This paper presents the performances of an artificial intelligent fuzzy logic controller (FLC) based maximum power point tracking (MPPT) and a conventional perturb observe (P&O) MPPT is presented for stand-alone PV system tested in emulated test bench experimentation. The studied composed DC supply emulating panel, DC/DC boost converter, variable resistive load real-time implemented dSP...

In this paper, a systematical controller design method for a two-stage grid-connected photovoltaic power conditioning system (PCS) is proposed. For a pre-stage boost converter to achieve the stable operation in the entire region of solar arrays (SAs), the digital resistive current (DRC) mode controller is proposed. This algorithm is very simple to implement with a digital controller and there i...

<span lang="EN-US">The operating performance of a PV module/array is extremely reliant on the weather (temperature/irradiation) and non-linear. Thus, to ensure that array produces maximum possible power at any time regardless external conditions, point tracking (MPPT) techniques are required. The solution suggested in this paper involves taking into account two cascaded controllers as fol...

In modern time the demand of electric energy widely increases day by day due to the reduction of the fossil fuels like (gases, liquids, coals, oil etc.) and the other environmental issues the all of world is looking for the alternative. The solar energy is the most renewable and sustainable energy sources. This paper present Simscape based modeling and performance of the photovoltaic generator ...

This paper proposes a small wind energy conversion system comprises permanent magnet synchronous generator (PMSG), uncontrolled rectifier, conventional H-Bridge inverter and dc-dc bi-directional converter. The dc link capacitor is connected to a storage system through Bi-directional power flow link. A hybrid pulse width modulation (HPWM) controller is used to regulate the ac load voltage and fr...

Design and implementation of constant frequency sliding mode current control for grid connected Photovoltaic (PV) inverter is presented along with Maximum Power Point Tracking (MPPT). Proposed constant frequency sliding mode control retains the advantages of good dynamic response as in hysteresis control, better reference tracking capability and robustness like predictive control. Proposed curr...

This paper deals with a control scheme to extract maximum power from the wind energy conversion system (WECS) using Maximum Power Point Tracking Algorithm (MPPT) from a Doubly Fed Induction Generator (DFIG). In order to ensure the continuous supply of power, battery backup is established. The control scheme for standalone system includes the charge controller circuit for battery bank and pitch ...

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 both the production and the storage of e...
