Improvement in the Quality of Delivery of Electrical Energy using Power Electronics Systems
Electrical power is ubiquitous and continuously increasing in demand, with the result that power systems often operate close to their stability and thermal ratings. In order to tackle this problem, extraordinary changes are now taking place in the electri

Foreword
This book of the author G. Benysek is an important work for the development of the electric transmission system towards a more flexible technical system. Power transmission in electrical networks is essential for industrial and private consumers. The permanent reliability and stability of energy delivery is an obvious issue in all industrialised countries. Technical handling of the transmission system follows up to now well-tested approaches. Requirements for the adaptation of the power system result from the change of the energy supply itself. Due to increasing efforts for environmental protection at one hand and limited hydrocarbon resources on the other hand, conventional power plants with fossil fuels will be reduced significantly in future. The energy delivery is then realised by a remaining distributed generation from fossil fuels and increasing power shares of renewable power plants. Hence, the management of the energy transmission has to be adapted to the new situation. Several power flows will occur independ
