Performance analysis of a grid tied PV system

Abstract

The main scope of this paper is to investigate the performance of a single phase grid tied PV system. Novel control algorithm has been considered to control the inverter against the variations in the solar radiation in DG based systems either an autonomous mode or grid tied mode. In this paper, the characteristics of the inverter incorporated in the grid-tied system are discussed and the performance is analyzed. The effect of change in transmission line inductance & capacitance of the capacitor bank on Voltage, Current, THD, Distortion Factor, and Power Factor are observed and analyzed. Load compensation capability of the grid connected system when the system is isolated from the grid is analyzed. Actual power generated by the grid tied PV system is measured and compared with the predicted power generation of the system. All this analysis is useful to design a better converter controller for future power applications. The proposed configuration is implemented and the results are presented by making use of PV Grid Tied Training system.
