Real time implementation of MAD technique for single-phase SPV grid interfaced system

Abstract

This paper presents an application of adaptive control for the integration of single phase single stage solar photovoltaic (SPV) system to a single phase AC grid. The primitive of this integration of single-phase SPV system with the grid comprises of mitigation of harmonics, reactive power compensation and PFC (Power Factor Correction). It deals with a new mean adaptive detection (MAD) technique based on the adaptive detection method by eliminating the pulsating component present in the system. The employed topology consists of a VSI (Voltage Source Inverter) to extract the SPV power at good power quality and it feeds this power into the grid. Experimental results are recorded on a developed prototype of the SPV system in the laboratory to demonstrate the fast response of the control algorithm.
