为满足可再生能源大规模接入的需求，亟需提高能源系统大时空范围的优化配置能力。储能是实现该目标的有效手段，但传统研究一般集中在电力系统的范畴内。该文跳出电力系统范畴，在电-热联合系统的层面总结能源生产和消费的匹配问题。包含大容量储热的电-热联合系统可以充分利用电力系统和热力系统物理特性的优势，提高能源系统大时空范围优化配置能力。联合系统中含有电、热2种能量形式，特性差异很大。现阶段研究的重点是电力系统与热力系统的差异性与互补性，包含大容量储热的电-热联合系统的动静态数学模型，不同应用场景下储热装置的优化设计方法，以及包含电、热2种能量形式的协调优化控制策略和综合能量管理方法。

To meet the demand of large-scale renewable energy integration, the allocation capability of the energy system in large time and space scope should be improved. Energy storage is an effective way to achieve this goal, and it is generally studied within power systems. Out of the power systems scope, this paper analyzed the match of energy production and consumption in the combined electricity and heat system containing large capacity thermal energy storage. The combined system containing two forms of energy with different characteristics can make use of the advantages of both the electrical system and the thermal system so as to promote the allocation capability of the energy system in large time and space scope. The following research priorities were suggested:the diversity and complementarity between the two systems, the static and dynamic models of the combined system, the optimal design of thermal storage devices in various application accessions, and the optimal control strategy and energy management method of electrical and thermal energies.
