The proliferation of Renewable Energy Resources (DER's) into Direct Current (DC) microgrids, growing rapidly, have attracted great consideration of the researchers providing numerous challenges, compared to AC microgrids. With the coupling technology for DER”s., the main benefit of power electronics is the capability to provide effective control in order to deal with voltage variations related to renewable sources intermittency and load disturbances. In this paper, a non-linear method based on sliding mode control (SMC) is implemented in order to control the bidirectional converter of the storage system component and ensure the stable operation of the MG. In fact, voltage regulation and system stability are crucial tasks in order to ensure the stable operation of islanded DC microgrid. The effectiveness and robustness pertaining to the proposed controller compared to proportional integral (PI) controller are validated through MATLAB/Simulink simulation under sudden variations of power sources and load. Lastly, results show superiority and demonstrate that the proposed method has a good performance in reducing and eliminating voltage oscillations and voltage ripples that jeopardize the system stability. Bus voltage stabilizing and power quality enhancement are realized and achieved.

In this work, the dynamic model of DFIG with rotor short circuit fault is suggested. In this model, an H_infinity observer based flaw estimation and analysis scheme is developed. In order to assure the stability system, a fault compensator of a winding short circuit flaw is established and combined with the conventional system controller. Finally, the simulation results of the rotor short circuit effects and the proposed approach performance are developed and represented using Matlab/Simulink.

We propose in this work a new algorithm of optimization named Crow Search Algorithm CSA to elicit neuro-fuzzy model such TS type. In the proposed study, a particle is formed by two tasks: its structure and its parameters. The CSA algorithm was compared with others: GA and PSO through a modeling of nonlinear system. The results prove that CSA method gives optimal mean of MSE and optimal of standard deviation of MSE compared to GA and PSO.

With the growing awareness of greenhouse gas emissions and their consequences along with the ever increasing electric energy demand, researchers and policy makers are looking forward for renewable energy sources. Consequently, microgrids with different kinds of energy sources have taken a leap over a past decade, making pathways for integration of hybrid microgrids with the existing power systems. However, a critical study of practical problems in planning a microgrid is necessary prior to its commissioning, to maintain satisfactory level of availability with reduced cost of energy being produced. In this connection, this paper investigates various analytic and soft computing techniques that address the single objective as well as multi-objective optimization problems encountered in optimal planning of hybrid microgrid. Further, to quantify the merits and demerits of the considered methods, a case of grid connected hybrid microgrid powered by PV, wind and battery sources is studied and the conclusions are reported.

This paper presents a self-securing decentralized on-chip network interface (NI) architecture to Multicore System-on-Chip (McSoC) platforms. To protect intra-chip communication within McSoC, security framework proposal resides in initiator and target NIs. A comparison between block cipher and lightweight cryptographic algorithms is then given, so we can figure out the most suitable cipher for network-on-chip (NoC) architectures. AES and LED security algorithms was a subject of this comparison. The designs are developed in Xilinx ISE 14.7 tool using VHDL language.

This paper develops a modern control strategy in order to command an AC/DC converter. This technique is a combination between Direct Power Control and Fuzzy Logic (FL-DPC). First of all, the first phase consists in mathematical modeling of the proposed converter using Kirchhoff's equations. Subsequently, the second part is devoted to the description of the main blocks constituting the fuzzy controller. Thereafter, he developed the inputs of the fuzzy controller as well as its output. In a concrete way, the author specified as inputs; the sector and the two errors of the active and reactive powers. However, the control vector is designated as an output. Therefore, with a view to accomplish good performances like; a sinusoidal waveform of current, a small rate of THD, an almost unitary power factor and a reliable adjustment of the DC bus voltage, the author resorted to the Matlab/Simulink environment. Finally, the bidirectional power flow is checked based on the simulation of three scenarios; inverter mode, rectifier mode and shut-down mode.

This paper concerns the identification of a trans-esterification reactor using PWARX (PieceWise AutoRegressive eXogenous) hybrid systems. The OBE (Outer Bounding Ellipsoid) algorithm is then applied in order to estimate the parameters for each sub-system. This algorithm is used for system identification when bounded disturbances are present. This paper aims to experimentally apply the OBE algorithm to represent the dynamic of a transesterification reactor with PWARX system using real measurements.

The present work proposes a rectifying circuit called rectenna. We propose an optical rectenna based of solar cell antenna operating at 3.5 GHz for the future 5th generation. This hybrid system solar cell antenna allows energy recovery (DC signal) as well as RF signal for Data Transmission. On the other hand, we have proposed a conversion circuit RF/DC for the unitile RF part. A parametric study has been shown that the efficiency can reach 66.2%.
