Abstract
The voltage and reactive power monitoring/control method includes: measurement data for the power system and data for the system equipment of the power system are used to calculate the system status for the power system at the time of measurement; data for a status estimation calculation result and predicted data for the power generation and load of the power system are used to predictively calculate a system status at a future time from the time of the power system measurement; a fluctuation component is obtained for the predicted value of the data obtained from the power system; the reactive power required to suppress the fluctuation component is obtained, as a required reactive power amount; a reactive power distribution subject is selected from a plurality of pieces of control subject equipment; an output distribution calculation is performed for the required reactive power amount for the selected control subject equipment.
