In order to broaden the limited utilization range of wind power and improve the charging and discharging control performance of the storage battery in traditional small wind power generation systems, a wind power system based on a vertical-axis off-grid induction generator is proposed in this paper. The induction generator not only can run in a wide wind speed range but can also assist the vert...

A large amount of wind power has to be curtailed due to the inflexibility of the combined heat and power (CHP) system in the heating season in northern China. The power-to-gas (P2G) technology, which uses electricity to produce hydrogen or synthetic natural gas, has become a promising energy conversion option for the utilization of surplus power energy. In this paper, an integrated natural gas,...

39  Abstract— Utilization of wind power as renewable resources of energy has been growing rapidly around the world in the last decades. Wind power generation is fluctuating due to the variation of the wind speed. Therefore, the assessment of the output power of this type of generators is always associated with some amount of uncertainties. The output voltage and frequency from the ac generator...

Cover photo: The severity of global environment related issues is intensifying. Consequently, there is an urgent need for applications of natural energy such as wind power and solar energy, the utilization of hydrogen energy by using fuel cells or the like, the efficiency transport and supply of energy to areas of demand, non-wasteful utilization of energy that has been supplied, and other meas...

World wind power resources are abundant, but their utilization could be limited because wind fluctuates rather than providing steady power. We hypothesize that wind power output could be stabilized if wind generators were located in a meteorologically designed configuration and electrically connected. Based on 5 yr of wind data from 11 meteorological stations, distributed over a 2,500 km extent...

Wind energy one of the world’s fastest growing energy technologies. It is estimated that 16% of the world’s electricity will be harnessed from wind power by 2020. Efficient and stable utilization of wind energy has been an important problem. The present work is a comprehensive report on various topologies and generators used in WECS aimed at drawing comparison between the various options availa...

Nowadays, utilization of renewable energies for satisfying electricity demand has received more interest, and renewable electricity generation has been growing in the world. This study addresses the operational planning of a renewable electricity supply chain over a multi-period planning horizon. The purpose of this study is to maximize total profit and to optimize the operational decisions rel...

The paper describes a variable speed wind generation system where fuzzy logic principles are used for light load efficiency improvement and optimization. A squirrel cage induction generator feeds the power to an improved topology of matrix converter which pumps power to a utility grid or can supply to an autonomous system. The power factor at the interface with the grid is controlled by the mat...

In this master thesis, a model is proposed to enable profitable market participation of wind power plants considering the availability of second-party owned energy storage. A novel concept of storage capacity reservations is presented using which the wind power producer hedges against wind outcomes which are unfavourable with respect to its day-ahead market bids. The idea that wind power produc...
