电力市场环境下的输电投资与扩展规划

电力工业改革面对的一个最重要的挑战是维持电力系统运行的可靠性在可接受的水平的同时提高整个电力工业运营的经济效率。为此，输电投资与输电扩展不可避免。为了确保电力市场环境下适量的输电投资和发展适用于输电系统运行评估与扩展规划方法，国内外学者就与此密切相关的工业组织结构、商业模型、激励和管制等方面的问题做了很多研究工作。文中对与电力市场环境下输电投资和扩展规划相关的一些重要问题进行了较为全面而系统的综述。这些问题包括：在竞争的市场环境下输电投资和扩展规划所面临的新的挑战；输电投资问题；商业输电；输电权；商业模型；输电监管；输电投资和扩展规划的管理；输电规划方法；国际经验。

Transmission Investment and Expansion Planning in Electricity Market Environment

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.
