RESULT ANALYSIS OF POWER QUALITY IMPROVEMENT FEATURES FOR GRID-CONNECTED SPACE VECTOR PULSE WIDTH MODULATION FEATURES

Abstract: This paper presents Space Vector Pulse Width Modulation scheme to enhance the power quality and responsibility of the microgrid system. The planned scheme is comprised of two inverters that allow the microgrid to exchange power generated by the distributed energy resources (DERs) and in addition to compensate the local unbalanced and nonlinear load. The planned scheme has increased responsibleness, lower bandwidth demand of the most inverter, lower cost as a result of reduction in filter size, and better utilization of microgrid power whereas using reduced dc-link voltage rating for the most inverter. These choices build the SVSI scheme a promising option for small grid provision sensitive hundreds.
