This paper proposes an adaptive output power control of superconducting magnetic energy storage (SMES) to solve the output power fluctuation problem of the grid connected hybrid permanent magnet synchronous generators (PMSG) wind and photovoltaic generations (HWPV). By the power control of SMES, the adaptive output power reference is employed to achieve the desired output power of the HWPV while the variation of SMES coil current is regulated between the minimum and maximum limits. Study result shows that the proposed adaptive power control of SMES is able to alleviate the HWPV output power fluctuation, and maintain the SMES coil current in the acceptable range effectively.
