Over the last few years, improving power extraction from wind energy conversion system (WECS) under varying speeds has become a complex task. The current study presents optimum maximum point tracking (MPPT) control approach integrated with neural network (NN)-based rotor speed and pitch angle to extract WECS. So, this reference model adaptive (RMAC) for direct-drive (DD) permanent magnet vernie...

Due to the intense penetration of wind energy into power grid, grid quality and stability have become a crucial necessity in this type generation. It is context that article has just designed an Adaptive Nonlinear Control strategy applied Permanent Magnet Synchronous Generator (PMSG) 1.5 MW power, order generate good cleanly usable energy. Interestingly, robust control algorithm mainly uses Lya...

Against the backdrop of increasing energy demands, the threat of climate change and dwindling fuel reserves, finding reliable, diverse, sustainable/renewable, affordable energy resources has become a priority for many countries. Marine energy conversion systems are at the forefront of providing such a resource. Most marine renewable energy conversion systems require tribological components to c...

The paper presents a comparative analysis on the steady-state behavior of two counter-rotating wind turbines with same components, where generator can operate as (with both mobile rotor and stator— Case ) vs. conventional fixed b electric machine. These energy conversion systems (WECSs) also have coaxial rotors one-degree-of-freedom (1-DOF) planetary speed increaser inputs one or outputs for co...

This paper focuses on improving the active and reactive power control of Wind Energy Conversion System (WECS) by employing the Battery Energy Storage System (BESS) and controlling the frequency and voltage regulation instantaneously. The proposed power control scheme is composed of two control loops so that they are implemented and designed for active power control and controlling the reactive ...

A discontinuous conduction mode (DCM) three-phase single-ended primary-inductor converter (SEPIC) is presented in this article. The analyzed operates as a high-power factor stage AC–DC conversion systems. As its main features, it presents three controlled switches and single control signal with simple implementation low-current harmonic distortion. topology, design equations, operation modes ar...

2. Warm core systems are equivalently barotropic because the thickness and mass fields align as vertically-stacked structures. The resulting lack of thickness advection by the geostrophic wind prevents any conversion of zonal available potential energy (PM) to eddy available potential energy (PE) by the geostrophic wind thus precluding any quasigeostrophic baroclinic instability for warm core s...

Green energy sources are implemented for the generation of power due to their substantial advantages. Wind is best among renewable options generation. Generally, wind system directly connected with network supplying power. In direct connection, there an issue managing quality (PQ) concerns such as voltage sag, swells, flickers, harmonics, etc. order enhance PQ in a conversion (WECS), peripheral...

Wind speed fluctuations and load demand variations represent the big challenges against wind energy conversion systems (WECS). Besides, inefficient measuring devices environmental impacts (e.g. temperature, humidity, noise signals) affect system equipment, leading to increased uncertainty issues. In addition, time delay due communication channels can make a gap between transmitted control signa...
