Along with the development of the reforming of state power system , straight power supply to big consumer is the demands of reformation and marketable requires , so it will become an important means of electric power marketing 随着国家电力体制改革的推进，它将成为电力营销的重要手段，大用户直供电既是改革的需要，也是市场的需要。
( 3 ) in the present electricity power reform , we should consider contractual pricing as the first choice , and independent power plants should be encouraged to supply electricity power to big electricity power users ( 3 )在当前的电力市场化改革中，应优先考虑协议定价，重点推广对大用户直供电；同时，逐步创造条件，慎重实施部分电量的竞价上网。
( 2 ) discuss participators " market powers and bargaining modes , and bring forward the measures which reduce or restrict participators " market powers , the choices of bargaining modes , and the ways of signing the contracts in electric power market 探讨电力市场下电力大用户直接购电(发电商直供)中的主体的市场势力和交易模式，提出交易中降低或限制参与者市场势力的措施、交易模式的选择、以及签订合同的方式。
( 4 ) study one consumer ' s bargaining with one generator . make use of the correlative knowledge of double - direction auction and sequential negotiation in game theory to study bilateral quotation game . bring forward the instance to analyze the feasibility 研究单一电力大用户与单一发电商的交易，利用非完全信息静态博弈理论中的双向拍卖和序贯谈判相关知识来研究双方交易报价博弈，并通过算例分析交易的可行性。
Aiming at the characteristics of the power utilization system in daqing , this paper designs the main project of the power utilization monitoring system , and highlight the character of real - time in monitoring , and put emphases on monitoring of operation in grid and power utilization of large users 针对大庆电力系统特点,设计了用电监测系统主体方案,突出了监测的实时性,重点对电网运行和大用户的用电情况进行监测。
In pdsn system , data packet between ms and pdsn compressed by compressing algorithm can reduce the size of the transmitting packet , improve the efficiency of data transmission and support large number of simultaneous connected users 在pdsn ( packetdataservicenode :分组数据服务节点)系统中,用压缩算法对移动用户与pdsn之间传输的数据报文内容进行压缩,可大大减小传输报文的大小,提高数据传输速率,支持更大用户的同时接入。
However , the platforms at present are all isolated , and the different systems can neither cooperate nor distributing widely , neither carry simulation alternatively through internet nor accommodate the large scale of alternatively simulation service which provided by the internet 而现有的仿真平台都是孤立的，不同的系统之间不能够协同工作，不能进行广域分布，不能通过internet进行交互仿真，不能适应在internet提供大用户量交互仿真服务。
With the stepwise development and improvement of china electric power market , it will be inevitable trends which large electric power consumers will buy electric power directly from the generators ( or generators will supply directly to large consumers ) in the future 随着我国电力市场的逐步发展和完善，电力大用户直接购电(发电商直供)将成为必然趋势，开展电力市场下的电力大用户直接购电问题的研究对电力市场的发展和完善也将起着重要作用。
