Abstract:

In this paper, we propose a multidimensional dynamic risk assessment index system for the new system of virtual power plants. Firstly, based on the characteristics of the virtual power plant, a static risk assessment index system is built; a dynamic risk assessment index system is constructed, based on the evolution mechanism of attack paths, and collects data from information, physical and the information physical sides. Then, we propose a quantitative assessment method. Finally, the simulation experiment is carried out to validate the multi-dimensional dynamic risk assessment index system proposed in this paper, which can assess the network risk of the virtual power plant, identify potential risks, and propose valid enhancement measures.

Key words: virtual power plant, interaction between public network and private network, risk assessment, index system
