The main components of the energy systems are generation, transmission and distribution, the latter among these three parts represents the most crucial infrastructure in terms of impact on reliability, quality and cost of electrical energy. Distribution systems, which traditionally have a radial or weakly meshed topology with a high ratio (R/X) in the lines and a unidirectional power flow, are not designed for the connection of decentralized production devices, but in recent decades these systems have profound changes have contributed to the transmission of these networks from a large centralized generation to the integration of additional decentralized sources, called Distributed Generation with relatively limited production capacities connected to distribution systems near the points of consumption. Therefore, in emerging electricity distribution networks, the important role of these sources can be clearly predicted. The Optimal Integration of Distributed Generation (OIDG) at the distribution level that is attracting increasing interest has many advantages, and currently plays a central role in the planning, operation and optimization of modern distribution systems. The specific problem to be considered in this thesis is that of the selection of the location, the volume and the technology of the units of DG, in order to minimize or maximize a predefined objective function (reduction of losses, improvement of the voltage profile, maximization of voltage stability, ... etc.), without violation of technical and operational constraints. In this context, the main contribution of this thesis is to improve the performance of power distribution systems through the study and development of a modeling and simulation framework ensures optimal integration of the units of the GD into power grids. radial distribution (RDR). In this thesis, an efficient approach based on a metaheuristic algorithm is adopted for an optimal integration of the distributed generation in the radial distribution systems (RDS) allowing to reduce the losses of active power; maximizing the voltage stability and improving the voltage profile. The approach adopted in this thesis applies to standard distribution test systems, 33 , 69 and 85 bus, various case studies are examined, some interesting results are also analyzed and discussed in this study.

detection is constantly evolving. Currently, these sensors are the largest segment of the
MEMS market. They are found in many areas as the first element of the measurement chain.
The main goal of thesis in hand is to study and model the thermo mechanical
behavior of these sensors. We have begun our work with a bibliographic study on the state of
the art of these devices, giving some concepts on the mechanical and physical properties of
the material used in the realization of these sensors. Then, we have studies the deflection at
the center of the membrane and the normal stress acting on its edges as a function of pressure
and temperature at rest. In addition, the effect of doping and temperature on the output
voltage of the sensor and the influence of the configuration of the gauges were also studied.
Given that the increase in temperature causes considerable drifts in the output
voltage, which are due not only to the manufacturing process but also to Joule heating, this
prompted us to devote a whole study to the thermal drifts generated by this effect in the
piezoresistive pressure sensors. We have described the influence of the supply voltage, the
operating time and its geometric parameters on its output characteristics.
The obtained results confirmed that the low polarization voltage should be applied to
dimensions of the membrane and to the length of the piezoresistive element. On the other
hand, the results showed that the self-heating is substantially reduced during a short operating
time of the device and the temperature assumes a steady state value beyond 100 min and
becomes independent of time.
In order to evaluate the reliability of the sensor, we have coupled the obtained
expression with that of the KANDA to evaluate the piezoresistivity coefficient π44 and the
sensitivity as a function of the bias voltage and the time operation of the device. The results
showed that π44 and the sensitivity to pressure are inversely proportional to the supply voltage
and the operating time, they are proportional to the length of the diaphragm. Finally, in the
last part of this thesis, a study is devoted to optimizing the performance of capacitive pressure
sensors.Diplôme : Doctorat en sciences En ligne : ../theses/electronique/BED7042.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10558 Etude, modélisation et simulation thermomécanique de capteur de pression au silicium [texte imprimé] / Abdelaziz Beddiaf, Auteur ; Fouad Kerrour, Directeur de thèse . - جامعة الإخوة منتوري قسنطينة, 2017 . - 119 f. ; 30 cm.
