引言随着市场化改革的推进、数字经济的发展、气候变化的加剧、环境监管要求日趋严格以及国家“低碳经济”主题的最新调整,电力网络跟电力市场、用户之间的协调和交换越来越紧密,电能质量水平要求逐步提高,可再生能源等分布式发电资源数量不断增加,气候变化初露端倪,传统网络已经难以支撑如此多的发展要求,智能电网的概念应运而生。智能电网致力于建设具有信息化、数字化、自动化、互动化等智能技术特征的现代电力 Introduction With the advent of market-oriented reforms, the development of the digital economy, the aggravating of climate change, the increasingly stringent environmental regulatory requirements and the latest adjustment of the national “low-carbon economy” theme, the coordination between the power network and the electricity market and users and The exchange is getting closer and closer. The requirements of power quality level are gradually increasing. The distributed generation resources such as renewable energy resources are increasing. Climate change is at the beginning of the horizon. The traditional network can hardly support so many development requirements. The concept of smart grid has emerged. The smart grid is committed to building modern electricity with the characteristics of intelligent technologies such as informationization, digitization, automation and interaction
