發電業自由化電源調度之研究

Abstract

發電業自由化電源調度之研究 摘 要 發電業自由化是政府政策。近年來，政府為解決電源 供應不足問題，開放發電業自由化，鼓勵民間興建電廠，使得電力來源多 元化。 獨立發電業於民國87年開始運轉供電，對台電的營運將造成影 響。如何才能使電源採購達到公平、有效率，及如何在兼具系統安全與經 濟的原則下，調度所購得的電力，是兩個值得研究的問題。 本研究的 目的是建立一個電源採購模式與電源調度模式。為了達成上述目的，本研 究首先分析、比較國內外電源採購與定價方法。其次以發電成本結構特性 （包括能量與容量成本 )、台灣地區電力系統、負載特性，配合利用區域 平衡、電源互聯、保證發電時段保發電量等觀念和電源採購影響因素，如 數量、價格、時間和地點等□建立一個符合國內需要的電源採購與電源調 度模式，以促使競爭環境的形成及達到經濟調度的目的。 論文最後， 藉由本研究之主要發現，提供一些建議和策略，俾供發電業自由化後，台 電電源調度部門有關電源採購與電源調度決策之參考。 A Study of Power Dispatch under the Deregulation of Power Generation ABSTRACT The deregulation of power generation is government policy to solve the severe power shortage in recent years. Encouraging the Independent Power Producer(IPP) enters the electricity market to upgrade energy utilizationefficiency and to build up a fair power purchasing market. The IPP's joining system in 1998 will influence Taipower's operation. Howto purchase power fairly and efficiently and to operate the system economicallyand safely after IPP's units being connectted to Taipower's system are two im-portant issues deserving to study. The purpose of this study is to build up a power purchasing model and power dispatching model. To achieve this, this paper first analyzed and comparedthe methods of the power purchasing, pricing after the deregulation of power generation between Taiwan and foreign situation; Secondly, this study is based on the characteristics of the production cost structure (includingenergy and capacity cost) of power generation, Taipower's system and load.Making use of the concept of local balance, power interconnection, the powerproduction of guaranteed hours and the factors of power purchasing, such as:quantity, price, time and location, to set up a power purchasing model and power dispatching model to achieve power purchase fairly and the economic dispatching of power generation. Finally, according to the significant finds of this study, some suggestion and strategic operation are referred in making decision in power purching anddispatching of deregulation of power generation.
