Scientists of Tomsk Polytechnic University are conducting research on electromechanical transients in type-III and type-IV wind power plants, as well as their impact on the inertia of an energy system in general and algorithms of virtual inertia. The TPU scientists are intending to develop a methodology for adjusting automation devices to prevent emergencies taking into account the impact of renewable sources of energy on inertia change in the energy system. The research is supported by a grant from the President of the Russian Federation.

Conventional energy systems possess experience in proven power system protection, which allows controlling emergencies and responding to them on time. Electrical equipment (gas-turbine units, renewable energy systems) equipped in the modern energy systems significantly changes their dynamic properties, i.e. increases the speed of the process due to inertia reduction.

“The next types of wind power plants introduced in Europe and the USA in large scale make a less contribution to the total inertia of the energy system as they connect to the energy system via voltage converters. Over 50% of the German energy system is based on renewable sources of energy, while over 80% is in Denmark.

Over 50% of the German energy system is based on renewable sources of energy, while over 80% is in Denmark.

Although, wide-area stability control systems in such plants can be insensitive to rapid changes,” says Igor Razzhivin, Associate Professor of the TPU Division of Power and Electrical Engineering.

The TPU scientists conducted a series of experiments using a teaching model similar to the energy system of Tomsk Oblast. They simulated emergencies (short circuit, load shedding and so on) ranging the introduction level of capacity of the wind power plants. The experiments showed that after the introduction of the wind power plants in the energy systems, inertia could be decreased up to 50% depending on the introduced capacity.

“A popular method of risk calculation and estimation is mathematical modeling. There is a fundamental problem affecting the fidelity of process reproduction. Therefore, we used a TPU development in the research work, a multiprocessor hardware and software system entitled All-mode Real-time Simulation Facility of an Electric Power System. The construction principles of the model of the energy system which are laid down in the TPU development guarantee the fidelity of solution,” the scientist explains.

The scientists also conducted a series of experiments with the algorithm of virtual inertia, which overseas colleagues consider as a probable solution to decreasing inertia problems. The core of the algorithm lays in the synthetic maintenance of inertia due to an additional control system of voltage converters. The research showed that in case of a change of the capacity level and adjustment coefficients, the algorithm can show a negative effect.

“It is a relevant problem for Russia, as renewable sources of energy are gradually being introduced in the united energy system. Wind and solar power plants are currently being introduced in the southern part of Russia. There are plans to introduce plants of total capacity up to 1 GW (this capacity is equal to four state district power plant No. 2 in Tomsk).

The process of plant connection to the energy system is complicated and requires detailed prior research. Such problems related to inertia changes in the energy system and the problems of inertia changes are not solved in the Russian energy industry yet,” Igor Razzhivin explains.

The TPU scientists are intending to create a universal specialized accelerated processing unit, which will simulate and reproduce type-III and type-IV wind power plants and a solar power plant. Based on this model and the TPU simulating energy complex, the scientists will create a large energy system. Its advantage will become a hybrid approach: digital, analogue and physical simulation. Due to it, it will be possible to minimize an error and in more detail study the impact of renewable sources of energy on the energy system in general.

The research work is being conducted within the grant of the President of the Russian Federation and will last for two years. The staff of the TPU the Division of Power and Electrical Engineering: Associate Professor Igor Razzhivin and two postgraduates Vladimir Rudnik and Anton Kievets are conducting the research work.

Scientists of Tomsk Polytechnic University have created a concept of all-mode verification of calculations of modes and processes in smart grids, which is based on information from a model standard. Within the concept, they formed accuracy classes of mathematical models of modern devices of flexible alternating current transmission systems (FACTS) and high-voltage, direct current (HVDC) electric power transmission systems, as well as renewable sources of energy. It was required for complete and reliable solutions to practical tasks in power engineering.

Solving the problem of all-mode verification of information obtained in the result of numeral calculations contributes to increasing an accident rate, the most essential reliability and efficiency indexes of grid operation.

“According to the statistics of system accidents in the global power engineering, about half of these accidents are related to the use of ill-founded calculation data obtained using conventional methods of modelling. The situation is becoming worse because of the modern tendencies to complication of grids due to the introduction of renewable generation, FACTS and HVDC devices, as well as the change and complication of operation modes and processes in grids,”

explains Alexey Suvorov, Associate Professor of the TPU Division of Power and Electrical Engineering.

