Abstract
The purpose of this research is to establish the stand-alone power generation system by means of wind power generation in ports and coastal area. It is necessary to know the variance characteristics of demand of electric power in port facilities. This paper shows investigated data of electric power usage in a port that is located at the west coast of Hokkaido. The deferences of demand and supply by wind generation and hybrid system with solar generation are analyzed and the contermesures to reduce the energy gap of demand and supply also discussed.
