The electrical power supply structure of today's power systems is changing towards high shares of renewable power supply. This leads to a decreased number of conventional power plants. However, conventional power plants still play a major role when it comes to voltage and frequency control. Thus, the remaining power plants in the system together with the renewable power supply units have to carry...
The transition of the power grid with fewer reactive power sources demands new solutions to locally compensate reactive power in order to reduce transmission losses in the extra high voltage grid. The capability of high voltage clusters to meet these requirements is evaluated in this paper taking different approaches into account. The feasible contribution of distributed energy resources to provide...
Owing to its advantages over the series resonant inverter particularly in the high power applications, a focus is made in this paper on the design and development of parallel resonant inverter for induction metal hardening. Performances investigation is made to highlight its features in term of power control using various techniques. Digital simulation is developed using CAD techniques and finally...
