The paper considers approaches to the creation of intelligent energy systems based on WAMS monitoring systems, using information technology in metrology, in the means of receiving, processing and transmitting information and determining parameters in control tasks. The paper analyzes the existing cyberattacks on the SCADA and WAMS system and considers possible ways to solve control problems in terms of information security violations of intelligent energy systems. DoS-attacks are considered in more detail, which lead to the failure of devices that measure currents, voltages and capacities, as well as to the disruption of information processing equipment. The paper proposes an algorithm for estimating the state of cyber defense of the intelligent energy system based on mathematical modeling of the internal states of the system, which allows to obtain the required accuracy of calculations in terms of incomplete information, which is the inability to access measurement data.

And Control

The modeling and sea trials of the Unmanned Trimaran Vehicles (UTSV) are presented in this paper. For control design, six DOF dynamic modeling of autonomous Trimarans is presented. The detailed mathematical modeling is intended to provide the appropriate framework for a control design which explicitly addressed the six DOF UTV dynamics. A control system was developed based on backstepping to guide the vessel to track desired trajectories based on the input of the sensors. Physical experiments were conducted to determine the maneuvering property of UTV.

Model Approach

The article is devoted to the consideration of “digitalization” concept as a tool for solving control problems. The problems of digital twins formation are discussed and two directions for digital models creation are presented. The necessity of using a natural-model approach, methods of natural-mathematical modeling, similarity theory for building digital models is noted.