The scientists proposed to use the model standard of a grid to increase the completeness and reliability of calculations. A freely configurable developed multimodular complex for real-time simulation of grids of any dimensions and topology is used as the model standard. The complex was created due to a hybrid approach to modelling complicated dynamical systems, which was proposed and being developed at TPU.

The developed concept of verification based on the hybrid model standard is unique and does not possess any alternatives in the global energy industry. Using the concept, the scientists already formed the accuracy classes of mathematical models of modern devices of FACTS and HVDC, as well as renewable sources of energy. The research work was conducted within the grant of the Russian Science Foundation.

Students of the TPU School of Nuclear Science and Engineering became participants of the II Youth Forum “Russia-Africa: Nuclear Education for Sustainable Development”, which was held at the Peoples’ Friendship University of Russia (RUDN University).

The Forum was arranged by the Rosatom State Corporation and RUDN University within the agreement signed at the Russia-Africa Summit in Sochi in 2019. The event was dedicated to searching for new forms of cooperation in the sustainable development of African countries via the promotion of nuclear education, which allows implementing the potential of youth in high-tech areas of science and technology in resident countries.

Tomsk Polytechnic University became a coordinator of the thematic section “Nuclear Medicine Today and Tomorrow”. The students from African countries studying the program of Nuclear Science and Technology at TPU were speakers representing the university with their online reports.

Vladimir An, Professor of the Kizhner Research Center of the TPU School of Advanced Manufacturing Technologies, has been conferred the Ordre des Palmes académiques (Order of Academic Palms), the oldest French decoration that is conferred on civilians only.

Abdo Malac, Counsellor on Science and Technologies at the Embassy of the French Republic to the Russian Federation, conferred Vladimir on October 11.

The conference was held during the visit of the delegation of science attachés and counsellors on science and education of European countries headed by Laurent Bochereau, Minister-Counsellor and Head of Science and Technology and Other EU Policies Section of the Delegation of the European Union to Russian Federation. They met with university researchers actively cooperating with European colleagues, discussed promising research projects in biomedicine, the energy industry and green chemistry, as well as solutions to expand and strengthen the cooperation of Russian and European researchers.

In his welcome address, Laurent Bochereau emphasized the TPU professor’s contribution to cooperation development and strengthening of international research and academic contacts. He also thanked Vladimir An for the achieved results: jointly implemented projects, research articles, student training and young scientists.

The Ordre des Palmes académiques was established in March 1808 by Emperor Napoleon as a decoration to honour academicians and professors of the University of Paris. The Ordre des Palmes académiques has three grades: Commandeur (Commander), Officier (Officer), Chevalier (Knight). The decorations are conferred by the decision of the Minister of National Education.

The decoration is designed to distinguish the merits of staff of French ministers who are responsible for national and higher education. According to an offer of the Minister for Europe and Foreign Affairs of France, the order can be conferred on both French citizens living abroad and international residents who make an effective contribution to intellectual, research and cultural expansion of France in overseas countries. The Prime Minister of France affirms the candidate who will be conferred.

France is one of the main TPU European partners in research cooperation. Within agreements, TPU cooperates with 16 research and academic institutions, among which are Université Bourgogne Franche-Comté, the University of Bordeaux, the University of Technology of Troyes, the University of Orléans and others.

The TPU Professor Vladimir An became a Chevalier of the Ordre des Palmes académiques. For over 20 years, Vladimir has been developing and supervising research areas of cooperation between French research and academic institutions and TPU. These are double degree programs, travel grants for young scientists, internships of TPU students at French universities.

Recently, the TPU master’s degree student Maxim Titov has successfully defended his thesis under the professor’s supervision at Paris Sciences et Lettres University (PSL University). Maxim became the first participant of the planned network program between TPU and PSL University, which will allow TPU students to obtain two diplomas at the same time. Among the research interests of the scientist, there are properties and application of nanopowders, green energy and the hydrogen economy.

“I am grateful to the Government of France for that they found an opportunity to distinguish my work in this field. I am also grateful to my TPU colleagues with whom we work together in the development of international educational programs. A special gratitude I would like to express to Svetlana Tovchikho, the first Director of the TPU Russia-France Center. She was that person who brought me up to date, helped me to start and successfully continue the development of international relations. Moreover, I am grateful to the university for its approach to the development of educational connections. I hope that such decorations will serve to recognize the important role of TPU in the development of Russia-France educational contacts,” Vladimir An said.
