Reverse flow transition control mechanism with maximum power point controlling (MPPT) technique for solar PV application

Abstract

ABSTRACTSatisfying the growing energy demand with various power resources is one of the crucial areas. Most of the grid-based industries have come forward to install solar-based photovoltaic (PV) systems to lower energy costs. Due to its simple accessibility and streamlined panel structure of solar PV, this is widely used in many application environments. Maximum Power Point Controlling (MPPT) technique is one of the extensively used controlling techniques that use standard controls like Proportional Integral (PI) and Proportional Integral Derivative (PID) for power extraction. Some hybrid control mechanisms are used in traditional solar PV systems, limiting the issues of increased time consumption, reduced efficiency, and increased THD. For this purpose, this paper intends to develop a new controlling technique named Reverse Flow Transition Control (RFTC) with the MPPT technique to provide power output. Also, the Bidirectional Buck-Boost (BBB) is implemented to increase the efficiency of the controlling scheme. Moreover, this paper developed an optimization-based controlling technique for attaining a reliable converter, and controller design results are validated for the proposed controller technique.CO EDITOR-IN-CHIEF: KuoCheng-ChienASSOCIATE EDITOR: KuoCheng-ChienKEYWORDS: Photovoltaic (PV) systemreverse flow transition control (RFTC)bi-directional buck-boost (BBB) convertermaximum peak point Tracking (MPPT) Nomenclature AUPQS=Advanced Universal Power Quality Conditioning SystemBA=Bat algorithmBBB=Bidirectional Buck-BoostCCM=Continuous Conduction ModeFFT=Fast Fourier transformHVDC=High Voltage Direct CurrentLCL=Inductor-capacitor-inductorLLLAD=Leaky Least Logarithmic Absolute DifferenceMp=Maximum peak point of PVMPPT=Maximum Power Point ControllingP&O=Perturbation and ObservationPI=Proportional IntegralPID=Proportional Integral DerivativePOFO-SMC=Perturbation Observer-based Functional Order Sliding Mode ControllerPV=PhotovoltaicRES=Renewable Energy SourceRFTC=Reverse Flow Transition ControlSiC MOSFET=Silicon-Carbide Metal Oxide Semiconductor field-effect transistorSVPWM=Space Vector Pulse Width ModulationTHD=Total harmonic distortionVC1iC1=Voltage and current capacitanceVL1iL1=Voltage and current inductanceVpIp=Peak voltage and currentVpvipv=Photovoltaic voltage and currentVRsiRs=Voltage and current resistanceDisclosure statementNo potential conflict of interest was reported by the author(s).
