Research on Security Management and Control of Power Grid Digital Twin Based on Edge Computing

Edge computing and digital twin technology are two new digital technologies that are developing rapidly. Edge computing has become more and more widely used in various scenarios and smart terminal devices, adding more and more edge computing business sinking demands, making the distance between computing and users and data smaller and smaller, and digital twin technology provides a method of model interpretation for complex physical entities, provides new ideas for physical information fusion, and makes it applicable to various scenarios of physical entities and the virtualization model can achieve deep coupling. Nowadays, society’s demand for power grids is getting higher and higher. Therefore, the security protection of power grids is an important issue worthy of in-depth consideration. After the introduction of edge computing and digital twins and technologies, the relative vulnerability of power grids has been further characterized. By analyzing the security risks and characteristics of edge computing, and based on the edge computing security protection architecture, a power grid digital twin security control model including the application layer, function layer, model layer, data layer, and physical layer is constructed, so as to ensure that all aspects of the power grid are controlled. Layers of protection of structures and units ensure that the power grid can still ensure efficient and safe operation in an environment blessed by new technologies.
