The paper presents the basic agc principle and agc generators operation situations in our country , and combines foreign agc ancillary service market pattern , and then brings forward agc ancillary service trade method , which adapts to our province grids 本文主旨在于综述agc的基本原理和我国agc运行状况，结合国外电力市场的agc辅助服务市场运营模式，提出适合我国省级电力市场的agc辅助服务的交易计划制定方法。
Through the study on the example , several achievements have been attained , they are as following : 1 . researching and developing the soft system of the optimally coordinated method in energy and ancillary services market and putting them into use , also concluding some significant results ; 2 . through the case , it can be concluded that the new bidding method of ancillary services is able to apparently reduce the total cost of ancillary services , and the management department can get the optimal plan through the bidding , while subjects to the market rules 研发了发电和辅助服务市场协调优化调度模型的软件系统，并把它们应用于实际，得出一些有意义的结论； 2通过实例得出这个辅助服务市场招标与交易的新方法能够明显减少辅助服务的总成本。采用这个新方法可以使市场运营管理机构通过招标得到最优的辅助服务方案，同时遵守给定的辅助服务市场规则。
Section iii proposes a possible organization of a reactive power market , a regional reactive power market established according to the distribution of the load and the reactive supply . the regional reactive power market is composed of a reactive energy market based on marginal pricing and a reactive capacity market based on a reactive regulating capacity payment . the cases in section iv , based on the market organization proposals and the reactive bid structure previously presented , performed on a five - bus system and the ieee 14 bus system , are used to analysis the effects of active bid , voltage control and power factor on the reactive marginal price 本文首先回顾了电力市场发展的历史和现状；然后对市场中的定价方法和无功辅助服务的内容及特点进行了总结，并介绍了一些国家的无功辅助服务市场模式和交易方法；接着立足我国国情，提出了单边开放电力市场下的无功市场框架：即根据负荷和无功源的分布特点建立区域无功市场，各区域无功市场又由相应的无功电量市场和无功容量市场组成；并提出了该无功市场模式下的机组报价模型和基于报价的以系统总购电费用最小为目标的无功电价计算方法；最后用一个5节点系统和ieee14节点系统进行了实例分析，初步研究了发电机有功报价、系统电压控制以及负荷功率因数对无功电价的影响，得出了一些有借鉴意义的结论。
This paper integrates the new ancillary services theories and the practice in our power industry reform and focuses on the following contents : 1 . the structure of the ancillary services markets which are independent on the energy market ; 2 . the optimally coordinated model of energy and ancillary services , and the method which com bines the sequential dispatch and the simultaneous dispatch ; 3 . a new study on how to bid in ancillary services markets ; 4 . the model of interruptable load in reserve market ; 5 . the method of distributing the fixed cost of the special transmission services 本论文把新型的辅助服务理论与我国的改革实践相结合，主要对以下几方面进行了研究： 1独立于主市场(电能市场)之外的辅助服务市场结构； 2发电市场与辅助服务市场协调优化调度的数学模型和一种由顺序调度法与同时调度法结合而成的最优协调调度方法； 3
The validity of the method is verified through sensitivity studies . this work emphasizes that the valuation of reactive power support services should be based on their contributions to system security and stability . from this view , we set up the model of capacity pricing and the structure of var capacity market 接下来，对国内外已营运电力市场的无功辅助服务市场情况进行分析，在总结各类市场的先进经验和欠缺之处的基础上，创造性地提出了统一计算和集中补偿的模式，建立无功容量市场和无功电量市场的设想，确定了本项研究的基本思路。
While the beginning of marketization of electrical power in china is later than other developed countries , there are many problems about power marketization needing resolved . especially in ancillary service market , they are far from other developed countries in scale , construction and operating process . based on competition principle , the method presented in this paper allows power network to make free choice of agc generation , which forms an improved competition model 我国的电力市场化起步较晚，所以电力市场化改革过程中存在很多亟待解决的问题，由于我国电厂的自动化水平较低，我国的辅助服务市场规模，结构和运作程序与发达国家都是有距离的，尤其是在辅助服务市场，在agc机组调度过程中，存在竞价上网的数学模型的建立问题。
