Abstract. The increasing complexity of the problems of asset management and ensuring theoperational reliability of electric power equipment, which specialists have to reckon with at all stages of the life cycle, leads to the need to develop and implement digital twins. Based on the analysis of these problems, the goal and objectives of the work were formulated. An explanation of the terms and definitions used by the authors is given. The basic principles of developing the architecture ofdigital twins in the form of images, examinations and functions of their components are stated. General technical requirements for digital twins of electric power equipment are proposed. Thefunctions of digital twin users at all stages of the life cycle of electric power equipment are formulated.
Keywords: digital twin, electrical power equipment, design, testing, diagnostics, monitoring, simulation of physical processes, digital twin architecture, images, examinations, digital platform, software, database, mathematical model, artificial intelligence algorithm

Abstract. This work presents assessment of the adequacy and accuracy of mathematical model ofenergy storage system (ESS) based on the results of full-scale experiment in autonomous power system, which includes gas piston units, abruptly variable active load and industrial design energy storage system with a rated voltage 10 kV, a power 1200 kVA and an energy capacity 400 kWh based on lithium-ion batteries. The structure of the developed mathematical model of ESS for calculating transients is described. Comparison of the results of full-scale tests and calculations ofthemathematical model showed their qualitative and quantitative coincidence, enough for scientific and engineering studies of the operation of ESS in the power systems.

Abstract. A proposal on solution of the “locked-in power” problem by the example of Tatarstan Republic is the subject of this article. Investigations of electrical loads required for residential andpublic buildings in Tatarstan were carried out by Roselektromontazh association. They show that actual loads are lower than calculated under regulatory documents. As a result, power transformers suffer huge losses and the payback period becomes very long. The problem can be solved by updating the electrical load. This will result in remarkable economic impact due to reduction of declared power
values (locked-in power is lower), power transformer capabilities, feeding cable size and, consequentially, the investment cost of construction and operation.
Keywords: locked-in power, standby power, energy losses, energy efficiency, energy saving, energy saving system, normalized estimated load

Abstract. Demand side management is an important tool for ensuring the flexibility of the electric power systems, as it maintains and regulates the balance of generation and consumption of electric energy and has a system-wide effect, which is formed by lowering electricity prices for consumers and˜optimizing the load and structure of generating and electric grid capacities. The article considers the current state and prospects of development of demand side management, including taking into account such an important component as distributed generation. Its potential and the possibility ofusing various development mechanisms are evaluated.
Keywords: demand side management, electric power system, potential, prospects

Abstract. Electrostatic forces that originate between current- conducting wires and the sheath in either SF6 GIS three-phase busbar arrangements or in three-phase gas-insulated transmission lines are considered in this article. The formula of Coulomb force originating between parallel wires is
obtained. The article shows that Coulomb force varies with the frequency 100 Hz, contains the DC component, reaches 20 Nm in systems of 110-500 kV voltage class and may cause resonant vibrations. Theoretical conclusions have been proven by the finite-element simulation of electrostatic field.

Abstract. The article discusses the possibilities of analyzing the technical state of equipment by anartificial intelligence system and gives a scheme for collecting data on the operation of electrical equipment of JSC “Rosseti Tyumen”. The experience of organizing personnel training is shown as aguarantee of effective use of artificial intelligence systems. The practical results of the analysis ofchanges in the technical state of the equipment fleet, as a result of management decisions on diagnosing and repairing equipment using an artificial intelligence system, are presented. Theobservation horizon for the fleet of equipment was 20 years.
