【摘要】 电力工业已在发电领域引入了竞争,发电与输电由过去的垂直一体化调度转变为商业形式的买卖交换。电网公司在与电力企业的博弈中既要让发电企业降低成本增加消费者剩余,又要激励电力投资保证供给义务,则合同电量的时间长短与合同电价的制定是同样重要的。其时间的长短首先应确保集资电力企业能回收其投资成本,又要管制在位企业抢先扩张生产能力,以长期合同阻止新进入者,形成市场力;然后对电网公司和电力企业在区域市场撮合交易过程中的博弈行为进行了建模和分析;采用迭代法对安顺新建和扩建电厂以及天生桥新建电站的投资回收给出了合同时间的求解过程,采用遗传算法对交易中竞争电量的博弈模型进行了计算和验证。更多还原

【Abstract】 Competition has been introduced into electricity power area by electricity industry,style of generating and trans-mitting electricity converts from vertical unity distribution to commercial exchange.In the game with power_generating cor-poration,power grid corporation should not only make its rivals to reduce generating cost to increase consumer surplus but also encourage them to raise electricity investment so that supply duty is insured,thus,setting up appropriate time of contract electricity is as important as establishment of electricity price.During which time,electricity power corporation should be able to recover its investment,also,the time should not be so long that present corporation can form market power by ex-panding manufacturing ability with the long-time tract;we set up a model of game of the regional market business transac-tions between power grid corporation and electricity power corporation and make an analysis;method of iteration is used to calculate appropriate contract time for investment recovering of Anshun and Tianshengqiao power stations.The Anshun sta-tion is building a new station and expanding its old one,while the later is building a new station.We have uses algorithms to calculate and examine the model of game.更多还原
