“…Dirt accumulation, aging, or manufacturing imperfections, etc., are also the sources in creating the mismatch scenarios. The dc/dc power optimizer (DCPO), which incorporates a dedicated converter for every panel, has been proposed by researchers to minimize energy loss during mismatch conditions [2], [5]- [8]. Each DCPO performs independent maximum power point tracking (MPPT) to mitigate the mismatch effect among the series-connected solar panels.…”

The photovoltaic (PV) system that is based on submodule-integrated converters (subMICs) is capable of maximizing solar energy harvest by eradicating power losses due to intrapanel mismatch. Modeling and simulation of subMIC-based systems are important to study the effect of PV partial shading, prove new control strategies, analyze distributed system dynamics, optimize system configurations, and determine system parameters, etc. However, the simulation of such systems can be very challenging due to the large number of switching-mode power units, nonlinear nature of PV generators, and complication of the coordinating control. This paper provides an effective solution to simulate and control single-phase grid-tied PV systems that are based on a practical subMICs configuration. The approach includes the simplified PV cell model and averaged model for power converters, which consider all dynamic interactions among the maximum power point tracking (MPPT), PV submodule voltage regulation, dc-link voltage control, and double frequency ripple. The effectiveness of the proposed simulation and the sub-MIC system is validated by the comparison with a practical system based on centralized PV inverter under the real-world solar irradiance and various PV mismatch conditions, e.g., partial shading and uneven temperature distribution etc.Index Terms-DC/DC power conversion, energy harvesting, photovoltaic power systems, simulation. 1949-3029

“…To obtain a photovoltaic generator the modules are wired in series and in parallel in order to get the operating voltage and peak power desired [10]. These series of modules are branches of the generator ("strings"); the number of modules per branch is determinate by its nominal voltage and the desired operating DC voltage.…”

In recent years the grid connected photovoltaic (PV) micro-generation facilities in individual homes has increased due to the adopted governmental policies and the industry attention. The power feed-in of PV generation in rural low-voltage grid can influence the power quality and the facility operation and reliability. This paper presents the results of a power quality analysis of a real PV generation facility connected to a rural low-voltage grid. The voltage fluctuations and the voltage harmonic content are observed and a statistical analysis and discussion are performed. The main achievements of the work are the statement of the disturbances imposed to the grid and its consequences to the technical and economic viability of the PV system. Keywords-distributed power generation, photovoltaic systems, power quality, voltage fluctuations. I.978-1-4799-6301-0/15/$31.00 ©2015 IEEE

Abstract-This work aims to develop an accurate model of an existing Photovoltaic Pumping System (PvPS) which is composed of an Ebara Pra-0.50T Asynchronous Moto-Pump (AMP) fed by Kaneka GSA-60 photovoltaic panels via a Moeller DV-51 speed drive. The developed model is then used to compare the performance of the system with its original control strategy based on classical indirect vector control strategy using PI speed controller and the proposed new control strategy based on Fuzzy Logic control technique for speed control and MPPT system. The obtained results of comparative simulations, induced in different dramatic variation of working conditions, show that the developed control strategy brought major enhancements in system performance.
