摘要
比较了以美国加州和英格兰—威尔士为代表的两大类运行备用辅助服务市场 ,认为英格兰—威尔士模式对我国初期的电力市场更有参考价值。建议我国运行备用辅助服务市场采用在一日前现货交易发电主市场定价基础上同时定价 ,即事先定价 ,而在当日强调各机组服从调度 ,事后按既定价格结算。实现概率学意义下的公平合理性。在简易当量电价法基础上发展了计入运行备用辅助服务的随机性简易当量电价法。采用了随机生产模拟技术 ,引入了期望边际机组和期望边际电价的新概念 ,并区分被调度加载和不被调度加载两种情况。
Two kinds of ancillary service (AS) market modes for operating reserve. California's and UK's. are compared. Itis concluded that the UK's mode is more referential for the power market in China. Then suggest that for Chinese AS marketof operating reserve a centralized reserve dispatch mode and an integrated probabilistic pre--pricing method could be employed.Because the simple and easy electricity value equivalent (EVE) pricing method is suitable to Chinese power market. aprobabilistic simple and easy EVE method for day--ahead pricing with AS market using the stochastic production simulation isdeveloped. It is fair in the probabilistic sense. Some new concepts. e. g. the expected marginal unit and expected marginalprice are evolved. The units to be loaded and unloaded for pricing are distinguished. Finally a case study is given.This project is supported as a key one by National Natural Science Foundation of China (No. 59937150).
