Abstract
Power generation by renewable resources that are environment friendly has been attractive lately. However, it is a big problem that the output fluctuation from the renewable energy sources causes instability to the power network when they are directly connected to the utility grid. Although a power storage system is effective for compensating for the output fluctuation, this electric power storage system must have large capacity and quick response. We proposed an advanced superconducting power conditioning system (ASPCS) composed of two kinds of power storage systems. In this paper, we experimentally verified the validity of the compensating system for fluctuating output power using a superconducting magnetic energy storage and an electronic load instead of an electrolyzer. It was demonstrated that the ASPCS was effective for compensating for the output fluctuation of the renewable energy.
