POWER SYSTEM MONITORING DEVICE AND POWER SYSTEM MONITORING METHOD

Title:

POWER SYSTEM MONITORING DEVICE AND POWER SYSTEM MONITORING METHOD

Document Type and Number:

WIPO Patent Application WO/2016/063660

Kind Code:

A1

Abstract:

In the present invention, a determination is made as to whether the adjustment power in a specific fluctuation cycle is deficient even if the correlation between a fluctuation cycle and a demand fluctuation range changes. A power system monitoring device is provided with: a communication unit that receives measurement data which has been measured in a power system; a storage unit that stores the measurement data, stores configuration data representing the configuration of the power system, and stores adjustment power representing the ability to adjust output according to the components of a specific cycle among power fluctuations within a preset designated area within the power system; and a calculation unit that, on the basis of the measurement data and the configuration data, calculates demand data which is time sequence data for demand within the designated area, calculates a plurality of fluctuation amounts which respectively indicate the size of a plurality of cycle components in the demand data, calculates the correlation between a plurality of cycles and the plurality of fluctuation amounts, calculates the fluctuation amount of a specific cycle on the basis of the correlation, and compares the fluctuation amount of the specific cycle and the size of the adjustment power of the specific cycle.
