The dc series and series-parallel wind farms have been recently proposed as alternatives to ac for offshore applications. A dc wind turbine for use in dc series and series-parallel wind farms has been proposed in this paper. The operation of the dc series and series-par...

For the purpose of providing cheap, affordable and reliable electrical energy to communities in need and power-up new industries and enterprises, a small onshore wind farm with an estimated capacity of 500 kW is designed and studied. With the help of a wind rose, wind r...

The economic viability of tidal energy projects will likely require large-scale deployment, with tens, or even hundreds, of turbines positioned in an array. There is limited published research available on the viability of large-scale deployments, which will depend on b...

An efficient solar cooker has been designed, developed and tested. The device can be used for cooking, boiling and roasting of different foods in clear days. The important part of this new device is its stationary mode and maximum capture of energy through improved desi...

This paper proposes a control strategy to maximize the wind energy captured in a variable speed wind turbine, with an internal induction generator, at low to medium wind speeds. The proposed strategy controls the tip-speed ratio, via the rotor angular speed, to an optim...

This paper proposes an alternative robust observer-based linear control technique to maximize energy capture in a 4.8MW horizontal-axis variable-speed wind turbine. The proposed strategy uses a generalized proportional integral (GPI) observer to reconstruct the aerodyna...
