Power system

This paper introduces a practical and simple power control method for wind energy conversion systems based on a doubly-fed induction generator. Due to the limitations of traditional proportional-integral controllers when the parameters of the doubly-fed induction generator and wind speed vary, fuzzy control theory is applied to overcome these challenges.

This paper investigates the system performance of hybrid time-power switching based relaying (TPSR) energy harvesting enabled in the multisource half-duplex relaying network over the Rayleigh fading channel. The outage probability (OP) of the proposed system model with implementing maximal ratio combining (MRC) and selection combination (SC) technique at the receiver is presented and analyzed.

Early detection of infertile and non-hatchable eggs benefits hatcheries by saving space, reducing costs, and preventing contamination from spoiled eggs. An automated system has been developed to detect and mark non-hatchable eggs efficiently. The system includes a conveyor that moves trays of 100 eggs through a high-power LED light assembly.

Solar energy, light and heat radiation from the Sun, has been exploited by humans since ancient times using a variety of technology development than ever before. Solar radiation along with secondary resources of energy like wind and solar energy, water power and biomass, make the most of renewable energy available on earth. Only a tiny fraction of the available solar energy is used.
