Several papers deal with the topic of multi-agent solutions for the energy management in complex energy systems. According to the time scale, we distinguish two kinds of management: a reactive management (short-term) and an anticipative management (long-term). The objective of this paper is to propose a survey of the different multi-agent approaches, we thus propose a classification of existing management approaches according to the level of the system at which the decisions are made. The physical deployment of services' steering shows that these services can be only of two types: independent and interdependent and gives hints about the adequate tools of management.

In this paper, we develop a study concerning the distributed generation of electricity using wind power. We propose a mathematical modeling and a simulation in MATLAB/Simulink of a wind generator with variable speed. The system considered is composed of a DC machine emulating the turbine, a permanent magnet synchronous machine making the base of the generator, in addition to a PWM power converter.

The robust iterative learning control is presented in this paper for the tracking control for linear systems with disturbances. An H infinity norm based on iterative learning control is used to analyze the system stability and to prove the convergence of the learning control rule. We proposed in this paper an initial robust control law applied to the plant then an iterative learning control is deduced which guaranteed the monotonic convergence of the system. The analysis and synthesis of this control law is based on the resolution of a convex optimization problem under constraints of LMI (Linear Matrix Inequalities).

With the rapid growth of industrial development and information technology, the electrical grid has recently witnessed deep transformations mainly in its infrastructure. It has moved from a centralized-control network depending on energy producers to a one that is distributed control with more consumers interaction. Therefore, the ancient grid has perceived a grid modernization making it a Smart grid. This new concept is characterized with its advanced architecture that is based on a two-way flow of electricity and communication and that involves components, including enhanced metering sensors, linked through a supervisory control and data acquisition system. The purpose of this paper is to provide a better understanding about the Smart grid concept, its potential advantages and its technologies including smart metering advancement and communication infrastructure. In addition, this paper exposes screens we designed of our application about the Supervisory Control and Data Acquisition of power distribution.

High voltage cables are permanently subjected to electrical and thermal operating constraints, leading to their progressive degradation and deterioration. The control and the identification of the thermal aging parameters of high voltage insulation require the use of several characterization techniques. In this work we have presented some results carried out from the use of different characterization techniques to study the mechanical and dielectric behaviors under thermal aging of cross-linked polyethylene (XLPE) used as insulation of high voltage cables. The evolution of XPE morphology under thermal aging was quantified with several physic-chemical characterization techniques such as FTIR, DSC and X-ray. The effect of thermal aging on the trapping and conduction mechanisms of XLPE under electron beam irradiation was also studied in the last part of this paper using SEM. The carried out thermal aging experiments consist to perform XLPE samples to elevate temperatures arranged from 80°C to 140°C until 5000h.

Writing is the language visual representation by a graphic signs system conventionally adopted by a community of people. The study of the handwriting process is an exploration of the properties of the biological system producing it and the main involved factors namely the nerve impulses generation, the pen displacement on a writing surface, etc. People with disabilities or suffering from various neurological diseases are facing so many difficulties resulting from problems located at the muscle stimuli or signals of the brain and which arise at the stage of writing. The handwriting velocity of a same writer or different writers varies according to different criteria: age, attitude, mood, writing surface, etc. Therefore, it is interesting to reconstruct an experimental basis records taking, as primary reference, the writing speed for different writers which would allow studying the global system during handwriting process. This paper deals with a new approach of the handwriting system modeling based on the velocity criterion through the exploitation of artificial neural networks and specifically the sigmoid neural networks as well as the Bayesian regularization principles.

This paper deals a correlation of ElectroMagnetic Interference (EMI) evolution with the switching performance of power RF LDMOS (Radio Frequency Lateral Diffused Metal-Oxide-Semiconductor) devices applied to a series chopper. In addition their influences on the dynamic parameters are studied after various accelerated ageing tests (thermal and electrical). The response of these parameters and the switching waveform are described. The findings of experimental results are presented and discussed. Measurements show that important variations are obtained on the devices rise time. After ageing tests, the charge trapping in the gate oxide causes the modifications in the Miller capacity level and width result in an increase of the rise time and decreased the fall time, consequently an increase of the switching slosses.
