AMEUR, Abderrahim; MERZOUG, Abelmalik
This study analyzes a hybrid off-grid energy system in Chlef, (El Hadjadj). It combines PV
panels (with various tracking systems), a diesel generator, and batteries. Four configurations
are assessed: fixed-tilt, HSAT, VSAT, and DAT, using MPPT optimization. HOMER Pro
simulations show DAT yields the most energy (37,788 kWh/year). The fixed-tilt at 38° is the
most economical (NPC: \$21,985; COE: \$0.0863/kWh). Results highlight the trade-off
between energy performance and cost for remote areas

MAKHALDI, MARWA
Ce mémoire présente un système de contrôle à distance d'un oscilloscope GDS via
Internet, conçu pour les travaux pratiques en laboratoire d'enseignement. L'objectif principal
est de permettre aux étudiants d'accéder à l'oscilloscope et de l'utiliser à distance, facilitant
ainsi leur apprentissage et la réalisation d'expériences pratiques sans avoir à être
physiquement présents au laboratoire.
Pour atteindre cet objectif, une interface web a été développée, combinant des
technologies telles que le Hypertext Markup Language (HTML), JavaScript, Hyper Texte
Preprocessor (PHP) et Python, afin d'assurer une communication fluide avec l'oscilloscope sur
le réseau via le protocole Standard Command for programmable instruments( SCPI). De plus,
des fonctionnalités de gestion des commandes et de récupération des données en temps réel
sont incluses pour offrir une expérience utilisateur optimale.
Les résultats démontrent que ce système permet un contrôle efficace et intuitif de
l’oscilloscope à distance, contribuant ainsi à moderniser l’enseignement des sciences
expérimentales et à répondre aux besoins des formations à distance, notamment en contexte
de digitalisation croissante de l’éducation.

BOUKECIAT, Bouchra; HIRECHE, Sabrina
The Synchronous Reluctance Motor (SynRM) is a robust and efficient AC machine
that generates torque through the variation of magnetic reluctance, without the need for rotor
windings or permanent magnets. This Master’s thesis investigates the modeling and advanced
control of SynRMs to improve their dynamic performance and robustness. A detailed analysis of
the motor's structure and its d-q frame model reveals strong flux–torque coupling, which
complicates control and necessitates decoupling strategies. A rotor flux-oriented vector control
approach is first implemented, yielding satisfactory results under nominal conditions but
showing performance degradation under parameter variations. To address these limitations, a
PID-based Super-Twisting Sliding Mode Controller (PID-STC) is proposed. This controller
integrates robustness, fast dynamic response, and reduced chattering. Simulation results confirm
its superiority over conventional PI and classical STC controllers in terms of precision and
disturbance rejection

YOUCEF ACHIRA, Chaimaa; BOUGHARI, Sarra
In recent years, the energy sector has witnessed a major shift towards adopting
renewable energy sources as a clean and sustainable alternative to conventional energy
sources. In this context, microgrid systems have emerged as a promising solution for
electricity generation and distribution, particularly in remote and isolated areas, due to their
independence and operational flexibility. However, despite their numerous advantages,
these systems face technical challenges, most notably frequency fluctuations resulting from
load fluctuations and the instability of renewable energy sources such as wind and solar.
This leads to deteriorating power quality and threatens grid stability. Based on this
problem, this work aims to enhance frequency stability and reduce frequency fluctuations in
a microgrid system operating under challenging operating conditions, such as sudden load
changes or reduced renewable energy production. To achieve this, a PID controller is
proposed due to its simplicity and effectiveness, with its parameters adjusted using the Ant
Colony Optimization (ACO) algorithm.
After building a model of the microgrid system and simulating its behavior using
MATLAB/SIMULINK, the simulation results showed that the PID controller tuned with
the ACO algorithm achieved excellent performance in reducing frequency fluctuations and
improving the dynamic stability of the grid.
