Ultracapacitor Mains stabilizer

The ultra capacitor grid stabilizer is a combination of STATCOM converter for voltage stabilization and double layer capacitors for frequency stabilization. This enables an increased share of renewable energies in the grid without endangering grid stability. An increasing number of network operators in the European interconnected grid are remunerating the system services provided in this way accordingly, thus providing the basis for a viable business model.
