Abstract-As time goes on, developments in technology
occur dramatically. The Grey Wolf Optimized Control Methodology for Converter in Grid-Tied PV System is demonstrated in the present investigation. A new algorithm for an optimization problem develops every day. The present study implements an optimization-based Tuned PI controller, commonly referred to as the Grey Wolf Optimized (GWO) Algorithm, to improve power quality in a distribution system by means of converter control in a grid-tied photovoltaic system. The MATLAB/SIMULINK environment is used to model the complete system. Finally, this work highlights how a Grid Converter's GWO-tuned PI controller can improve power quality by minimizing THD. Keywords: Grey Wolf Optimization, PI Controller, Grid Tied Photovoltaic System, MATLAB/SIMULINK, STATCOM, Grid Converter, Duty Cycle.
1.INTRODUCTION
Converter's GWO-tuned PI controller can improve power quality by lowering THD [10]– [15].
2.GREY WOLF OPTIMIZATION (GWO) The GWO algorithm mimics the leadership hierarchy and hunting mechanism of grey wolves in nature. Four types of grey wolves such as alpha, beta, delta, and omega are employed. In addition to the social hierarchy of grey wolf’s pack hunting is another appealing societal action of grey wolves. The main segments of GWO are encircling, hunting and attacking prey.

The energy sector is now an essential component of organization for the well-being of nations and is also vital for economic development. The power sector in India is extremely changed. In India, conventional electricity production accounts for most power generation sources, with non-conventional generation seeing an increase in demand [1]– [5]. It is necessary to produce high-quality power since power generating is so important. However, there are various power quality problems because of the wide variety of loads. Power engineers and the power industry thus face a difficult problem when it comes to power quality. Many techniques are being used these days to compensate for power quality [6]– [10]. This article uses a grid converter based on GWO as a compensator to improve power quality. A shunt compensator called a Grid Converter (STATCOM) receives its input from a PV system. The Grey Wolf Optimized (GWO) Algorithm based control technique for the converter in a grid-tied photovoltaic system has been demonstrated in this study. A novel optimization technique is suggested for the STATCOM control system to fine-tune the PI Controller. Lastly, this work illustrates how a Grid
