchase pattern for large user is a new purchase pattern during the reform of electric marketization in China. Not only can it mine the potential power market, but it could introduce the competition mechanism on the side of sale, perfect the mechanism of electric pricing and reasonably assemble the power resources on the base of price.Reference to the experiments of international direct power-purchase patterns and the revolution direction of Chinese electric market, the paper studies some important and hard problems in the pattern of direct power-purchase for large user, which include the relationship of the direct power-purchase pattern and power-grid safety, the problems of large user’s recently list price, the congestion management and congestion cost distribution, the wheeling cost of direct power-purchase, the economic comparison between the direct power-purchase pattern and the construction of the self-supply power plant for large user, the management of supervision, credit and balancing the account. The research and its conclusions in this paper on direct power-purchase for large user will provide a beneficial reference to developing and extensive application of the direct power-purchase pattern for large user in China.Xiang Zhen(Management Science and Engineering) Directed by prof.
