Mikhail Anders, a graduate student at the Faculty of Energy of Novosibirsk State Technical University (NETI) is developing a methodology for long-term planning and management of electric power modes of operation in the unified energy system. To solve this problem, the emphasis was placed on the use of direct current transmission.
The relevance of the study, according to the author, is due to the challenges faced by the Russian electric power industry: the problems of depleting generation resources and the capacity of electric networks, due to the active growth of electricity consumption. In the future, the formation of power-deficient power units is predicted. The Government of the Russian Federation has approved a document that defines the future of the electric power industry until 2042, and it has adopted several DC power transmission projects as ways to solve existing problems.
"High voltage direct current HVDC) is traditionally an effective way to transfer large amounts of electricity over long distances. However, it is important to note that this HVDC facility is a complex converter device based on power electronics elements. This provides many ways to change the technological mode of operation of such electrical installations, which makes them quite flexible in management. Being connected to an alternating current power system, HVDC can not only transport electricity over long distances, but also serve as an effective tool for controlling the operating mode of such an energy system," said Mikhail Anders.
A DC power transmission model is currently being developed to study its properties and operating modes as an independent facility, as well as a test AC power system, in which it is planned to evaluate the combined operation of two technologies — alternating current and direct current.
After developing and testing the models, the young scientist plans to start researching various modes of operation of the power system, determining effective strategies for managing the operating mode of the power system, and developing methods for calculating steady-state modes and transients in such power systems. The methodology is expected to be ready by 2027.
Mikhail Anders suggests that the results of his scientific work can be used at the design stage of real objects. The implementation of such projects requires a large amount of design, modeling, and testing resources before the object is integrated into the power grid.
