When programming the daily generation strategies, power plants consider not only the competitive bids in spot market and the original purchase contracts with distribution companies or users, but also the spinning reserve. Aiming at this goal, the paper puts forward a daily generating model, which is a nonlinear programming model containing integral and continous variables, to coordinate the power volumes of competitive bids, contract and the spinning reserve of power plants and thus to maximize their profits. Then, the model is simplified to ease its solving process, and solved by priority ranking method based on efficiency and quadratic programming. The simulation result of a case study shows that the proposed scheme is reasonable and practicable. 相似文献

为解决发电侧市场最高限价的设置问题,以美国的投资回报率法(ROR)、英国的零售价格指数法(RPI-X)和利润上限法为基础,提出了动态价格上限设置模型.讨论了动态价格上限模型的利润因子取值及对新老电厂的激励作用,证明该模型能使投资回报具有公平性.此模型既能有效抑制边际成本定价造成的价格尖峰问题,又能激励效率,吸引投资. 相似文献
