电力市场环境下的发电容量充裕性--(二)几种现有方法的分析

State-of-the-art of Studies on Generation Capacity Adequacy in Electricity Market Environment Part Two Analysis of Several Existing Major Methods

鉴于单一能量市场模式难以确保发电容量充裕性,国际上已提出多种旨在解决该问题的方法。就设计思路、理论基础、实践经验和方法特点等方面,较系统地总结和分析了已提出的近似传统规划方法、容量费用模式、容量责任和装机容量模式、区域装机容量市场法、期权法、运行备用支付法和用户侧容量定购法等。对这些方法在理论上的优缺点和应用方面的可行性、适用范围、配套措施等阐明了观点,在此基础上对确保中国发电容量充裕性提出了初步建议。

Since it is well acknowledged that the energy-only market could not ensure the generation capacity adequacy, a lot of research work has been done around the world to explore new ways to solve this important and yet difficult problem. A comprehensive analysis and comparison is made to several widely employed or established methods including similar traditional planning, capacity payments, capacity obligations and installed capacity market, locatioflal installed capacity market, options, operating reserve payments, and capacity subscription, mainly from those aspects such as methodological design, theoretical foundation, practical experiences and basic features. Then, theoretical advantages and disadvantages, as well as the practical feasibility, the application scope and supporting measures of these methods are clarified. Finally, based on the above analysis and research, some preliminary suggestions are made for ensuring generation capacity adequacy in China.
