The goal of this work is to size a photovoltaic pumping system built on a brushless DC motor and without accumulators, then to evaluate its cost by comparing the latter with a pumping system powered by a diesel generator for a system of irrigation in…

A dynamic mathematical model used to predict the performance of passive cooling system by evapo-reflective roof in buildings for hot arid climates has been developed. The cooling system consists of a roof composed of concrete ceiling and flat…

This paper presents the performances improvement of a doubly fed induction generator (DFIG) driven by a wind turbine (WT) using direct torque control (DTC). However, the major drawbacks related to DTC are high torque/flux ripples that produce…

The photovoltaic solar energy becomes more and more one of the most abundant and an alternative source of electric energy. But its efficiency is very low. For this reason, several Maximum Power Point Tracking algorithms are used to track de maximum…

Renewable energy, especially solar photovoltaic (PV) panels, have been widely integrated into energy systems, indeed, this technology is eco-friendly and available almost everywhere. However, these systems exhibit some challenges in regards their…

The shadowing of a single cell in string leads to reverse bias of the shadowed cell. The cell acts as a load instead of a generator in order to deal with this effect and the hotspots problems, this paper focuses on the design of bypass diodes…

 In this work, we propose a new directed digital signature scheme over a group ring whose security relies on the hardness of the discrete logarithm problem and the factorization search problem. This scheme is efficient as it requires very few…

In this paper, a new modified variable step P&O maximum power point tracking algorithm using Proportional-Integral-Derivative controller tuned by particle swarm optimization is proposed. The classical fixed step P&O algorithm has good…

This paper proposes a novel single sensor maximum power point tracking method for PV system composed of Solarex MSX-60W PV panel operating at variable atmospheric conditions and DC-DC boost converter controlled using the proposed MPPT that uses only…

The main goal of this investigation is to use the fuzzy systems of Takagi Sugeno (TS) for modelling the daily solar radiation data. The Takagi-Sugeno models are a non-linear techniques, defined by a set of If- Then rules, each of which establishes a…
