面向低碳经济运行的新型电力系统态势感知技术综述

Review on situational awareness technology in a low-carbon oriented new power system

构建以新能源为主体的新型电力系统,既是我国电力系统转型升级的重要方向,也是实现碳达峰、碳中和目标的关键途径。如何充分应用态势感知技术适应多样化、差异化的不同场景,成为保障新型电力系统可靠、安全、优质、低碳和经济运行的关键突破点。立足于新型电力系统的典型特征,首先,从电源侧、电网侧、负荷侧、储能侧4个方面对新型电力系统的关键特征和主要问题进行了分析;然后,从低碳经济运行的视角,深入浅出阐述了新型电力系统态势感知技术在态势觉察、态势理解和态势预测3个阶段中各自主要的关键技术;最后,从低碳经济运行的特点出发,阐述了面向新型电力系统的态势感知关键技术和未来发展趋势,以期为后续新型电力系统的建设、运行等提供一定的借鉴。

Constructing a new energy oriented power system is not only an important direction for the power system transformation and upgrading in China,but also a key means to achieve the goals of carbon peaking and carbon neutrality.The way of adapting situational awareness technology to diverse and differentiated scenarios has become the breakthrough point of the reliable,safe,high-quality,low-carbon and economic operation of the new power system.Typical features and main problems of the new power system are analysis from four aspects,source,network,load and energy storage.Then,to achieve the low-carbon and economic operation of the new power grid,key points in three application phases of situational awareness technology in the power grid which are situational perception,situational understanding and situational forecast are expounded.In the end,application and prospects of the situational awareness technology in the low-carbon oriented new power system are elaborated by taking the characteristics of low-carbon and economic operation of the new power system into consideration,which provides reference for the construction and operation of subsequent new power systems.
