Abstract

The research of the energy storage technology has been an important driving force for the development of renewable energy, and it has become a consensus in the electricity market to introduce energy storage technology into the power system with renewable energy. At present, the power auxiliary service market (PASM) in China is still in the construction period. With the increasing investment scale of the energy storage market, energy storage is widely appeared in the PASM. In view of this situation, this paper takes various parts of Northwest China as an example, introduces the application of energy storage technology in the field of renewable energy, discusses the five main auxiliary service types of frequency modulation, peak regulation, reserve, reactive power regulation and black start, and gives the corresponding cost and benefit model. Finally, the business model of the energy storage participating in power auxiliary service is analyzed, and four feasible solutions are given considering the investment mode and operation mode of energy storage system.

高比例可再生能源储能的电力辅助服务与商业模式

储能技术的研究已成为推动可再生能源发展的重要动力，将储能技术引入可再生能源电力系统已成为电力市场的共识。目前，中国电力辅助服务市场仍处于建设阶段。随着储能市场投资规模的不断扩大，储能在PASM中广泛出现。针对这一情况，本文以西北各地区为例，介绍了储能技术在可再生能源领域的应用，讨论了调频、调峰、备用、无功调节和黑启动五种主要辅助服务类型，并给出了相应的成本效益模型。最后，分析了储能参与电力辅助服务的商业模式，并结合储能系统的投资模式和运行模式，给出了四种可行的解决方案。
