In this paper we present a new control strategy of wind turbine, by controlling the pitch angle that must be regulated to capture the maximum of power using PID controller and particle swarm optimization, the problem is to identify the PID controller parameters employing the PSO technique. This study makes a mathematical model, which is used to control the power characteristics of the turbine, a comparison...
One of the most commonly used control methods for three phase converters is the so-called Direct Power Control (DPC), which is based on an appropriate selection of converter switching states via predefined switching table. One important feature of Direct Power Control strategy is the variable switching frequency due to the absence of Pulse Widths Modulation (PWM) block. However, a PWM generator can...
This paper proposes a simple automatic technique for fault diagnosis in photovoltaic (PV) arrays, based on the analysis of the an omalies observed in the I-V characteristic. Firstly, the I-V characteristic of the PV array is simulated using Matlab/Simscape tool for different faulty conditions; which is experimentally validated by generating different faults on a PV string installed at the Renewable...
In this paper, Matlab/Simscape-based model for the simulation of photovoltaic (PV) strings under partially shaded conditions (PSCs) is presented. Parallel and series configurations of PV strings with different patterns of insolation have been investigated. It has been demonstrated that the electrical performance of parallel connected PV module in a PV string is less susceptible to the non-uniform...
This paper introduces the preliminary results of the simulation and implementation of PV array based on neural network and Hardware Description language (VHDL). In fact, an experimental database of meteorological data (irradiation, temperature) and output electrical generation signals of the PV array (current and voltage) has been used in this study. The inputs of the ANN-PV array are the total solar...
The number of electronic applications using artificial neural network-based (ANN) solutions has increased considerably in the last few years. However, the ANN- application in photovoltaic systems is very limited. This paper introduces the preliminary result of the modeling and simulation of photovoltaic panel based on ANN and VHDL-language. In fact, an experimental database of meteorological data...
