DISTRIBUTION SYSTEM STATUS ESTIMATING DEVICE |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a means for accurately estimating the actual amount of load in a section in which customers equipped with photovoltaic power generation devices by measuring the electricity generated by only some of the photovoltaic power generation devices, not by all the photovoltaic power generation devices. <P>SOLUTION: A distribution system status estimating device includes: a data collecting means for collecting the electric energy of each customer and the electricity generated by the photovoltaic power generation device thereof; electricity generated correlation model data that provides the relation of the electricity generated by each photovoltaic power generation device; and an amount of electricity photovoltaically generated estimating means for estimating the amounts of electricity generated by the other photovoltaic power generation devices using the above electricity generated correlation model data and the electricity generated by the photovoltaic power generation device. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
