integrator" since DG systems have developed rapidly and are used in more applications. The shift up to high power DC converter technology finds increasing demand for power and necessary when converting low dc input voltage into greater dc output voltage, as is the case in applications like UPS, electric vehicles, and solar systems. Because the energy stored in the inductor is transferred to the load, causing the output voltage to always be greater than the input voltage, the output voltage of a boost converter, also known as a dcdc converter, is the sum of the input voltage and the voltage across the inductor. By adjusting the duty cycle with a PID controller, dc-dc converters may regulate the output voltage.
Abstract - : In the modern period, improvement in grid-
integrated solar power quality, Photovoltaic generation systems has been a rapidly expanding, and difficult. In the previous few decades, numerous methods for improving power quality have been developed. Reactive Power Compensation Techniques, DSTATCOM, Active filters, Dynamic Voltage Restorer (DVR), and Unified Power Quality Conditioner (UPQC) are some examples of this. In this study, the power quality of a grid-integrated solar Photovoltaic production scheme was improved using SAPF techniques. The Shunt Active power Filter (SAPF) with fuzzy logic and a DC to DC PID controller must be designed in order to progress the value of the power in a solar scheme integrated into the grid.

The availability of conventional energy sources has been decreasing and running out recently. Solar Photovoltaic (PV) systems are utilized as a substitute because they are easily available for free, are renewable, and have low running costs. However, by applying maximum power point tracking (MPPT) algorithms and effective converters to provide the greatest power output, problems like low efficiency and dependability on weather conditions are solved. Modeling and analysis of PV arrays, MPPT algorithms, and various efficient converters are done using MATLAB/Simulink [1]

1 .INTRODUCTION One of the most useful types of energy is electrical, which completely depends on the availability of power. As a result, the power quality is a critical aspect that is crucial for the efficient handling of user-side equipment. Power ranges for voltage and frequency play a role. The quality of power suffers if the variety deviates from the usual range
It is suggested to use a PWM inverter to improve power quality, specifically to lower total harmonic distortion (THD). Equipment performance and lifetime are affected by power quality issues. The THD produced by the nonlinear loads is decreased by this system. Because the existence of harmonics causes issues like overheating, insulation failure, etc. [2]
Semi conductor devices have undergone a significant advancement due to technological advancement. Semiconductor devices are essential in the energy sector because they make system control easier. The semi conductor devices, however, pull nonlinear current from the source because they themselves nonlinear. Reactive power and Harmonics are produced when nonlinear loads are used. Harmonics are seen as a serious issue with power quality .Harmonics must be removed in order to keep power quality and keep Total harmonic distortion below 5% according to IEEE 519 harmonics standard.
A boost converter based on PV that is governed by a closedloop PID system. After modeling the PV module in the MATLAB software, the duty ratio manage is established by a PID controller, and the PV unit is simply fed to the boost converter. [3]
The changeable dc output of a solar array must be transformed into a constant voltage and fixed frequency ac output that feeds into a grid via a photovoltaic (PV) system. This role of power conversion has been performed by power converters. A distributed generation system's power converter is an essential part, especially if it employs renewable energy. Power converters have changed from being a usual "power conversion device" to a "system
