Power Quality Improvement of Photovoltaic Distributed Generation System using Artificial Neural Network for Environmental Preservation

Abstract

Most of the economies are emerging with the growth in the renewable energy system. A solar photovoltaic system is one of the good sources of energy among them which provides clean and green energy. As it adds less pollution to the environment and hence advancement in technology of renewable energy system adds great effect on the environmental preservation. This paper describes a 1-ф photovoltaic distributed generation system having enhanced power quality features. Initially, the system has been implemented by using pulse width modulation-based switching schemes for the smooth control of the power flow between photovoltaic system, grid, and non-linear load. The system involves nonlinear current compensation and capacitor voltage balancing along with maximum power point tracking. Using this model, sample data has been collected for the training and testing of artificial neural networks. The artificial neural network was trained using the scaled conjugate gradient approach. The response of the neural network provides an estimated reference current for the controller to enhance power quality features. The inverter used in this work also acts as a shunt active power filter during night time. The system’s result is simulated and validated through MATLAB/Simulink.

“…To address the problem associated with carbon emissions and transmission losses, the world is gradually shifting to Distributed Generation (DG) systems that incorporate renewable energy resources [6,7]. The use of a DG system can assist electricity suppliers in meeting customer demand [8]. Distributed generating offers flexibility in adapting to changing conditions and efficient operation and maintenance [9].…”

“…The FCs are becoming a viable alternative to traditional energy sources. FCs technology is gaining popularity in research and will play an essential role in the coming decades [8]. In recent years, FCs have been progressively seen as a substantial component of micro-grids [7].…”
