摘要
在电力市场环境下，仍然需要对输电系统进行监管，因为其仍具有自然垄断特征，且要为实现公平竞争提供必要的场所。输电监管的一个主要目标就是要促使输电系统在满足给定的可靠性要求的同时使经济成本最低或经济效益最高，例如使系统以最小的总成本向用户供电。具体来讲，对基于管制的输电投资与扩展规划进行监管的主要目的是降低未来不能有效利用输电设备的风险，而对基于市场驱动的输电投资与扩展规划进行监管的主要目的是遏制有损整体社会福利的输电投资。
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.
