摘要

储能技术将在高比例风力发电、光伏发电等可再生能源发电的电力和供热系统里发挥重要作用

但现有针对电力系统转型的研究中

储能建模以抽水蓄能、锂电池、压缩空气储能等短期储能为主

对于氢、储热这类季节性储能技术关注不足。应用了电力行业长期规划与短期运行联合优化模型

以碳中和目标下中国电力和供热部门低碳转型路径为案例展开了研究。模型将抽水蓄能、锂电池、压缩空气储能、氢和储热作为储能技术选项进行建模

定量分析了碳排放约束下电力和供热部门的规划方案。结果表明

氢和季节性储热的应用将降低2060年煤电的装机容量、发电量和供热量

并对其季节性调节作用产生一定替代

同时将促进光伏的发展。未来氢呈现"春储夏用"秋储冬用"的特点

全年氢储量的峰值出现在5月

约为650万t;季节性储热呈现"春储冬用"的特点

储热量峰值出现在10月

约为3.2亿GJ。

Abstract

Energy storage technologies will play a crucial role in power and heating systems with a high proportion of renewable energy generation

such as wind and photovoltaic power generation. However

in existing research on power system transformation

energy storage modelling has mainly focused on short-term storage methods like pumped hydro storage

lithium-ion batteries

and compressed air energy storage

with insufficient attention given to seasonal energy storage technologies such as hydrogen and thermal storage. In this study

a joint optimization model for long-term planning and short-term operation in the power industry has been applied

and a case study has been conducted on the low-carbon transition pathway of power and heating sectors in China under the carbon neutrality goal. In this model

pumped hydro storage

lithium-ion batteries

compressed air energy storage

hydrogen

and thermal storage were modeled as energy storage technology options

and the planning schemes for the power and heating sectors under carbon emission constraints were quantitatively analyzed. Results indicate that the application of hydrogen and seasonal thermal storage will lead to a reduction in the installed capacity

power generation

and heat supply of coal-fired power plants in 2060

and will partially replace their seasonal regulation functions while promoting the development of photovoltaic. In the future

hydrogen will be characterized by "storage in spring for use in summer" and "storage in autumn for use in winter"

with the peak hydrogen storage occurring in May at approximately 6.5 million tonnes. Seasonal thermal storage will be characterized by "storage in spring for use in winter"

with the peak thermal storage occurring in October

totaling around 320 million GJ.
