Abstract
A power management system includes a photovoltaic power generator connected to a power network, an energy storage device configured to be connected to the power network, and a server. The server is configured to: acquire a predicted value of solar radiation at a prediction time at a point where the photovoltaic power generator is installed; calculate a predicted value of power generated by the photovoltaic power generator at the prediction time by using the predicted value of solar radiation; set a target range of an SOC of the energy storage device by using the predicted value, and control the SOC in such a way that the SOC falls within the target range by the prediction time; and set the target range to a wider range when reliability of the predicted value is low than when the reliability of the predicted value is high.
