Abstract
An electrical energy storage system for supplying power to a load comprises a plurality of flywheel energy storage systems, each supplying a power output signal, and a connector circuit. The connector circuit connects the flywheel energy storage systems to the load, but the flywheel energy storage systems are not connected to each other. Each of the flywheel energy storage systems comprises a flywheel turning at an initially predetermined rate, a motor/generator coupled to the flywheel, a bi-directional inverter circuit coupled to the motor/generator and to the load, and a control circuit coupled to the motor/generator and the bi-directional inverter circuit. The control circuit controls the power output signal of the flywheel energy storage system independently of the other flywheel energy storage systems.
