Investigation of Hybrid Renewable Energy Source and Hybrid Energy Storage System

Abstract

There are many renewable energy sources in nature today. The most commonly used of these are solar, wave, wind and flow energy. The weakest aspect of these renewable energy sources in nature is that the amount of energy produced depends on the nature conditions. The power generation capacities of these energy sources depending on the weather conditions in order to more stable them are necessary to combine. By combining more than one renewable energy source, a hybrid power generation system is created. Hybrid energy storage units are added to this hybrid power generation system to ensure persistence of energy. In this study, sea flow energy and offshore wind energy are combined and a hybrid power generation system has been created. In addition, a hybrid energy storage unit consisting of a battery and ultracapacitor has been created in order to ensure the persistence of the energy produced. All two hybrid units were simulated using MATLAB/Simulink program. By integrating these systems with each other, their dynamic behaviors were investigated under possible working conditions. The results of the simulation show that the hybrid energy storage unit supports the wind and sea flow energy.
