This chapter proposes a new method for reconfiguring the dynamic photovoltaic (PV) array under repeating shade conditions. The repeating shades are often caused in photovoltaic installations, especially in residential installations where PV modules can be subjected to shades occurred by nearby buildings or trees. The proposed method is based on logic gates and aims to minimize the processing time in the way that controller does not have to perform an exhaustive calculations at each shade conditi...

When the panels in a photovoltaic generator (PVG) are subjected to Partial Shading (PS), some bypass diodes may turn on, and consequently multiple peaks in the Power -Voltage (P-V) characteristic are produced which reduces the output power. For an optimal GPV power extraction, one of emerging PS mitigation techniques is to reconfigure the PVG by altering the electrical connections between panels according to prevailing conditions. This paper presents a reconfigurable PV architecture based on irr...

Compared to conventional PV/T solar collector, the bi-fluid PV/ Ttype enables to extract more heat producing hot air and hot water and thus increasing the total efficiency per unit of area. The use of both fluids leads to provide a variety of PV/ Tthermal applications. In this paper, a mathematical modeling of a bi-fluid photovoltaic/thermal PV/ Tsolar collector type is developed and simulation was performed using MATLAB software. Furthermore, a performances comparison is carried out fo...

Dust deposition on the front of photovoltaic /thermal collectors presents greatest issues in some regions (desertic regions). It's considered as key parameter affecting much more collector's performances. In the present work, a particular attention has been paid to dust deposition effect on the electrical and thermal performances of photovoltaic /thermal collector PV/T.A model of sheet-and-tubes PV/ T collector is developed and validated with experimental data available in literature. The obtain...

This paper presents the modeling, control and optimization of a photovoltaic water pumping system. The system consists of a DC-DC Boost converter, which is used as a link between a Solar Photovoltaic (SPV) panels and the three-phase inverter (VSI) to feed the BLDC motor. A centrifugal pump is connected to this motor in order to use the water pumped afterwards to multiple applications. Maximum Power Point Tracking (MPPT) control techniques are an essential part of improving the efficiency of phot...

The partial shading (PS) effect on solar Photovoltaic Generator (PVG) is one of the main causes of losses in energy generation and reduced energy yield of the PVG. A promising technique for compensating these power losses relies on dynamically reconfiguring the electrical connections between photovoltaic (PV) modules via a switching matrix. This paper describes the hardware (HW) implementation of new equalization irradiance algorithm for reconfigurable PV architecture on a FPGA platform using Ve...

In the case of partial shadowing or photovoltaic (PV) module failure, the power provided by photovoltaic solar array significantly decreases. A promising technique to mitigate these power losses is based on the dynamic reconfiguration of the electrical connections between the PV modules. This article proposes a reconfigurable PV architecture based on Total-Cross-Tied (TCT) configuration and improved irradiance equalization (IrEq) algorithm. The PV architecture with the proposed optimization algo...

The efficiency of PV module is improved by combining a PV module and a thermal collector in one unit, resulting in a hybrid photovoltaic and thermal collector (PV/ T). The PV/ T system is a new solar and thermal technology which can provide simultanuously electrical and thermal energy. This kind of technologies can be used easily according to users demands. The aim of this paper is the design of an energy system based on PV/ T collector applied to a habitation. The proposed system in this study ...

Abstract In solar photovoltaic system, tracking the maximum power point (MPP) is challenging task due to varying climatic conditions. Moreover, the tracking algorithm becomes more complicated under the condition of partial shading due to the presence of multiple peaks in the power voltage characteristics. This paper introduces a novel method to track the global maximum power point under partially shaded conditions. The method combines an artificial neural network controller with a scanning algor...

This paper introduces a maximum power point method (MPPT) based on an artificial neural network (ANN) and a scanning algorithm. The proposed MPPT is applied to pumping system. The system is composed of solar generator, boost converter and centrifugal pump load driven by a DC motor. A complete simulation of the system is developed in MATLAB/SIMULINK under different weather conditions. The results obtained verify that the ANN controller shows a significant improvement in the power extraction perfo...
