Title:
POWER SYSTEM STATUS ESTIMATION DEVICE AND STATUS ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/110082
Kind Code:
A1
Abstract:
Provided is a power system status estimation device capable of increasing the likelihood that status estimation calculations converge. Thus, a power system status estimation device 1 is equipped with: a measured value selection unit 102 for selecting a prescribed combination of measured values using which it is predicted that the power system status estimation calculations will converge, from among the measured values from each sensor provided in the power system; and a status estimation calculation unit 101 for estimating the status of the power system on the basis of the prescribed combination of measured values selected by the measured value selection unit and the system model for the power system.
