Research on the application of superconducting magnetic energy storage in wind/photovoltaic generation system

Because of the renewable energy generation (for example wind and photovoltaic) becomes a new research hotspot, people pays more attention to the problem of power fluctuation of wind/PV (photovoltaic) generation as the wind velocity and solar insolation intensity are intermittent and unpredictable. To solve the problem, this paper introduced superconducting magnetic energy storage (SMES). Compared with other energy storage, SMES is more suitable for the renewable energy generation system for its prominent merits like: a high power density, a high speed and high efficiency of charge and discharge, etc. The simulation model of a hybrid generation system which SMES combines with wind/PV generation is set up.
