Improved adaptive detection based control of grid integrating solar energy system

This paper deal with an improved adaptive detection (IAD) control approach for a grid tied solar photovoltaic (SPV) system. The SPV grid interfaced systems are facing several power quality issues due to extensive use of nonlinear and reactive loads. To eliminate these problems, an IAD based control approach for the proposed system is implemented for the mitigation of harmonics, reactive power and to improve power factor. The system topology consists of a VSI (Voltage Source Inverter) to extract the SPV power at high power quality and to feed it into the grid and IC (Incremental conductance) MPPT (Maximum Power Point Tracking) algorithm provides the maximum power extraction at various environmental conditions. To demonstrate the utility of the system, extensive tests are carried out on a developed prototype of single stage SPV-VSI integrated with the grid in the laboratory.
