<P>PROBLEM TO BE SOLVED: To estimate power demand accurately and carefully. <P>SOLUTION: Power demand is estimated, making use of the two pieces of information referring to the regional distribution of weather forecast information such as temperature, humidity and the regional characteristics of the power demand. More specifically, an estimation model maker 13 makes a local weather forecast model tinged with observation data by a weather radar, a ground rain gauge, etc., based on GPV data delivered from the Japan Meterological Agency or an overseas agency, and makes more detailed and accurate weather forecast data. A statistical analyzer 14 puts the regional characteristics of power demand into a database in advance, based on the past actual results. Then in forecasting processing, this system obtains the power demand corresponding to a forecast temperature and humidity separately for each region, referring to the actual results data base, and finally obtains the quantity of power demand in the whole region. In this case, this can also make the weather conditions and power demand correspond to each other by each region by a return system or the like, coupled with information about a rain quantity, wind direction, wind speed, etc. <P>COPYRIGHT: (C)2003,JPO |
