Abstract
The article covers the study of measures aimed to improving the reliability of electrical power systems at the present stage. It considers the integration of the global electricity industry. The article analyzes the latest technical work in the field of automation, such as Smart Grid and intelligent power systems.
Highlights
Patterns of changes in the conditions for the development and functioning of electric power systems (EPS) lead to significant transformations in the structure of systems and their modes of operation. These transformations are caused by a number of objective factors that determine the shape of EPS of the future
They continue to increase the scale of EPS, expanding the territories they serve, uniting various EPS for joint work with the formation of interregional, interstate and intercontinental energy associations [1,3,4,9]
The proposals given in this article open the prospect of further research on an extremely important problem in assessing the reliability and safety of energy facilities and systems
Summary
Patterns of changes in the conditions for the development and functioning of electric power systems (EPS) lead to significant transformations in the structure of systems and their modes of operation. The development of electric power transmission systems in the world is characterized by their significant complication, increase of their intellectual level, the active introduction of renewable energy sources (RES), distributed generators, end-users with controlled consumption, as well as communication systems and control systems These changes are designed to provide benefits, such as the ability to meet the objectives of the state policy to diversify the electricity industry and provide consumers with greater choice while ensuring their own electricity supply [2]. Smart Grid refers to the modernization of the power supply system aimed at the ability to monitor, protect, optimize the functioning of all elements of EPS centralized and distributed generation, high-voltage transmission and distribution networks, industrial consumers and building management systems, energy storage devices, end-users, electrical transport, household appliances [17]. Technical Committee 57 of IEC develops international standards (Fig. 4) for EMS, SCADA, automation of distribution networks, information exchange, real-time control, etc., which will be used in the planning, use and operation of the IES [20]
