Parameter optimization and sizing of flywheel energy storage system

In integration of renewable power the use of storage is gaining prominence and various types of storage and its combinations have been investigated in detail. Practical applications of storage require an accurate method for sizing them. This paper discusses a method of using an optimization technique to find the size of a flywheel storage device inertia required for smoothing the power output from a wind energy conversion system in addition to obtaining an efficient performance of the integral controller used to control the FESS. The objective of finding out an optimal inertial size of the machine and controller gain is achieved in this work.
