Abstract:
An electrical energy storage system for supplying power to a load comprising:a. a plurality of flywheel energy storage systems, each supplying a power output signal, each of said flywheel energy storage systems comprising: i. a flywheel turning at an initially predetermined rate; ii. a motor/generator coupled to said flywheel; iii. a bi-directional inverter circuit coupled to said motor/generator and to said load; and iv. a control circuit coupled to said motor/generator and said bi-directional inverter circuit for controlling said power output signal of said flywheel energy storage system; v. said control circuit being configured and arranged to control an actual output voltage of said power output signal responsive to a determination of an actual power output signal for said each of said flywheel energy storage systems and independently of the other of said flywheel energy storage systems; and b. a connector circuit connecting said flywheel energy storage systems to said load, said connector circuit not connecting said flywheel energy storage systems to each other.
