My research is focused on electrical power systems, their optimal planning, operation, monitoring, protection and control. Recently, I started a speculative research on integration of different energy systems. My career is predominantly linked to academia, however, in the past I have also spent 6 years working in industry (Asea Brown Bowery – ABB, Germany). Consequently, now I am combining both theoretical and experimental research, targeting complex research questions related to e.g. integration of renewable energy resources into existing power systems and reducing CO2 emission, as well as leading research on utilization of novel sensor and communication technology, application of complex science, data analytics, control and optimization theory, for optimal exploitation of future power systems. Finally, I am focused on validation of Smart Grid solutions using advanced hardware in the loop testing facilities. My research career gave me the opportunity to lead national and international research projects with a total value of 50+m US$. By joining Skoltech in 2021, I look forward to converting speculative ideas into practical solutions, contributing to reliable operation of energy systems/networks, the capital infrastructure ensuring a social prosperity at both national and international level.
All academic degrees at the University of Belgrade, School of Electrical Engineering, Serbia: 1) 1997 PhD, 2) 1993 MSc, 3) 1988 Dipl.-Ing., all in the field of Numerical Protection of Electrical Power Systems, with a focus on frequency estimation and adaptive underfrequency load shedding. In parallel, I was focused on modelling of electrical arc (check this one, too), its detection and application for protection of overhead transmission lines. Additional info about the nature of electrical arc (see VIDEO: Long arc in free air).
In my career, the following research topics were in the focus of my interest:

More about my research experience:
My research has always been based on the combination of theoretical and experimental science. These two have been supporting each other and synergically generated a new quality, particularly new research questions.
My very first journal paper published at the very beginning of my career was on fault location on overhead transmission lines. In this paper I successfully applied optimal recursive estimator, the Kalman Filter. Since then, I was often linked to the application of the Optimal Filtering Theory, in the first line estimators, linear and non-linear, trying to develop novel approaches for understanding the behavior of different power system components, or new algorithms for improvement of monitoring, control, or protective devices.
In my PhD thesis I presented a novel approach for frequency estimation, the Newton Type Algorithm. This was a non-linear estimation problem, offering to me a number of challenging questions, particularly with regard to development of efficient and robust methods for measurement of rate of frequency change and its implementation for Low Frequency Demand Control (also known as under-frequency load shedding). My estimators have been validated using real data records, which I have personally recorded in 1993 and 1995 in former Yugoslavia using simple 8-bit hardware architecture developed by myself.
During my academic stay in Germany in 1992 and 1993 at the TU Kaiserslautern, I was privileged to collaborate with the High Power Laboratory FGH-Mannheim (Forschungsgemeinschaft für elektrische Anlagen und Stromwirtschaft) on modelling of long arc in free air. A massive quantity of a high quality data records received from FGH-Mannheim supported my activities on arc modelling, the complex non-linear phenomenon, crucially important in a number of switchgear and power system protection applications. I am still working on arc modelling, now treating this challenge as an intellectual game, which has already generated a new formula for arc resistance, better understanding of arc elongation effects, highly accurate line protection algorithms suitable for protection of compensated lines, or mixed line-cable transmission corridors, novel approaches for short circuit calculation in distribution networks with renewable energy sources, new smart autoreclosure principle, models of short low current arcs suitable for development of new insulation materials, etc.
The above two research avenues requested an in depth understanding of fast and slow transient processes in power systems, so that my research was always strongly linked to high fidelity modelling and simulation of power networks. Today I am working on modelling of mixed ac-dc networks and in particular understanding the behavior of VSC-HVDC transmission systems, as well as Converter Interfaced Generation (CIG).
After spending 6 years in industry with ABB in Germany, my research approach has got a new dimension, the one which also started targeting practical solutions, the solutions characterized by a high Technology Readiness Level. Consequently, after leaving ABB in 2006 and moving to The University of Manchester, through strong research and consultancy links with the UK Transmission Network Operators/Owners and power products manufacturers, a number of my projects were determined by the actual industrial needs. One of major research activities, which is today the research area in which I am delivering the largest number of outputs became Wide Area Monitoring, Protection and Control (WAMPAC). This research area is overbridging the challenges related to emerging technology, needs of future power networks (including renewable energy sources, mixed ac-dc networks, energy storage technology, intermittency, uncertainties, etc.), or necessity for development of new Hardware in the Loop testing approaches and facilities like RTDS. As a result of a large scale capital grant, I managed to facilitate The University of Manchester with a 6 racks Manchester RTDS, which has been supporting a number of research projects which I was leading. Furthermore, my research included activities within the protection and control laboratory at Manchester, as well as implementation of complex science approaches (e.g. graph theory, or mathematical topology), traditional constrained non-linear optimization theory, computational intelligence (e.g. particle swarm optimization), computer science (in particular in designing new WAMPAC systems), system theory, optimal control etc. WAMPAC is today accepted as a typical Smart Grid concept.
After moving to Skoltech, Moscow, Russia in 2021, I kept working on hardware in the loop experimental work, supporting Smart Grid based solutions for future energy/power networks. As a PI of the prestigious Megagrant project, and the Head of newly established Distinguished Hardware in the loop laboratory, I continue working on research questions covering a broad range of Technology Readiness Level scale: from speculative and adventurous projects, to feasibility studies, patents, or practical solutions directly applicable in national and international industry.
One of my key research questions which I would like to answer in future is how to integrate the existing Energy and Distribution Management Systems and move from a classical approach in which the Smart Grid agenda has been split into two segments: a) Smart Transmission and b) Smart Distribution Grids. The idea of creating a Universal Virtual Management System, which as such might be applicable for all grid levels (Micro, Mini, Distribution, Transmission, Super, Mega-Grid) is currently attracting my research interests.
Over last five years I am exploring mechanisms of cascading outages and blackouts, targeting development of methods for the Strategic Management of Power System Blackouts, using Synchronized Measurement Technology and complex science. This work was strongly supported by National Grid, UK.
In 2018 I started a new research on multi-energy systems, searching for solutions how optimally to integrate ICT into the business cases related to this very important research and practical topic. This topic has led my new research interests towards the assessment of Big Data type problems and approaches for knowledge extraction. This is in line of my previous research topics related to the application of filtering/estimation theory in power systems.

On my research related to mathematical modelling of long arc in free air
Long arcs in free air occur during faults on e.g. overhead transmission lines. These arcs can be more than 10, even 20 meters long and the current flowing through it can be tens of kA high. In the following video, you will experience a slow motion of such an arc, recorded in FGH-Mannheim, Germany in 90s, when I was involved in a research on arc modelling and development of adaptive distance protection and autoreclosure for overhead transmission lines protection.
