摘　　要：双边合同是电力市场的主要交易形式之一,其同样也可以应用于发电权交易。在当前广泛研究的发电权集中撮合交易市场的基础上,增加合同交易,即建立混合发电权交易市场,更有利于发电权交易市场的形成和健康运营,但同时也给阻塞调度带来了一些新的问题。当系统发生阻塞因而需要削减负荷时,如何公平对待2类不同的发电权交易,即如何适当地确定各类交易的削减量,是一个值得研究的问题。为此,发展了适用于有混合发电权交易市场的电力系统阻塞协调调度模型,提出了通过公平性约束实现对不同类型的发电权交易的公平调度。最后,以IEEE单区域RTS96系统为例,说明了所提出的模型和方法的基本特征。Bilateral contract is one of the major trading schemes in electricity markets,and certainly could also be employed in generation-rights trading. Up to now,the centrally matchmaking trading mode has dominated the generation-rights trading in practice,but bilateral contract is surely another feasible mechanism for consideration. Based on the successful experience in electricity market practices,it is believed that the combination of the centrally matchmaking trading mode and bilateral contract mode,i.e. creating a hybrid market,could lead to a better market operation for generation-rights trading. However,the employment of a hybrid market for generation-rights trading could result in some new problems for system dispatch. In case of congestion,how to curtail equally and reasonably between these two kinds of trading is especially an important issue to be investigated. Given this background,efforts have been made to develop coordinated congestion dispatching models in a hybrid generation-rights trading market. With the enforcement of a coordinated constraint,the two kinds of trading could be treated in a non-discriminatory way. The feature of the developed models is demonstrated with case studies of the IEEE one-area RTS 96-bus system.
