Application of Flywheel Battery in Solar Power System

A micro flywheel energy storage system was designed in which the flywheel battery saves and releases energy when necessary. Controlling system and four operating modes of solar power system containing flywheel battery were given and operating process of this system was simulated. The results show that: the flywheel battery resolves the problem of incapability of solar power supply at night and delays the time of supply. Output characteristics of photovoltaic cell are optimized in this system and the quality and the reliability in power supply is greatly improved.
