Supply-demand balance controller

摘要

A first predicting unit predicts a power demand required by each customer. A first reliability value calculator calculates the reliability value of the predictive power demand for each customer. Predicted power supply from a power system is calculated with respect to each power generating unit. A second reliability value calculator calculates the reliability value of the predictive power supply for each power generating unit. A balancing unit obtains a supply-demand margin level based on the difference between: a first weighted sum obtained by performing weighted sum on the predictive power demand and a weight depending on the reliability value; and a second weighted sum obtained by performing weighted sum on the predictive power supply and a weight depending on the reliability value. A plan creator creates a plan for controlling power used by the controllable appliance of the customer based on the supply-demand margin level.
