The superconducting magnetic energy storage (SMES) device has been known as one of the most promising energy storage device as the superconducting coil shows almost zero electrical resistance. With a proper power conditioning circuit, it can have a super-fast unlimited charging/discharging cycle and handle a high pulse power. This feature becomes very attractive for power system applications as it can be utilized to solve the problems of voltage fluctuation, frequency deviation, and power supply disruption. This paper presents a novel concept for the integration of a low-cost micro-SMES (μ-SMES) unit with a residential photovoltaic (RPV) system to mitigate the solar photovoltaic output power intermittency. The low-cost magnesium di-boride (MgB 2 ) superconductor wire is used to design the μ-SMES unit. The performance of a 10-kW RPV-SMES is evaluated in the PSIM software environment.
