面向新能源消纳的关键储能技术研究综述

Review of key energy storage technologies for new energy consumption

随着双碳战略目标的持续推进,风、光等可再生能源被大规模开发利用,然而可再生能源的波动性、随机性不可避免地制约着新型电力系统稳定发展。现阶段新能源消纳问题突出,首先详细介绍了新能源消纳面临的挑战:空间错配、时间错配、灵活调节能力不足及电网安全问题,而储能技术是解决新能源消纳难题的必要策略,新型电力系统下源网荷储一体化发展是大势所趋。对现阶段的关键储能技术(物理、电化学、电磁及相变储能)进行了全面汇总和对比,分别从发电侧、电网侧及用户侧入手,对储能技术的典型应用场景进行了分析。最后,对新型电力系统下储能面临的经济性和安全性挑战及未来的发展方向进行了扩展。

Renewable energy such as wind and solar power energy are being developed and utilized on a large scale with the continuous promotion of the"dual carbon"strategy goals.But the volatility and randomness of renewable energy inevitably restrict the stable development of the new power system.At present,the problem of new energy consumption is prominent,so we first introduced the challenges faced by new energy consumption in detail:space mismatch,time mismatch,insufficient flexible adjustment capacity and power grid security issues.Energy storage technology is a necessary strategy to solve the problem of new energy consumption.The integrated development of source-grid-load-storage under the new power system is the general trend.In this paper,the key energy storage technologies at this stage:physical,electrochemical,electromagnetic and phase change energy storage technologies were comprehensively summarized and compared.Subsequently,the typical application scenarios of energy storage technology were analyzed from the power generation side,the grid side and the user side.Finally,the challenges of economy and security faced by energy storage under the new power system and the future development direction were extended.
