Professor Marian Pasko obtained his D.SC. degree in 1994 from the Faculty of Electrical Engineering at the Silesian University of Technology, defending a thesis titled: "Selection of compensators to optimize the working conditions of one-phase and multi-phase voltage sources with periodical non-sinusoidal waveforms". The primary areas of his research are issues related to improving the power quality of electric systems operating in conditions of deformation of voltages and currents. His most important achievements include:
optimization of working conditions of the non-sinusoidal periodic real voltage source by means of LC one-ports;
application of LC one-ports in phase load symmetrization in n-phase systems with non-sinusoidal periodical waveforms; and
design of LC compensator synthesis algorithm. Dr Grzegorz
Benysek obtained his PhD degree in 1998 from the Electrical Engineering Department at the Technical University of Zielona Góra, defending a thesis titled: "An analysis of hybrid compensator systems for the filtration harmonic current in AC supply networks". On November 16th 2007 he obtained his D.SC. degree from the Faculty of Electrical Engineering, Computer Science and Telecommunications at the University of Zielona Góra, defending a thesis titled: "Improvement in the Quality of Delivery of Electrical Energy using Power Electronics Systems". From the beginning he was involved in two major research areas:
1. utilization of the FACTS in distributed electric power systems;
2. power electronics based arrangements for power quality improvement.
His most important achievements include:
design, development and experimental investigations of different types of the active power conditioners (filtration-compensation arrangements and FACTS, also on the base of multilevel-inverters);
completion of theoretical and experimental studies of considered active power conditioners which allowed the most advantageous selection from the point of view of implementation;
the universal control algorithm for active power conditioners assigned to both the symmetrical and non-symmetrical loads; and
elaboration of probabilistic based methodology for active power conditioners power rating selection in distributed electric power systems.
He also worked vigorously to inaugurate international cooperation with universities across Europe. The collaborations resulted in two research projects granted by the European Union, among others.

Power quality describes a set of parameters of electric power and the load's ability to function properly under specific conditions. It is estimated that problems relating to power quality costs the European industry hundreds of billions of Euros annually. In contrast, financing for the prevention of these problems amount to fragments of these costs. Power Theories for Improved Power Quality addresses this imbalance by presenting and assessing a range of methods and problems related to improving the quality of electric power supply.
Focusing particularly on active compensators and the DSP based control algorithms, Power Theories for Improved Power Quality introduces the fundamental problems of electrical power. This introduction is followed by chapters which discuss:
'Power theories' including their historical development and application to practical problems,
operational principles of active compensator's DSP control based algorithms using examples and results from laboratory research, and
the key areas of application for these methods and suggested practical solutions.
Power Theories for Improved Power Quality is a key study resource for students in engineering and technical degrees as well as a reference for professional and practitioners in the electrical energy sector working with power quality.
