This paper deals with the performance improvement of a variable speed wind turbine (VSWT) using a doubly fed induction generator (DFIG) based on a fractional order control. The decoupled direct control of active and reactive powers is used to achieve maximum power point tracking. The fractional order proportional and integral (FOPI) controllers are proposed to offer an additional degree of freedom compared to conventional ones. Controllers design is realized using an analytic method based on frequency domain specifications at crossover frequency namely phase margin, gain limitation and robust to gain variation. The obtained simulations results show the effectiveness and the performance control improvement of the considered wind energy conversion system in all the operating regions with objectives satisfaction of each region.

This study examines two cases at the same time. First, in order to increase both electromagnetic energy restraint and coupling efficiency, we propose a significantly smaller magnetic coupler design in space. Furthermore, compared to a standard flat-shaped ferrite core coupler and magnetic shield, this proposed system uses less ferrite. Second, the properties and spatial magnetic field distribution of magnetic couplers with shielding structures are investigated using CNIPR (International Commission on Non-Ionizing Radiation Protection) data. The suggested model is also modelled using the Ansys Maxwell finiteelement simulation tool, with the results displayed to demonstrate the efficacy and validity of the proposed design.

This paper proposes the control and energy management of a PV-Diesel-ESS micro-grid in islanded mode, where a two-level hierarchical control technique is adopted, the lower-level control to optimize/control the power from of the microgrid’s components, then comes the higher-level control to supervise the power flow and ensure its balance on the whole system while promoting self-consumption under a lowcost system. The proposed supervision algorithm manages the power flow according to the state of charge of the battery, which results in four modes of operation. To test the effectiveness of this supervisory algorithm, either to maintain the system frequency and voltage within their standard limits or to guarantee the continuity of power supply to the load and protect the energy storage system against over-charging /over-discharges, MATLAB simulation, for the whole system, is carried out for an exemplary day and under different critical scenarios and circumstances.

In order to select and generate optimal duty cycle for the maximum power point tracking (MPPT)in photovoltaic has been studied based on several techniques. In this paper, modified fuzzy logic controller (FLC) algorithm is proposed for better efficiency of a photovoltaic (PV) system connected to grid. The obtained results show that, the proposed fuzzy logic controller (FLC)is able track the maximum power in normal condition and abnormal conditions of solar radiation. Boost converter is used as an interface between the photovoltaic panels and the load. Then, the output voltage is converted to AC voltage via an inverter based on proportional-integral (PI) controller. the phase locked loop (PLL) is introduced for the synchronization and the LC filter is used to minimize the harmonics of output AC voltage. The obtained simulation results using Matlab/Simulink software show the effectiveness of the proposed control.

This study aims to determine the optimal configurations and topologies of an electrical distribution network. This problem is considered an optimization problem that requires criteria to be minimized while respecting various constraints. The objective function considered in the reconfiguration process is the energy not supplied (ENS) to the network. The minimization of this objective function can increase the reliability of network topologies, and the topology with the minimum ENS is the most reliable. The required objective function is expressed using a mathematical expression, which is used in the proposed optimization algorithms. First, this paper presents the objective function and constraints to be considered in the optimization problem. Then, to solve this problem, we use exhaustive research and the genetic algorithm (GA) for an IEEE1-33 bus distribution power system. Based on the obtained results, the optimization of various configurations using the GA contributed qualitatively to improving the reliability index, transited currents, power supply voltage, and execution time.

In this work, after behavior analysis of sliding mode controllers, we proposed an Adaptive fuzzy controller inspired by the sliding mode control. The controller uses two separate variables to estimate the surface and distance away from the setpoint. The progressive command is calculated based on a set of fuzzy rules that we developed. This surface is often a linear function of the successive regulation errors and the algebraic value of the parameter delta. This parameter is considered the first variable for surface estimation. The principle is to bring the current operating point by an adequate command towards this surface. To ensure the stability of the fault dynamics, the second part explains the principle of convergence from the operating point to the equilibrium point by using the distance variable. The AFLC controller with adaptive tuning is applied and capable of controlling complex non-linear systems in the presence of different perturbations. The simulation results under MATLAB / Simulink prove the improved performance of the proposed MPPT in terms of energy efficiency, reliability under different environmental conditions, and dynamic performance compared to conventional control.

In this study, an iron core shunt reactor with different numbers of air gaps was investigated and the most suitable design was tried to be obtained. First of all, detailed information was given about the shunt reactor and its types. The effect of the number of air gaps on the magnetic flux distribution was investigated in detail. With the help of the finite element method, it was aimed to obtain the most appropriate design by obtaining the desired value for the magnetic flux density by selecting the appropriate number of airgaps in the shunt reactor. The finite element results show that with the increase in the numbers of the airgaps, magnetic flux density decreases. However, considering the technical and economic aspects are also important.

In this study, an observer based on the theory of LPV systems is proposed to improve the performance of the fluxoriented vector control structure for the induction motor. Therefore, the dynamics of the motor are strongly influenced by the speed, stator and rotor resistances. This approach with polytopic modeling allows to take into account the parameters variation. The observer is also synthesized via an optimization of the L2 gain under linear matrix inequality constraint and Hinfinity standard problem synthesis. The simulation results prove both the quadratic stability and the robustness of the proposed approach.
