Considering limited ability of Proton Exchange Membrane Fuel Cell (PEMFC) systems to produce power, it is necessary to provide conditions, in which, the maximum power of the PEMFC can be achieved. The maximum power point tracker has an important role in increasing the efficiency of the PEMFC. One of its difficulties is rapid changes in operating conditions which affects on the maximum power point...
This paper presents a photovoltaic (PV) system with a maximum power point tracking (MPPT) facility. The goal of this work is to maximize power extraction from the photovoltaic generator (PVG). This goal is achieved using a sliding mode controller (SMC) that drives a boost converter connected between the PVG and the load. The system is modeled and tested under MATLAB/SIMULINK environment. In simulation,...
In this paper a PV system topology incorporating a new maximum power point tracking controller (MPPT) method using a PI controller is studied. The controller is formulated based on the bijectivity between the Voltage and Power in the PV generator (PVG) characteristic; therefore if the optimal voltage is reached, this means that the maximum of power is obtained. The proposed MPPT algorithm is implemented...
. This paper proposes an DC-linked hybrid diesel/photovoltaic (PV)/battery storage system for stand-alone applications. PV is the primary power sources of the system, a diesel engine is used as a backup and a battery as storage system. An overall power management strategy is designed for the proposed system to manage power flows among the different energy sources and the storage unit in the system...
In this paper, the authors present a controlled topology for a grid connected photovoltaic system (GCPS) including Static Var Compensators (SVC). The proposed system is consisted of a photovoltaic array, a boost converter, an inverter, a non linear load and a grid. The adaptation of the needed voltage required by the PWM controlled inverter is provided by a boost converter. The used inverter generates...
In this paper, the Authors present a hybrid photovoltaic-diesel system control. The considered system is composed of a self exited induction generator (SEIG), a photovoltaic array (PV array) and a fuzzy supervisor associated to an isolated DC load. The diesel motor is used to drive the SEIG in order to feed an isolated DC load through a diode rectifier, LC-LC filter and a DC bus when the PV array...
