Self-Contained Power Systems with a Kinetic Energy Storage
Dependence of renewable energy sources on the climatic conditions during a year is one of the main problems associated with their utilization, a circumstance that does not allow the amount of energy produced by them to be predicted with sufficient accuracy and entails significant fluctuations of their AC power output, voltage, and frequency. The presently available technologies do not make it possible to achieve stable operation of power systems fully based on the use of renewable energy sources. High-qualityelectric power cannot be produced without parallel connection of conventional sources and energy storage systems. The article presents a review of foreign developments of kinetic energy storages used at hybrid power plants, and describes Russia’s first energy storage equipped with a magnetic HTSC levitation system with the energy storage capacity more than 5 MJ.
