Here we proposed a process to minimize the spectral distortion in IKONOS 1m color image. In this method the 1m multispectral (MS) fused image is processed from 4m MS and 1m panchromatic (PAN) image to which the relations of spectral response between PAN and each band of MS image are obtained most. To maintain this relation, four parameters are added with(More)
Various image fusion techniques have been conducted to merge various sensors data. However, when the existing image fusion processes are applied to the IKONOS images, the spectral distortion is appeared. To investigate this distortion problem, this work presents a study indicating that there are two reasons where the distortion of the spectrum is caused. To(More)
Wind power is a major source of renewable energy, and is in great demand around the world. However, wind power is difficult to manage due to large fluctuations in power output. To alleviate such fluctuations, this paper proposes a method for suppressing frequency deviation in wind power generation using storage battery systems that considers state of charge(More)
In Japan, the deviation in frequency caused by the increase in the amount of renewable energy introduced in power systems soon will become a major problem. Researchers use storage batteries for power systems to balance supply and demand. However, storage batteries are still inferior to pumped-storage plants in terms of cost and durability. In this paper, we(More)
For image fusion applications, the critical issue is how to produce a fused imagery with minimizing color distortion and maximizing the crease. However, due to nonsymmetrical spectral responses of IKONOS imagery, most existing techniques produce color distortion in 1m fused images. In our another report we have succeeded to reduce this color distortion(More)
Recent deregulation has increased the number of electricity transactions between areas. Tie-line available transfer capability (ATC) is an important index for such transactions. In longitudinal power systems such as those used in Japan, multi-swing is caused by the increase in tie-line power flows. This paper examines transient stability ATC, and proposes a(More)
Wind power is a major source of renewable energy and is in great demand around the world. However, wind power is difficult to manage owing to large fluctuations in the power output. To alleviate such fluctuations, this paper proposes a method for suppressing the frequency deviation in wind power generation using storage battery systems that consider the(More)
In Japan, frequency deviation under large-scale wind power penetration will soon become a major problem. To balance supply and demand, there is an idea of using storage batteries for power systems. However, storage batteries have disadvantage in terms of cost and durability compared with pumped-storage plants. This paper proposes a novel Load Frequency(More)
