Řízení výkonu v solid state transformátoru – budoucí možné náhradě distribučního transformátoru

One of the main challenges of current electric grid not only in the Czech republic is the integration of an increasing number of small and often unpredictable power sources, especially renewable ones. Transition to so called smart grids which should be an answer to this problem includes almost all components of electrical grid. This means that in the future there will be also some smart replacement of a distribution transformer. A device called energy router contains a power part - so called solid state transformer (SST) which could be such a replacement of the distribution transformer. This paper presents how such a device could be carried out and how control of electric power in the SST could be performed.
