Abstract
The environmental protection with power generation of an acceptable level of
reliability, quality and safety is the need of the modern generation. Recent
advancement in technology which includes effective power production and
simultaneous utilization of renewable energy resources. The rooftop installed
Photovoltaic (PV) system has gained much popularity due to the great potential to
supply clean energy with minimum impact on the environment.
The PV energy sources have discontinuous nature which leads to voltage quality
problems as well as the advancement of semiconductor tends to increase the level of
current harmonic distortion. Power quality issues at load side are the most common
problem which creates huge unbalance on transmission and generation side of the
system. As the problems related to power quality is going to take newer dimensions
power quality improvement technique of Unified Power Quality Conditioner is used
in the proposed thesis. The energy supply from PV is transferred to the Unified Power
Quality Conditioner (UPQC) for conditioning. Active Power Filter gives a promising
solution to compensate for the adverse effects of harmonics and reactive power
compensation by suitable control strategies. In UPQC, Shunt Active Filter is used to
mitigate current harmonics while the Series Active Power Filter has been used to
reduce the voltage interruptions. Integrating the photovoltaic array along with UPQC
has an advantage of pollution-free energy generation along with the surety of high
levels of power quality. Synchronous Reference Frame (SRF) is used as a control
technique with hysteresis based current control to obtain switching signals in the
shunt compensator while Phase Locked Loop (PLL) is used for series active power
filter.
To verify the objective of power quality, dynamic model of Confederated Three-
Phase PV-UPQC analysis is simulated in MATLAB-Simulink software under
different conditions. The performance evaluation shows that efficient results were
observed and considered effective for the system. The MATLAB simulation results
reveal that the designed Unified Power Quality Conditioner with photovoltaic array
effectively mitigate the current and voltage harmonics and is in compliance with the
IEEE519 recommended harmonic standards.
