HYBRID WIND SOLAR GENERATING SYSTEM WITH FLYWHEEL STORAGE SYSTEM

Abstract

Energy Storage System (ESS) integrated with the wind systems can drastically smooth the intermittent generation through the storage of energy that can be used during periods of low generation and the energy generated at the end of the night or at the beginning of tomorrow (when demand is extremely low), it can also be stored to be dispatched during peak demand hours when wind production is much lower. The Flywheel Energy Storage Systems (FESSs), act as mechanical batteries, can store mechanical energy and exchange it to electricity through a bi-directional converter and an electric machine. FESSs have a large number of charge and discharge cycles that make them perfect for the integration of wind systems. They can significantly improve the mitigation of power fluctuations by using (MATLAB/SIMULINK). The main objective in this thesis is to develop a comprehensive control philosophy for enhancing the output voltage to introduce power smoothing method using energy storage system which is Flywheel, and to develop optimal sizing for flywheel energy storage system using General Algebraic Modeling Software (Gams).
