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.

This paper presents comparative study for power system transient stability improvement using Static Var Compensator (SVC) and Thyristor Control Breaking Resistor (TCBR). To show the effectiveness of the dynamic oscillation, relative rotor angles criterion is used for power system transient stability assessment. The proposed method is tested on the WSCC3 nine-bus system in the case of three-phase short circuit fault in one transmission line. Simulation results and comparative study comparison are presented in this paper.

In the era of sustainable development, photovoltaic (PV) technology has shown significant potential as a renewable energy source. Photovoltaic generators (GPV) have a non-linear current-voltage characteristic, with a maximum power point (MPP) characterized by an optimal voltage, and depends on environmental factors such as temperature and irradiation. To extract each time the maximum power available at the terminals of the GPV and transfer it to the load, an adaptation stage is used, consisting of a Boost chopper controlled by a maximum power point tracking technique (MPPT) through a stage of pulse width modulation (PWM). Our choice has focused on two techniques which are: the Incremental Conductance Method (InCond) and that of control using the fuzzy logic. The implementation and simulation of the system (photovoltaic generator, chopper Boost, PWM and MPPT techniques) are then performed in the Matlab/Simulink environment.

In order to ensure the continuity and the quality of electrical energy distribution, the diagnostic of polluted insulators is of utmost importance. For this purpose, a new performance monitoring methodology is proposed in this paper. Once acquisition of the applied voltage and the leakage current signals is carried out on a plan insulator model under uniform and non-uniform pollutions, the continuous (CWT) and discrete (DWT) wavelet transforms are performed. In case of a uniform pollution, the CWT with its time-scale analysis allows to characterize the state of the insulator surface by detecting the apparition of electrical discharges from the applied voltage waveform. While for a non-uniform pollution configuration, the DWT through its multi-resolution analysis allows us to predict the occurrence of the partial arcs phenomenon on the insulator surface based on the leakage current waveform. Through this work, the effectiveness of the wavelet technique has been highlighted as a new tool for the diagnostic and monitoring of polluted insulators performance.

This paper studies a water and energy management strategy dedicated to an autonomous water desalination system fed by a hybrid (Photovoltaic (PV) and Wind) power generator without battery storage. RO technology is one of the most powerful processes used for desalination to provide fresh water. Accordingly, renewable energy can be used especially by means of hybrid (PV-wind) system. Taking into consideration the multidisciplinary and strongly coupled device from a systemic point of view, the system being considered as a whole. Inside this framework, the water/energy management of the global process has to be optimized in order to produce fresh water while considering the different system constraints with the given intermittent power.

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.
