摘要
国家风光储输示范工程是大规模的集风力发电、光伏发电、储能及输电工程四位一体的可再生能源工程。工程规划建设百兆瓦级风电场、光伏电站及储能电站。文中重点阐述了示范工程风电、光伏发电和储能的规模及组成;介绍了示范工程的多组态运行模式及不同模式间的切换条件;同时,针对可再生能源并网问题,分析了平滑风光功率输出、削峰填谷、跟踪计划发电和参与系统调频,以及4种风光储系统联合运行控制策略,并结合实际运行结果进行验证。理论与实践证明风光储输联合发电模式具备可行性,符合新能源并网的要求,是新能源的发展方向之一,对新能源大规模并网具有一定的示范作用。
The national wind/photovoltaic/energy storage and transmission demonstration project is a large four-in-one renewable energy project,viz wind power,photovoltaic power,energy storage and transmission.The project is designed to build a hundred-megawatt-level wind farm,photovoltaic power station and energy storage station.Focusing on the scale and composition of wind power,photovoltaic and energy storage of the demonstration project,this paper describes the multi-configuration mode of operation and the switch conditions between different modes while analyzing the four control strategies of wind power,photovoltaic power and energy storage systems joint operation,namely,smoothing output power fluctuation,peak shaving and valley filling,tracking dispatch plan generation and power system frequency modulation,which are verified with actual operating results.It is proved by theory and practice that the combined power generation mode of wind,photovoltaic and energy storage is practical and capable of meeting the actual requirements on grid-connected renewable energy.This will be one of the leading directions for the development of new energy.And the wind/photovoltaic/energy storage and transmission demonstration project is a good demonstration of large-scale grid-connected new energy.
