电力系统中储能发展前景及应用关键问题研究

随着储能技术日趋成熟和成本快速下降，中国储能产业快速发展，逐步从研发示范向商业化阶段过渡，但整体来看储能产业还处于发展初期阶段，仍存在发展前景不明晰、技术标准不完善、商业模式和市场机制不清晰等问题。从发展规模、技术经济性、产业链等方面总结中国储能发展现状，基于“源-网-荷-储”协调规划理论，从宏观层面展望新能源大规模发展形势下中长期储能发展前景，研究储能在电力系统中的合理运行方式、与新能源消纳关系等重要问题；从微观层面对储能在电源侧、电网侧和用户侧等场景的应用关键问题及发展对策进行分析，并提出相关建议，为推动中国储能产业健康发展提供参考。

Research on Key Issues of Energy Storage Development and Application in Power Systems

With the maturity of energy storage technologies and rapid decline in cost, China's energy storage industry has developed rapidly, and the application of energy storage in power systems has gradually shifted from demonstration to commercialization phase. However, the energy storage industry is still in its early stage of development, and some problems still exist, such as the unclear development prospects, the unperfected standard systems, and the ill-defined business models and market mechanism. This paper reviews the status quo of China's energy storage development from the aspects of development scale, technological economy and industrial chain. Based on the coordinated planning theory of "generation-grid-load-storage", the prospect of medium and long term energy storage development are investigated from the macro layer, and relevant important issues are studied, such as the rational operation mode of energy storage and its relationship with new energy accommodation. And the key application issues of energy storage in generation side, grid side and user side are analyzed from the microscopic aspects, and related development strategies are studied. Relevant suggestions are put forward to provide support and reference for promoting the healthy development of China's energy storage industry.
