Dynamic Voltage Restorer Based Solar PV System Connected Grid Utilizing UPQC with Fuzzy

Voltage stability in integrated photovoltaic (PV) distribution systems is crucial for enabling the efficient operation of all linked equipment in the distribution network. One of the most challenging aspects of PV integration is keeping voltage profiles stable. The primary focus is maintaining a constant 22 kVA load voltage profile. In the end, we settled on a PV integrated distribution system with a single phase. Combining a differential inverter with a dynamic voltage restorer (DVR) and a distribution static synchronous compensator (D-Statcom) is a first for the power conditioning sector (UPQC). The purpose of this innovative UPQC system is to employ a fuzzy controller to successfully connect a 10 kW solar PV system to the grid. Based on these results, the optimal battery-powered UPQC control strategy may be selected. As a means of increasing PV integration and ensuring voltage stability in the distribution network, a 20 kVA UPQC was constructed. Total harmonic dispersion may be minimised by maintaining a steady distribution system frequency, voltage, and reactance/resistance ratio.
