面向电力现货市场的独立储能经济性分析与容量补偿机制探索

A Study on Tech-economic Analysis on Independent Energy Storage in Spot Power Market and Associated Capacity Mechanisms

  • 摘要: 新型储能技术的快速进步为提升电力系统灵活性提供了更多技术选择,也为构建竞争性灵活资源市场提供了条件。国外部分独立系统运营商为适应储能物理特性,在能量市场、辅助服务市场、容量市场、输电资产方面做了机制探索;国内一系列电力体制改革文件强调探索容量补偿机制以鼓励新型储能投资建设,但国家层面尚未出台针对新型储能的容量补偿政策。结合主流新型储能技术经济参数与国内典型地区现货市场价格曲线,测算了现货市场环境下各类新型储能经济性差异与未来趋势,并基于国内外容量补偿机制经验与研究成果,研究不同容量补偿机制情景下容量电价对提升新型储能经济性的作用。研究发现,以锂电池为代表的新型储能已开始显现相对于抽水蓄能的经济性,赋予新型储能独立市场地位,鼓励其参与电力现货市场,有助于降低新能源发电系统消纳成本。然而,目前新型储能参与电力现货市场仍面临阻碍,为此在容量补偿、现货与辅助服务市场建设等方面给出了政策建议。

     

    Abstract: The rapid progress of new energy storage technologies provides more options for improving the flexibility of the power system and the opportunities for building a competitive and flexible power market. To adapt to the physical characteristics of energy storage, some foreign independent system operators have explored the market participation mechanisms for new energy storage. In China, a series of domestic power system reform documents have emphasized the importance of capacity remuneration mechanisms to encourage new energy storage investment, but the national-level policy is still under discussion. Combining the technical and economic parameters of mainstream new energy storage technologies with the spot market price curves of typical areas in China, the differences in the economics of various types of new energy storage under the spot market environment and the future trend are measured, and based on the experience and research results of capacity compensation mechanisms at home and abroad, the role of capacity tariffs in enhancing the economics of new energy storage under different capacity compensation mechanism scenarios is investigated. The results show that the new energy storage represented by lithium-ion batteries have begun to present competence in the spot market compared with pumped hydro storage. Giving new energy storage an independent market position and encouraging them to participate in spot markets helps reduce the system integration costs of variable renewable energy. However, the current participation of new energy storage in the power spot market still faces obstacles, so this paper gives policy suggestions for new energy storage in terms of capacity compensation, ancillary service, and spot market development.
