Abstract
Keeping in the mind of pulsed power applications, especially in defence sectors, the Superconducting Magnetic Energy Storage (SMES) system is proposed for a smooth and reliable power flow in the grid. Power Converter Unit (PCU) of the SMES system consists of a DC-DC converter and a three-phase voltage source converter along with a DC-link capacitor which couples both the converters. Particularly, the voltage across the DC-link capacitor is tightly regulated using a dynamic evolution based control strategy in the DC-DC converter. Consequently, the DC-link voltage is maintained almost constant with a voltage regulation of ± 5.26% during pulsed power load condition. Moreover, an effective pulsed power load compensation, and uniform voltage distribution across the SMES coil are achieved due to the precise solid-state control. Nevertheless, the performance of the proposed SMES system is conducted in the MATLAB software.
