摘要
随着电力系统向低碳化转型,新能源装机容量占比逐年增长。可再生能源发电具有间歇性的特点,主要发电时段和高峰用电时段错位,存在供需不平衡,电力电量平衡对灵活性的要求加剧。长时储能电站成为破解问题的有效有段。针对长时储能技术发展概况,首先分析抽水蓄能、压缩空气、锂离子电池、液流电池、熔盐储热、氢储能的技术特性、优势及目前瓶颈,统计以上储能技术的典型应用工程;然后从电源侧、电网侧和用户侧分析了储能的典型场景应用,阐述了多种储能技术在能量转移、辅助服务、黑启动、平滑新能源出力等多场景下的应用对比;总结分析了化学储能示范工程、储热示范工程、机械储能示范工程的技术参数、系统接线、能量管理等问题;最后对未来储能电站技术进行了展望。
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.
