Integrated Control and Management Model of Regional Generation,Grid,Load,and Storage

针对当前面临的“新能源+规模化储能”调控策略缺失,主动支撑能力不足以及多系统林立等共性问题,本文以全国首个“源网荷储”一体化项目为例,探讨一体化调控管理模式的应用。主要研究内容包括区域风光功率联合预测,电网友好型新能源电站的“网-源”协调关键机制,风光储场站协同优化控制保护,新能源快速一次调频和虚拟惯量支撑等技术创新研发,以及风光储场站一体化数据集控平台研发和“集控+直控”双调度模式创新。研究结果表明,一体化集控平台从可测、可控、可调、可支撑四个方面为源网荷储一体化运行提供数据支持,满足新能源电站一体化接入及风光储稳定运行的要求,实现了全景智慧、电网友好、风光储协同的目标。研究成果有助于加快推动源网荷储一体化建设,并为规范化的源网荷储一体化实施路径提供参考。

In response to the current challenges including the lack of regulation strategy for"new energy+large-scale energy storage,"insufficient proactive support capacity,and the presence of multiple systems,this paper takes the example of the first integrated"generation-grid-load-storage"project in the country to explore the application of an integrated control and management model.The main research contents include joint forecasting of regional wind and solar power,key coordination mechanisms between grid-friendly new energy power plants and the grid,coordinated optimization control and protection of wind and solar energy storage stations,technical innovations in rapid primary frequency regulation and virtual inertia support of new energy,as well as the development of an integrated data control platform for wind and solar energy storage stations and the innovation of a"centralized control+direct control"dual dispatching mode.The research results show that the integrated control platform provides data support for the integrated operation of generation,grid,load,and storage from the aspects of measurability,controllability,adjustability,and supportability,meeting the requirements for the integrated connection of new energy power plants and the stable operation of wind and solar energy storage.It has achieved the goals of panoramic intelligence,grid-friendliness,and coordinated operation of wind and solar energy storage.The research findings help accelerate the development of integrated generation,grid,load,and storage projects,and provide reference for the standardized implementation path of integrated generation,grid,load,and storage.
