Digital substation is an important component in the technological control of electric power system. In the context of the energy sector digitalization and the development of electric power systems based on innovative tools and technologies, modern electric power facilities, including digital substations, must be viewed as complex integrated cyber-physical systems. The paper gives consideration to the structure of a digital substation from the perspective of a cyber-physical system. An analysis of the factors affecting the extent to which the functionality of a digital substation is reduced during cyberattacks, and the factors contributing to its speedy restoration is made.
