摘　　要： 持续时间不同的电力段,其生产成本以及对电力系统的贡献均不同,为此,文中将电力分段交易方式引入到双边合同中,包括电力远期合同和电力期货合同。电力按照其持续时间的长短分为连续的几段,各段以不同的价格分别交易,发电商及用户可根据不同情况选择适当的电力段进行交易。通过对双边合同中分段交易的分析结果表明,电力分段交易符合电力系统的生产和消费特性,与分时交易相比用户能够得到更廉价的电力。以分段灵活电力合同为例,对选择不同电力段的分段灵活电力合同以及分时交易的灵活电力合同的比较分析表明,分段灵活电力合同体现了市场同质同价原则,并且有效地提高了电力双边合同市场的效率。对于其他采用分段交易的电力合同也将得到同样的结论。 Electricity is divided into several blocks according to its continuation time, and each block traded in its unique price, this is called block trading. And the traditional trading method is called hourly trading which trade electricity hour by hour. The electricity blocks with different continuation time have distinct cost and contribution to the safety of power systems. So the block trading method is introduced into bilateral contracts including forward contracts and futures. Generators and customers can select the electricity blocks to trade according to their requirement. The analysis of block trading in bilateral contracts shows that it is suitable for the generation and consuming of electricity in power systems and block trading can supply customers with cheaper electricity compared with hourly trading method. The block flexible electricity contract is selected to contrast block trading and traditional hourly trading quantitatively. The comparison indicates that the selection of block can significantly influence the contract price and block trading can improve the efficiency of bilateral market.
