Power Systems Research Group of TalTech

Research activities in the group are focused on the development of control and protection algorithms and applications, and performing system analysis considering the challenges in modern and future power systems. Key research areas: power system real-time control protection and analysis based on wide-area information with respect to HVDC and FACTS control, wind power integration, power quality and load modelling. Emphasis is on modern power systems where the level of generation through converters is increasing and consequently the level of system inertia is decreasing. Other research activities: the development and assessment of power quality mitigation methods in transmission and distribution systems considering the availability of modern compensation devices and wide-area information. Cooperation with companies is focused on carrying out multiple and important R&D activities related to power system planning and control challenges, e.g. system black start capability, optimal system control in future power systems, static and dynamic characteristics of the Estonian power system and reactive power planning in the Estonian power system. Main research outcomes: Development of - new methods and applications for power system, inertia and short-circuit power estimation for the use of wide- area measurements for power system analysis and control. - novel methods for power quality monitoring and assessment in transmission networks. - principles for modelling and analysis of Estonian power system black-start restoration process Electrical Power Engineering master’s level study programme and its enhancement in the field of ICT. Development and application of complex optimization methods for thermal power plants. Analysis of the operation of Estonian HVDC connections considering various future scenarios. Analysis and development of the power system wide-area protection concept in the scope of Estonian power system protection principles.
