This paper presents a new hybrid wind turbine system that is formed by a continuously variable transmission connection of the turbine drive shaft with an air expander/compressor. A mechanical power split device is designed to synthesize the power delivered by the wind turbine and the air expander/compressor. A small-scale hybrid wind turbine system is mathematically modeled, analyzed, and validated...
Wind energy has been focused as an inexhaustible and abundant energy source for electrical power generation and its penetration level has increased dramatically worldwide in recent years. However, its intermittence nature is still a universally faced challenge. As a possible solution, energy storage technology hybrid with renewable power generation process is considered as one of options in recent...
The share of renewable energy utilization is growing fast in recent years, resulting in an increase in intermittence in power supply systems. Additionally, the demand profile will change drastically in the short and long term through increasing electrification of transport and heating, respectively. It is an important task to address the impact caused by the generation and demand uncertainties. In...
Energy Storage is evidently seen as a world-wide focusing research topic in recent years both for the industrial and academic sectors. This paper presents the recent research progress on a new hybrid system by integrating a wind turbine operation with compressed air energy storage. A scroll air motor is employed as the key device of “air-electricity power transformer” to convert compressed air energy...
Electrical power generation from wind energy has been recognized as one of major realistic energy sources in CO2 emission reduction worldwide. However, matching power generation with the load demand remains a great challenge, due to the nature of wind energy intermittency. The paper addresses this issue by developing a new system with the structure of a hybrid connection of the wind turbine and compressed...
