百兆瓦级锂电池储能电站的工程造价及效益研究

Research on Engineering Cost and Benefit of 100 MW Lithium Battery Storage Station

储能是推进智能电网建设,加强城乡电网建设和增强电网优化配置的重要依托技术,同时也是智能电网的关键支撑技术。该技术在电力系统中的应用主要包括削峰填谷,提高系统运行稳定性和供电质量,并减少系统备用需求的作用。为探讨百兆瓦级大容量电池储能系统经济效益,为电池储能系统更高层次、更大规模的推广应用做准备,本研究采用两种市场上的主流锂电池指标,研究百兆瓦级锂电池储能电站不同布置方案的工程造价及在多种运行模式下的效益。

Energy storage is an important supporting technology for promoting the construction of smart grids,strengthening the construction of urban and rural power grids and enhancing the optimal allocation of power grids.It is also a key supporting technology for smart grids.The application of this technology in power systems mainly includes stabling electrical load,improving system stability,and reducing the need for system backup.In order to explore the economic benefits of the 100 MW battery storage station and prepare for more application of the battery energy storage system,this study uses two main lithium battery indicators in the market to study the engineering cost of different layout and the benefits in different modes.
