碩士 === 國立中正大學 === 電機工程所 === 97 === The improvement of operating efficiency and reduction of production cost are the main goals of the electric market reform. Since early eighties, Taiwan’s government provided many economic incentives to attract local or foreign investors to establish independent power producers (IPPs) for alleviation of the rapidly demanded electric power in our country. The purpose of setup of IPPs is to promote the competition of the generation market. Therefore, through the proper reform of the structure of electricity business as well as the improvement of production and utilization efficiency, the sufficient power supply with low cost for economy growth can be achieved. Because generation business is the most competitive business entity, it requires estimating the economic benefits of the generation and a strategic analysis for bidding to survive and succeed in the future competitive environment. Also, a great number of the combined cycle units are installed, the versatile operation mode of such units makes the unit commitment quite complicated. In addition, there are some economical issues related to pumped-storage hydro unit generation. All these factors lead to the difficulties to obtain a better economic evaluation of the electric utilities’ generation cost and a strategic analysis for bidding in future power markets. Therefore, the purpose of this thesis is developing an efficient information system to provide a tool for estimating the economic benefits of the generation and a strategic analysis for bidding. This information system takes into account constraints of unit commitment (include combined cycle units), power purchase/sell contracts, electric energy transmission limits of power network, pumped-storage hydro unit generation limits, unit maintenance constraints, and the impact of changes of demand-side management. The developed information platform is to be utilized for automatically integrate and analyze the accessed data in practice. Also, the information system can be used as a profit-making tool for market participants in a deregulated environment.
