Abstract
In order to maintain a system frequency within a permissible range under limitations of the output of a power source to be controlled, a calculation device pertaining to a load-frequency-controlling device of the present invention: predicts time-series data indicating the status of individual power sources in a future control period, the prediction being carried out on the basis of system model data, system data, and renewable energy data; calculates, on the basis of power source data, and for each of the power sources, at least any one of a deviation state indicating the degree to which the time-series data deviates from the limitations and/or a surplus state indicating the degree to which the time-series data shows a surplus with respect to the limitations; resolves the deviation state; and calculates the amount of adjustment in the output of each of the power sources, on the basis of the deviation state and the surplus state, under the condition that the total output of the power sources is maintained.
