Abstract

Nowadays, the grid-integrated superconducting magnetic energy storage (SMES) has received significant attention due to its short delay during charging and discharging process for stable operation of micro-grid. The energy conversion efficiency of the SMES mainly depends upon the switching algorithm of its power conditioning system (PCS). Traditional modulation techniques can cause considerable losses and poor conversion efficiency. In this paper, an advance pulse width modulation technique for an inverter for use with an SMES integrated with the single phase low voltage distribution grid is proposed, which provides a lower total harmonic distortion and reduced power conversion losses. The proposed technique improves the performance of the power conditioning system of SMES by reducing energy consumption from the SMES during short circuit fault, voltage collapse etc. The proposed algorithm is also verified in a laboratory test platform.
