Abstract

This paper proposes a method to determine the optimal size of superconducting magnetic energy storage (SMES) to improve the stability of distribution power system with photovoltaic (PV) generation. The output power of PV system fluctuates according to changing weather conditions. Then, the system is subject to be unstable. In order to improve its stability, the SMES is applied. In general, the SMES is being considered as a strong candidate among energy storage devices in industry due to its high efficiency, fast response, and high energy density. To select the optimal size for SMES, several factors such as the output power fluctuation, the peak load shaving, the efficiency of converter for charging and discharging operation, and the voltage regulation for grid-connection, etc., are considered. Then, the performance of SMES with its optimal size is evaluated by the case study with the field measurement data of the irradiation and PV module temperature.
