Research on the scientific direction of “modes of electric power systems and objects and their management” in 2021 aimed to develop mathematical and computer models of elements of hybrid power systems. Another aim is to create a digital model of the UES of Ukraine, operating with the insertion of direct current in the power district of Khmelnytskyi NPP in parallel with the power connection ENTSO-E, and investigate the modes of its operation. The method of regulating the active power of the automatic regulator, which produces control actions on the insert of direct current and on regulating blocks of Burshtyn TPP, has been proposed. Analytical materials on identifying problems and modern directions of regulatory and technical support for developing electric power engineering in Ukraine based on the Smart Grid concept have been prepared.
Proposals for the development of a strategy and roadmap for the implementation of international and European standards have been formed; a unified methodology for assessing the economic effect of the use of electric energy storage systems for the provision of various services for regulating the regimes of the UES of Ukraine has been developed.
Models and methods of considering the impact of increasing the share of renewable energy sources on the functioning of the UES of Ukraine and the market value of electric energy in Ukraine have been improved, computing software for adjusting microprocessor protection against measurements in intact phases in complex electrical networks of the UES of Ukraine has been developed.
Next year, research in this direction will be aimed at the development of models and means of improving the regime reliability of the united energy system of Ukraine with renewable energy sources, in particular, the creation of an integrated hourly model of the UES of Ukraine, which provides for a significant share of renewable energy sources in the structure of its generating capacities, development of a strategy and roadmap for the management of electricity systems and electricity markets in Ukraine based on the Smart Grid concept.
