The procedure of selection of flywheel energy storage as an autonomous power source

The market of f lywheel energy storages is widely represented by various devices with different characteristics and areas of application. However, there is still no standard procedure of f lywheel storage devices selecting, which could be unifying to several analytical expressions. The stock-produced f lywheel energy storages selection is solved by determining the number of f lywheel modulars and the mode of their operations during discharge. The article proposes a f lywheel energy storages selection procedure according to the principles of the power and energy balances of the system. The selection criteria basic expressions are obtained in general form. Numerical examples of the choice of storage devices with cascade and parallel discharge modes are considered. The selection criteria of f lywheel energy storage system with cascade operation mode is reduced to optimization task, for which the objective function, boundary conditions and a constraint system are defined. The numerical solution is obtained using the Solver of MS Excel.
