Abstract: The modern power industry needs to deal with the rapidly increasing demand for electricity and address environmental problems regarding sustainable growth. To this end, smart grids provide a comprehensive solution for next-generation power systems. Such a power information control system collects power information in real-time and yields optimum power generation control using different types of energy management systems. Owing to such characteristics a power information control system requires strong real-time information collection and control capabilities. Information collection and control properties are necessary because of the increased vulnerability associated with cyber security as opposed to existing information and communications systems. This study introduces a theoretical standard for the establishment of secure systems by analyzing the structure of the power information control system in addition to quantifying the risk of cyber-attacks that remain poorly studied.
