In this paper, the control scheme of a wind energy conversion system for remote sites using fuzzy logic is presented. Two fuzzy controllers are proposed: the first one is dedicated to the maximum power point tracking (MPPT) of a variable speed permanent magnet synchronous generator wind turbine. The second fuzzy controller has the the objective to manage(More)
These last years, the use of wind energy has increased considerably. In this paper, the model of the wind electrical conversion system (WECS) is developed. The considered WECS is composed of an induction generator connected to the wind turbine. The goal of this paper is to control the power generated by the WECS to the grid. We propose a new control(More)
In this paper we propose the study of a centrifugal pump control system driven by a three-phase induction motor, which is supplied by a PhotoVoltaic PV generator. The system includes solar panel, a DC / DC converter equipped with its MPPT control, a voltage inverter to three-phase Pulse Width Modulation PWM and a centrifugal pump driven by a three phase(More)
In this paper, a simulation model of a solar cell is defined to allow estimation of the electrical behavior of the cell with respect changes on environmental parameter of temperature and irradiance. Maximum Power Point Trackers (MPPT) play an important role in photovoltaic (PV) power systems because they maximize the power output from a PV system for a(More)
This paper deals with the modeling of a centrifugal pump system driven by a three-phase induction motor, which is powered by a photovoltaic generator. The system includes solar panel, a DC / DC converter equipped with its MPPT control, a the three-phase PWM (Pulse Width Modulation) voltage inverter and a centrifugal pump driven by a three phase induction(More)
In this paper, we develop the overall model of the wind energy conversion systems (WECS) structure based on induction generator (IG). The goal of this paper is to control the power generated by the WECS and transmitted to the grid. We propose a new control strategy based on Neuro-fuzzy technique in order to control the power of the WECS. The main drawback(More)
