Performance of a Single-phase Grid-integrated Photovoltaic based DSTATCOM using Modified p-q Theory Control Algorithm.

Abstract

This paper investigates the performance of a single-phase grid-integrated photovoltaic based DSTATCOM by using modified p-q theory control algorithm. Previously, p-q theory controller has been employed for a three-phase DSTATCOM system. Thus, this paper employs a modified p-q theory control algorithm for a single-phase grid-integrated solar PV (GCPV) based DSTATCOM. Thus, the GCPV system has improved with DSTATCOM capabilities such as harmonic reduction for a single-phase distribution system under varying solar irradiances. The simulation results have been obtained by using MATLAB/SIMULINK software in accordance with IEEE Standard 519:2014, which stated that the THD should be less than 8% for the line current at the Point of Common Coupling (PCC). The performance of the single-phase GCPV based DSTATCOM has been analysed for dynamic and steady-state conditions under varying solar irradiances.

Assessment of a single-phase single-stage grid-connected photovoltaic system

“…However, the previous literature focused more on three-phase GCPV system. Despite the fact that a singlephase GCPV system is normally being used in small scale rooftop configuration connecting to low-voltage (LV) distribution network [13], [14], it also contributes towards the instability of grid system especially during high power penetration level.…”
