摘要
在电力市场环境下，传统的发电计划转变为购电计划，其内涵发生了质的变化，购电计划的公平性和最优性是建立电力市场的前提。文中结合我国的实际情况，建立了以电网为核心的买电型短期交易计划的模型，提出了兼顾电网交易中心与发电商之间利益合理分配的浮动边际电价的新概念，并从电厂的角度给出了短期交易计划的公平性准则，从电网交易中心的角度给出了最优性判定准则。算例表明，根据该模型及其算法制订出的开停机计划和功率分配，能够体现电力市场的公平、公正、公开原则。
Electricity m arket has great im pact on pow er system dispatching operation. The justice and optim ality of tradeplanning are prerequisite. This paper presents a novel m odel of short term trade planning in a com petitive electricity pool⒙w ith the settlem ent rules involved in the objective function. Moreover⒙the conceptofsystem m arginalprice is im proved so asto reflect the reasonable distribution ofbenefits betw een transaction centers and suppliers. And the justice criterion from thestandpoint of pow er plants is proposed⒙as w ell as the optim ality criterion from the standpoint of transaction centers. Thedescribed m ethod has been tested in a real pow er system ⒙and the results dem onstrate that generation scheduling and pow erdistribution based on the proposed m odelcan reflect justice⒙im partiality and transparency of electricity m arket.
