Transmission investment and expansion planning in electricity market environment

Abstract

One of the most serious challenges for power industry restructuring is to maintain power system reliability at an acceptable level and to promote the overall economic efficiency of the whole power industry. To this end, transmission investment and expansion is inevitable. In the past decade, much effort has been made to address institutional structures, business models, incentives and regulation to assure appropriate transmission investments be made, and to develop workable assessment and planning methods for the deregulated environment. In this paper, a comprehensive survey is made on the state-of-the-art of several important issues associated with transmission investment and expansion planning in the electricity market environment, including: challenges of transmission investment and planning in the competitive market environment; transmission investment; merchant transmission; transmission rights; business models; transmission regulation; management of transmission investment and expansion; transmission planning methods; international experience.

電力工業改革面對的一個最重要的挑戰是維持電力系統運行的可靠性在可接受的水平的同時提高整個電力工業運營的經濟效率。為此,輸電投資與輸電擴展不可避免。為了確保電力市場環境下適量的輸電投資和發展適用于輸電系統運行評估與擴展規劃方法,國內外學者就與此密切相關的工業組織結構、商業模型、激勵和管制等方面的問題做了很多研究工作。文中對與電力市場環境下輸電投資和擴展規劃相關的一些重要問題進行了較為全面而系統的綜述。這些問題包括：在競爭的市場環境下輸電投資和擴展規劃所面臨的新的挑戰；輸電投資問題；商業輸電；輸電權；商業模型；輸電監管；輸電投資和擴展規劃的管理；輸電規劃方法；國際經驗。
