Novel application of electric energy storage using flywheel/SMES

Storage of electric power is the most important technology. The novel technology is explained about the flywheel which used mechanical energy, and the superconductive magnetic energy storage (SMES) using magnetic energy. As for the flywheel, the stabilization of the pulsation in the wind-power generation is promising. Furthermore, the pump up operation using a flywheel raises the efficiency of the wind-power generation. As for SMES, the idea of the electromagnetic force balanced coil which decrease electromagnetic force is shown. The problem of the high cost can be solved when it has SMES as a DC-L in the frequency change and BtoB interconnection facility
