Main R&D areas

Within the RESLab  research group, we address a wide range of issues of integration, operation, management and optimization of energy units with renewable energy sources, as well as the issue of energy management of buildings with RES. The main focus of the working group is mainly in the field of photovoltaic and wind power plants, hybrid energy systems, electricity storage and electromobility issues.

In our modern laboratory, we have a test facility for verifying the operating characteristics of DC / AC inverters, which consists of a programmable power supply, an artificial network with adjustable internal impedance, a battery storage simulator and a PV string simulator.

In the field of electricity storage, we solve the issue of design, setup and communication of BMS systems for lithium-based batteries, optimization of the use of lead batteries and the issue of flow-through batteries.

Part of the working group addresses issues related to the integration of fast charging stations for electric vehicles into the electricity network, including the integration of storage into power supply systems.

Working group is focused on network analysis, calculations and analysis of transient and steady states of power networks, static and dynamic models for simulating the operating states of distribution systems with elements of regulation, accumulation and distributed power generation. For these purposes, a number of modelling SW tools are used - PSCAD, MATLAB Simulink, MODES, SINCAL and also a physical model of a distribution network. In addition to our own research activities, we also prepare studies for our partners, which serve as a basis for the power system management, analysis and development.

Our team deals with the issue of power quality and low-frequency electromagnetic compatibility of power systems in the context of the operation of distribution systems and customer power networks. Within the group we organize specialized seminars and courses, we provide advice and consultation. We participate in the implementation of grant and private projects focused on measurement and management in distribution networks, integration of renewable sources, compatibility of appliances. Research is carried out in the field of above-standard measurement, detection of conditions and faults and testing.

The CVVOZE PowerLab group operates in two laboratories. The first one is a high current laboratory. Technology of the laboratory enables the generation of alternate currents up to a 150 kA magnitude at a 250 V voltage level and direct currents up to a 50 kA magnitude at a 1000 V voltage level. The second one is shielded high voltage laboratory that consists of three testing laboratories with different types of high voltage sources. The research infrastructure operates in an "open access" mode and can be used by researchers from non-commercial institutions around the world.

The Nuclear Power Group is engaged in teaching and research at the Institute of Electric Power Engineering in the field of nuclear energy, applied nuclear physics and dosimetry of ionizing radiation. Our group deals with advanced nuclear reactors, especially systems controlled by an accelerator or a high-power laser, we also study the issue of modern neutron sources or small modular reactors. An important topic of our work is also safety analysis of second and third generation reactors, we operate a unique facility M.R.C.H.A. (Mobile Research Critical Heat-flux Apparatus) capable of analyzing critical heat fluxes on smooth and treated surfaces or on samples of advanced nuclear fuel coverage. The device can also simulate the cooling of highly superheated nuclear fuel rods during an emergency. We also deal with calculations of the reserve for the boiling crisis in pressurized water reactors using subchannel codes, calculations of 3D kinetics or analyzes of uncertainties in assessing the safety of pools and containers of spent nuclear fuel. We cooperate with prestigious foreign universities and research institutes.

Our workgroup is focused on the research and measurement of modern light sources, the simulations of lighting and optical systems, the photobiological safety of light sources and luminaires, the development of new methodology for the indoor and outdoor discomfort glare measurement and evaluation. Furthermore, there is the development and testing of luminance analyser LDA in our laboratory that is capable of fast luminance measurement in the whole scene. Moreover, our workgroup carries out studies for our industry partners that are used as the design fundamental for the future development and evaluation of the modern lighting sources and luminaires. 

Our working group deals with the issues of protection, operation and safety of the power system. In the field of protection, the group specializes mainly in the development of new methods and systems for locating ground faults and the use of modern (centralized) protection systems and digitized data according to IEC 61850 standard (Sampled Values). In the area of ​​distribution system operation, research activities are focused on the issue of minimizing fault currents, autonomous regulation of distributed sources and the use of distributed metering for optimizing the distribution system operation. The last R&D area is focused on the evaluation of operational safety using probabilistic approaches, procedures optimization for the calculation of ground resistances and conditions for the compensated systems operation. We participate in the implementation of grant and purely private projects of mainly applied research in cooperation with electricity distribution companies, thanks to which it is possible to supplement a number of R&D activities by experimental measurements in real systems.

Our team deals with the issue of system wiring to control the indoor environment of buildings (lighting, shading, heating, cooling, ventilation). Within the group, we organize trainings, workshops, we provide advice and consultations. We participate in the implementation of intelligent building projects and the optimization of electricity consumption. Research is conducted in the field of effective control and optimization algorithms. We focus on KNX, Foxtrot, ABB Free @ Home and Inels.
