长时储能技术及典型案例分析
Analysis of long-term energy storage technologies and typical case studies
摘要
Abstract
With the transformation of the power system to low-carbon,the proportion of new energy installed capacity is increasing year by year,renewable energy power generation has the characteristics of intermittent,the main power generation period and peak power consumption period are misaligned,there is an imbalance between supply and demand,and the demand for flexibility in power balance is intensified,and long-term energy storage power stations have become a magic weapon to solve the problem.According to the development of long-term energy storage technology,the technical characteristics,advantages and current bottlenecks of pumped storage,compressed air,lithium-ion batteries,flow batteries,molten salt heat storage,and hydrogen energy are analyzed,and the typical application projects of the above energy storage technologies are analyzed.Then,the typical scenario applications of energy storage are analyzed from different sides of the power supply side,the power grid side and the user side,and the application comparison of seven energy storage technologies in multiple scenarios such as energy transfer,auxiliary services,black start,and smooth new energy output is expounded.The technical parameters,battery selection,system wiring,energy management and other issues of chemical energy storage demonstration project,heat storage demonstration project and mechanical energy storage demonstration project were summarized and analyzed,and finally the future energy storage power station technology was prospected.关键词
