Experimental Validation of Solar Photovoltaic-Based Unified Power Quality Conditioner with Modified Power Angle Control Scheme

CODEN: JTEVAB

Abstract

This article proposes a modified Power Angle Control (PAC) strategy for a Unified Power Quality Conditioner (UPQC) with Distributed Generation (DG) for the viable interconnection of a Solar Photovoltaic (SPV) system into the network. The UPQC is composed of both shunt and series Active Power Filters (APFs). Shunt and series APFs are the standout among the best custom power devices, which gives compensation to current- and voltage-based unsettling influences distinctly. In the SPV-interconnected UPQC, the shunt APF supplies power from DG to the associated load, apart from providing a reactive power request, which prompts an expansion in the Volt-Ampere (VA) burden after its rating. The PAC scheme intends the successful use of series and shunt APFs through the sharing of reactive power to decrease the VA burden on shunt APF. The PAC strategy depends on an enhanced Synchronous Reference Frame that is equipped with a Second-Order Generalized Integrator–based Phase Locked Loop, which has simple calculations, is vibrant, and utilizes existing estimations of the SPV-incorporated UPQC. The execution of the proposed SPV-incorporated UPQC is examined with the presence of nonlinear and reactive burdens. The dynamic performance of the SPV-UPQC is checked under the grid disturbances, for example, voltage sag, swell, varying load, and change in sunlight-based light. The viability of the proposed control strategy is assessed through the digital simulation and equipment exploratory model results.
