The design of a hybrid solar/wind/Biomass electrical energy supply system is presented. Power requirements for a typical Algerian isolated village and the sizing of the electrical circuit are described. Some simulation results on PV solar panels and wind turbines behavior for different temperatures and wind speeds respectively are also given. A power flow(More)
This paper considers pitch control using a fuzzy logic and dc bus electrical power control in variable speed wind turbines. The system is equipped with a PMSG (Permanent Magnet Synchronous Generator) connected to the grid through back to back power converter. Variable speed wind turbines have the capability to deliver more power than the fixed speed ones,(More)
In this paper an intelligent power distribution system for an isolated village supplied with renewable energies is proposed. The system different components are described. The control and management algorithms have been implemented in a PIC microcontroller. The measurement and control unit has been realized. Measurements and tests have been carried out at(More)
In this paper the optimum hybrid wind diesel electricity supply system for an Algerian remote village is determined. Since the windiest region of the country is situated in the south west the study has been carried for a particular site located in that area. First Algeria's wind map is presented followed by a detailed sizing of a wind diesel hybrid system(More)
In this paper a power control and load management strategy for an isolated hybrid energy system is proposed. The presented solution can deal with all situations especially when the lack amount of supply power is less than 30% of maximum power of the Diesel Generator. The whole system has been simulated using SIMULINK software. An added value of the work is(More)
The objective of this study is the design of a photovoltaic pumping station for a remote site in the valley of LAGHOUT region located in the high plateaus of Algeria. First the site water needs and the availability of solar energy have been defined. Then the PV generator has been modeled and simulated. The water pump and the other system components have(More)
Voltage regulation at point of common coupling (PCC) using a doubly fed induction generator (DFIG) based wind energy conversion system (WECS) is achieved through reactive power control. WECS produces reactive power when the voltage is less than grid nominal voltage and it consumes it in the opposite case. In this paper a method to achieve this goal is(More)
Solar energy reaching a given surface depends directly on sun's orientation and sensor's position. Concentrated solar power systems are using sun-tracking heliostats to reflect maximum solar heat to a thermal receiver mounted atop a central power tower. The focused heat boils water within the thermal receiver and produces steam to supply a turbine for power(More)
How to collect the maximum of solar energy with the best installation of a photovoltaic module by predicting the sun position is presented in this contribution. The objective is to optimize the tilt of a photovoltaic module according to the sun position from the sunrise to sunset with an aim to maximize the efficiency. The trajectory of the sun is estimated(More)
