新型电力系统下的电网安全挑战与对策研究

Challenges and Countermeasures of Grid Security Towards a New Type of Power System

新型电力系统的发展给电网安全带来了一系列挑战,包括自然灾难、设备故障、电网管理、恶意破坏等传统风险,以及大规模可再生能源接入和信息技术快速发展等新兴安全问题。文章梳理了国外电力系统及我国新型电力系统的发展特征和形势,研判了新型电力系统下的电网安全风险和挑战,并从预测预警预判技术、极端气候对电网的影响、网络信息安全、风险管理标准4个方面梳理了全球应对电网安全的措施。在此基础上,提出加强电网前瞻性规划部署、提升电网资源配置效率和整体韧性、推动先进技术研发和应用、完善风险管理措施等应对建议,期望为我国电网提高电力供给能力、安全稳定性、韧性提供参考依据。

The development of a new type of power system brings a series of challenges to grid security,including traditional risks such as natural disasters,equipment failures,grid management and malicious damage,as well as emerging security issues such as large-scale renewable energy access and rapid development of information technology.This paper compares the development characteristics and situation of foreign power systems and China's new-type power system,analyzes the development of the new form of power grid from four aspects:AC/DC hybrid power system,distributed smart grid,smart micro grid and smart distribution grid,analyzes and judges the risks and challenges of power grid security under a new type of power system.On this basis,the following proactive recommendations are proposed to enhance the planning and deployment of the power grid,improve the efficiency and overall resilience of grid resource allocation,promote the research and development and application of advanced technologies,and refine risk management measures.It is expected that these suggestions will provide a reference for improving the power supply capacity,safety,stability,and resilience of China's power grid.
