Abstract

The unified power flow controller (UPFC) has been shown to benefit significantly from the contributions of photovoltaic (PV), according to the consensus between scientists. The power quality issues (PQI) and stability in real-world voltage sag/swell and harmonics have been significantly improved as a result of photovoltaic (PV) technology, as is evident. Additionally, there is a growing interest in the incorporation of photovoltaics (PV) into the electrical power system (EPS). In order to strengthen the stability of the situation, this generates a UPFC by employing the maximum power point tracker (MPPT) method. As a result, the MPPT technique’s objective is to determine the most effective means of reaching peak power. Consequently, the PV-UPFC technology has a significant influence on the PQI at the EPS in this manner. Using the PV-UPFC array, this article did an excellent job of modelling the EPS utilising the array. Furthermore, the 400-kW PV-UPFC farm is composed of four PV arrays, each of which is capable of producing up to 100 kW of power when exposed to 1k KW/s2 of sunlight. Remember that a single PV-UPFC array block is composed of sixty-four parallel strings. This is an important part of the equation. The alternative is that each string of PV-UPFC panels is comprised of five Sun-Power SPR/315E modules that are connected in series through the use of MATLAB-Simulation.
