摘要
电力市场化进程是电力工业发展的必然趋势,市场化会带来许多与过去的垄断经营模式不同的新问题。文章讨论在电力市场环境卜电网安全保证体系问题,主要包括电力系统统一规划和充裕度问题、辅助服务和运行备用问题以及系统调度和输电系统备用问题共三个部分。建立电网安全保证体系不是单纯的技术问题,特别是在市场经济条件下,解决电网安全问题时,不仅要考虑在安全性和经济性之间寻求适当的折衷,而且还要协调各市场主体之间的利益,涉及到体制和法律法规等方面的问题。作者就这些问题进行了分析,并指出了今后研究工作将面临的挑战。
Electricity markets are being restructured to become more competitive and efficient. Traditionally, power systems were tightly controlled by vertically integrated utilities. Now a system operator must depend on voluntary participation by numerous suppliers for energy and reserves. The author discusses the problems encountered in power system security and reliability including centralized planning and adequacy of power systems, ancillary services and operation reserve, system operating and transmission capacity reserve problems. Establishing electric network security setup is not a merely technique problem. To solve the problem it not only needs to seek compromise between security and economy, but also to coordinate benefits among market participants. These issues are analyzed and the challenges that may be faced in future study on power network security in the market environment are presented.
