Mathematical Modeling and Evaluation of Performance Characteristics of a Hybrid Solar PV and Wind Energy System

Journal of Applied Science and Engineering, 2022
Solar Photovoltaic (SPV) and wind energy are two major sources of renewable energy that are intermittent in nature. A hybrid system consisting of SPV and Wind Energy Conversion System (WECS) can meet the energy needs as either of the sources continues to

On Reducing the Shaft Torque Ripple of Small-to-Medium-Scale Wind Energy Conversion Systems Using Multi-Pulse Autotransformer Rectifier

Energies, 2018
In a small-to-medium-scale wind energy conversion system (WECS), diode rectifiers rather than pulse-width modulated (PWM) rectifiers are widely adopted due to the features of high reliability and low cost.

Using time‐series remote sensing to identify and track individual bird nests at large scales

Remote Sensing in Ecology and Conservation, EarlyView.
Time‐series airborne imagery can potentially track individuals over time to collect information beyond one‐off counts. Using weekly UAS‐based imagery of wading bird colonies, we develop an automated approach to identifying nests. Our algorithmic approach detected 68–74% of known nests and exhibited similar performance to human review of imagery ...

Sensorless double integral sliding mode MPPT control for the WECS

, 2018
In this paper, a double integrator sliding mode controller (DISMC) via the mechanical sensorless maximum power point tracking (MPPT) method is suggested to extract maximum power from a wind energy conversion system (WECS).
