This paper presents a combination system of wind energy conversion and hydrogen production. Hydrogen is expected as an alternative energy source in the future, and this is the best way to produce it from renewable energy like wind energy. On the other hand, the output of a wind generator, in general, fluctuates greatly due to wind speed variations, and thus the output fluctuations can have a serious...
As wind turbine output is proportional to the cubic of wind speed, the wind turbine generator output fluctuates due to wind speed variations. Hence, if the power capacity of wind power generators becomes large, wind power generator output can have an influence on the power system frequency. Since Superconducting Magnetic Energy Storage (SMES) system has the ability to provide both active and reactive...
This paper proposes a system composed of a wind turbine generator system and energy storage system (ESS) unit, in which ESS is controlled for smoothing the wind generator output power. A determination of power rating of ESS unit which is sufficient for the smoothing control but as small as possible is very important problem. In this paper, an evaluation method for the determination of the power rating...
Due to the recent expansion of renewable energy applications, wind energy conversion is receiving much interest all over the world. However, output fluctuations of wind generators cause network frequency variations in power systems. This can decrease the power quality and then cause a restriction of wind farm installation, especially in an isolated power system, for example, power system in a small...
For the recent expansion of renewable energy applications, wind energy conversion is receiving much interest all over the world. However, output fluctuations of wind generators cause network frequency variation in power system. This can decrease power quality and then cause a restriction of wind farm installation, especially in a small power system. Therefore this problem needs to be solved for further...
Recently, the use of wind energy conversion system (WECS) is increasing all over the world. Wind generators with several mega-watt rating have been developed and installed in wind farms, therefore, the influence of WECS on power system is becoming greater. Particularly a frequency variation of power system is a significant problem. This will damage to power quality, and cause a restriction of wind...
