With spreading of renewable energy in energy mix of national grids, the issue of high capacity and efficient energy storage is becoming very critical. A comprehensive model of South African power grid developed at the University of Pretoria is presented in this work. The model contains all notable power generators in the country. Mixed integer non-linear optimisation techniques are employed for unit...
Recent developments in flywheel technology opens new possible applications. Connecting flywheels and wind generators is not a new idea. However, flywheels were always considered as a short time compensation of stochastic output variations of wind generators instead of fully fledged means of energy storage. In this study connecting a wind farm with a flywheel system containing a number of flywheel...
