Optimization of Network Security Management and Protection Mechanism in Smart Grid

Smart grids significantly improve the reliability, security and efficiency of power systems by integrating network and information technology with power systems. However, in a highly informatized and interconnected environment, smart grids also face increasingly complex and evolving cybersecurity threats. This paper mainly analyzes the characteristics and architecture of the smart grid, describes the common security vulnerabilities of smart grid network security from the level of network and data operation security, and puts forward an optimized protection mechanism in a targeted manner to enhance the overall security performance of smart grid. This paper expects to provide a theoretical basis for the security of the smart grid, so as to promote the safe development and application of the smart grid.
