A novel equivalent circuit-based model for photovoltaic sources
This paper presents a novel circuit-based model of photovoltaic (PV) source (cell, module or array) that can be easily integrated into any circuit-oriented simulators such as PSpice, PSCAD/EMTDC, PSIM, PowerSys of MATLAB/Simulink, etc. This proposed model is able to simulate accurately any commercial PV module behavior either exposed to uniform or non-uniform irradiance distributions. Moreover, it can also simulate perfectly PV arrays behavior in large scale PV systems. It is mainly derived from the conventional one-diode equivalent circuit model, which consists of a current source, a diode and two resistors. By modifying the linear part of this latter and including implicitly the effect of weather parameters (irradiance and cell temperature) on the circuit elements, our proposed model will encompass two types of dependent sources (voltage and current sources) and two resistances. To validate the truthfulness of the proposed novel model, comparisons between simulated and outdoor measured I-V characteristics on commercial PV module are done. Preliminary results have shown promising outputs and accuracy of this model.

MPPT Performance Analysis using an Online Measurement Method with an Outdoor Monitoring
This paper is intended to contribute to the conceptual design of an electronic helping tool to analyze the performance of maximum power point tracking systems(MPPT). Indeed, the MPPT is a device ensuring the connection between the PV generator and the rest of the PV conversion chain in order to extract and transfer the maximum of the electric power. In this work, we present a new method in analyzing MPPT performance witch the principle is based on the comparison of the maximum power(Pmp) that can be generated by the PVG and the power transferred to the DC load by the MPPT system. The measurement of these powers is realized outdoor with an online mode; i.e., the PV conversion chain is maintained in operation. The Pmp value obtained by measuring the couple (Isc, Voc). In this paper we will present the hardware implementation of the proposed technique. The measurement of climatic parameters such as, solar radiation and cell temperature are not taken into account, which characterizes the peculiarity of this method. Keywords: PVG, Maximum power, MPPT, Online measurement, Analysis.

Fault Tolerant Control Based on Adaptive Fuzzy Sliding Mode Controller for Induction-Motors
In industry, the service continuity of an electrical system drives requires degrees of reliability of operation and high safety. Thus, the system requires robust elements to avoid falling into the defects. But the appearance of defects, it is inevitable. It is therefore necessary to solve this problem by developing a control technique that can ensure continuity of operation in the presence of faults. Indeed, the sliding mode adaptive control based on fuzzy logic ensures the stability of the system healthy and able to compensate certain types of defects: the defects of low severity. In fact, is with the fuzzy sliding controller with varying control gains. This one is based on supervisory fuzzy inference system using the adaptive tune in order to improve the performance of controller in presence of current sensors faults. In addition, the sensors are the most sensitive elements and the seat of frequent faults, and play a leading role in the closed loop control. An operation of a tolerant control the default intended to compensate the default offset sensor. The developed algorithm is validated by simulation and the obtained results showed the effectiveness and the robustness of the proposed approach under different scenarios.

Modeling and simulation of photovoltaic array with different interconnection configurations under partial shading conditions for fill factor evaluation
Partial shading of a photovoltaic array is the condition under which different modules in the array experience different irradiance levels due to shading. This difference causes mismatch between the modules, leading to undesirable effects such as reduction in generating power and hot spots. The severity of these effects can be reduced by changing module interconnections of a solar array, three different interconnections configurations, series-parallel (SP), bridge-linked (BL) and total-cross-tied (TCT) of photovoltaic generator are studied using simulation models to compare their performances, also studied their characteristic parameter variation in the function of shading, with a special attention to: Open circuit voltage (Voc), Short circuit (Isc), Maximum power (Pmp) and fill factor (FF) evaluation, in order to find which configuration is less influential to partial shading effect.
