A Novel Hybrid Energy Storage Strategy Based on Flywheel and Lead-acid Battery in Wind Power Generation System

In this paper, based on expounding the basic structure and operating principle of the flywheel energy storage system, the maximum energy storage and energy efficiency of the flywheel batteries are analyzed. Research data shows that there is still a part of the energy left after the flywheel energy storage system doing the effective energy output. In the premise to save this part of energy for purpose, the way of combining the flywheel battery with lead-acid battery is proposed to put forward a new hybrid energy storage system. At last, the structure of the new hybrid energy storage system is designed for non-grid and grid wind power generation system.
