One of the main problems of introducing energy systems using renewable energy sources is its dependence on climatic conditions during the year. The instability of incoming energy leads to significant fluctuations in power, voltage and frequency of alternating current in the network. Modern technologies do not yet allow achieving sustainable energy systems, which are driven only by 100% usage of renewable energy. Nowadays production of high-quality electricity is possible with parallel connection of traditional sources and using energy storage systems. This article presents design solutions for application of flywheel energy storage systems (FESS) in autonomous energy systems used by foreign companies. We describe the design of superconducting FESS with magnetic HTS suspension with stored energy of more than 5 MJ, which is the first in Russia.
