In this paper, an energy storage system with voltage equalization strategy for wind energy conversion is presented. The proposed energy storage system provides a voltage equalization strategy for series-connected lead-acid batteries to increase their total storage capacity and lifecycle. In order to draw the maximum power from the wind energy, a perturbation-and-observation method and digital s...

A robust control algorithm is always needed to harvest maximum power from a Wind Energy Conversion System (WECS) by operating it consistently at Maximum Power Point (MPP) in the presence of wind speed variations. In this work, Tracking (MPPT) designed via Conventional Sliding Mode Control (CSMC), Super Twisting Algorithm (STA), and Real (RTA) applied Permanent Magnet Synchronous Generator (PMSG...

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...

An accurate forecasting method for power generation of the wind energy conversion system (WECS) is urgently needed under the relevant issues associated with the high penetration of wind power in the electricity system. This paper proposes a hybrid method that combines orthogonal least squares (OLS) algorithm and genetic algorithm (GA) to construct the radial basis function (RBF) neural network ...

Commercialization of wave energy will lead to the necessary deployment of Wave Energy Converters (WECs) in arrays, or wave farms. In order for projects in the United States to be approved, regulatory agencies must perform an Environmental Assessment proving little to no environmental impact. However, little is known about the environmental impacts of such wave farms. As a result, the environmen...

Space Vector Modulation (SVM) based Direct Torque Control (DTC) scheme is used for a variable –speed direct drive Permanent Magnet Synchronous Generator (PMSG) in a wind power generation system. SVM Provides more flexibility for inverter voltage utilization, in order to compensate the torque and flux errors in a smoother way than conventional DTC. SVM based DTC maintains constant switching freq...

Motivated by the increasing concerns over environmental challenges such as global warming and exhaustion of fossil-fuel reserves, renewable energy industry has become most sought-after source electrical production worldwide. In this context, wind conversion systems (WECS) are one dominant fastest-growing technologies, playing an increasingly vital role in power generation. To meet growing deman...
