Photovoltaics (PV) is considered as one of the most expected renewable energy sources to be developed more economically and superconducting magnetic energy storage(SMES) is also expected to be put into power grid in the near future.
To get a reliable and easily controlled power source using PV, the hybrid system with SMES is desired because of the high efficiency, reliability and quick response characteristics of SMES as a power storage equipment.
In this paper, we propose a conceptional configuration and operating algorithm of PV-SMES system on the assumption that it would be connected to the power grid for commercial use. Considering the load leveling function of PV-SMES system, an optimum daily operation scheduling method of power systems which includes unit commitment and economic load dispatch is presented. The various features of PV-SMES system, such as, load leveling, operating cost reduction effect, smoothing effect of PV output, etc., are demonstrated and confirmed through simulation results for a model power system.
