In this paper a new bidirectional DC-DC converter is proposed to transfer energy between ultra-capacitor and DC bus in electric vehicle. The work presents the average model of this converter. The last model is used to calculate the small signal and transient characteristics of the converter. The derived small signal model can be developed by the transfer… (More)

This paper presents a new sliding mode Switching Table direct power control for three-phase grid-connected voltage source converters (VSC). The proposed Direct Power Control (DPC) strategy employs a nonlinear sliding mode (SM) approach to directly calculate the required converter's control voltage so as to eliminate the instantaneous errors of active and… (More)

This paper deals with the modeling and control of a Wind Energy Conversion System (WECS) based on a Permanent Magnet Synchronous Generator (PMSG). The WECS operate at variable speed and the control algorithm is based on Direct Power Control (DPC) with an AC/DC conversion system with a PI controller for the DC bus output. The laboratory test system is… (More)

This paper describes the continuation power flow method used in studies of voltage stability limits. In this work we were improve that the point of voltage limit will changes with loading parameter. However, we used this method in order to analyses voltage collapse. It is based on a predictor-corrector algorithm. We applied this method to an example of nine… (More)

This paper deals with the analysis and simulation of a Tunisian Wind farms in Sidi-Daoud, the most important wind farm in Tunisia. In this farm constant speed wind turbines are used. The first section devoted to the presentation of the wind farm of Sidi-Doud. In the second part, we present the aerodynamic model of the wind turbine and the transient model of… (More)

This paper presents a review of two Maximum Power Point Tracking (MPPT) methods used in order to extracting maximum possible power from the wind energy conversion systems based on doubly fed induction generator. These two methods are namely tip speed ratio (TSR) control and hill-climb search (HCS) control. The control of the doubly-fed induction generator… (More)

The long-lived waste transmutation system is analysed with the grid of the actual technological applicability. Specific questions in reactor, accelerator, interface between them and radioprotection difficulties are formulated for clarify the complexity of a burning waste system. Some remarks are based on the results of two OECD Benchmarks (simulation of… (More)

Several converter configurations have been proposed in literature to achieve fuel-cell power conversion systems. In this paper a new converter high frequency unidirectional DC-DC was proposed simulated and realized. This last one allows to obtain an output voltage is 550V from an input voltage of 28V (output voltage of fuel-cell). The control strategy used… (More)

This paper deals with the bifurcation and dynamic stability structure in a dynamic power system model using the Matcont software package. We present a detailed investigation of several bifurcation phenomena, so the continuation, using one parameter (reactive power) from equilibrium computed by time integration, leads to limit point, Hopf bifurcation, Period… (More)

This paper proposes a Direct Active and Reactive Power Regulation of Grid-Connected converters using Sliding Mode Control approach applied to three phase PWM converters. The DPC-SMC controller regulates the DC-link voltage, active and reactive power-flows of the grid-connected converter. The proposed DPC-SMC strategy scheme calculates directly the required… (More)
