Design, development, and implementation of grid-connected solar photovoltaic power conversion system
摘要： In this paper, a detailed documentation revealing the design, development, and implementation aspects of grid-connected solar photovoltaic (SPV) power conversion system is presented. Since the inverter is considered as a key constituent of an SPV system, a laboratory developed three-phase four-legged (3P4L) inverter is employed to diminish the overall cost of the SPV system considerably. The multifunctional inverter controlled SPV system proposed in this work not only injects active power into the electric grid, but it also serves as an active power filter (APF) to provide various power quality (PQ) solutions. This typically includes source current harmonic attenuation, load reactive current mitigation, neutral current elimination, source current balancing, in addition to ensure unity power factor operation. A various hardware circuits including signal sensing circuit, signal conditioning circuit, pulse amplification and isolation circuit, and blanking circuit are fabricated and assembled to develop a complete laboratory prototype model. In addition, the voltage and current controllers, the synchronize reference frame theory (SRFT)-based approach, and the phase-locked loop (PLL) control algorithms are embedded in dSPACE 1104 control platform. Furthermore, an STM32F407VGT microcontroller is employed to implement the incremental conductance based maximum power point (MPP) tracking algorithm. The effectiveness of the developed SPV system is first simulated in MATLAB/Simulink software. In the second step, the efficacy of the proposed configuration is investigated under balanced and unbalanced nonlinear loads on a laboratory developed prototype.

[IEEE 2018 International conference on computation of power, energy, Information and Communication (ICCPEIC) - Chennai, India (2018.3.28-2018.3.29)] 2018 Internat2018 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC)ional conference on computation of power, energy, Information and Communication (ICCPEIC) - Modified SEPIC Converter Based PV Inverter for Power Quality Improvement
摘要： Now a day the photovoltaic (PV) age is continuously notable, while require significantly more high-control quality. One PV generator providing to nonlinear burdens is wanted to be consolidated with a limit as an Active Power Filter (APF). In our errand, a three-arrange three-wire system, including a bare essential PV generator, modified single completed fundamental inductor converter (M-SEPIC) for high voltage change is sketched out. Furthermore, to separate greatest radiation control a most extreme power point following, calculation is utilized. Here a dc/air conditioning molding voltage source converter to go about as an Active power channel (APF), is proposed. The incite control speculation is utilized to design the PV-APF controller, which shows tried and true displays. Space vector direction (SVM) control system is used as a piece of the PV-APF controller for better execution.
