Adaptive power optimization method based power quality improvement on distributed generation system using unified power quality conditioner

Abstract

The transmission line carries high-voltage alternating current or direct newlinecurrent from specific power generation or distribution to specific Non-linear newlineloads or grids. The major problem is power quality swells, flickers, and newlineunregulated voltages, which has been examined as a challenging task in the newlinetransmission line. Therefore, to solve the power quality issue, UPQC-based newlineActive Power Filters (APFs) using series and shunt compensation were used. newlineThe photovoltaic with UPQC consists of a shunt and a series compensator newlineconnected to a common DC bus. The solar PV array is directly integrated into newlinethe series compensator DC ink of the capacitor through a reverse blocking newlinearchitecture shunt compensator connected in the load side direction newlineIn this study, voltage supply inverters and multi-level inverters are newlineused to reduce harmonic distortion, voltage, and voltage interruptions. Solar newlineelectrical circuits connect solar arrays in DC and AC distribution networks. The newlineDC DC boost converter is used to convert the PV array s DC output voltage to newlinethe voltage level in the DC link. The novelty of the algorithm is the application newlineof Linear Predictive Phase Composition (LPPC) and Resilient Direct Imbalanced newlineControl (RDUC) with photovoltaic systems to develop and solve power quality newlineproblems. newline
