Abstract
To provide a secondary battery controlling apparatus and a controlling method that can keep a storage amount of a secondary battery used for supply and demand control of a power system not close to 100% or 0%. The present invention is a power supply and demand controlling apparatus of a small-scaled power systemincluding distributed power suppliesincluding a secondary battery and a controlling method, wherein the secondary battery controlling apparatus includes a power generation planning partcalculating a planned output value of the distributed power supply based on a past load power and output data including track record data of a power generation output, a planned storage amount estimating partestimating a planned storage amount of the secondary battery from the planned output value of the secondary battery calculated at the power generation planning part, an actual output detecting partmeasuring and detecting an actual output value of the secondary battery, an actual storage amount estimating partestimating an actual storage amount from the actual output value of the secondary battery detected at the actual output detecting part, and a storage amount controlling partcontrolling the actual storage amount back to the planned storage amount if there is a difference between the planned storage amount estimated at the planned storage amount estimating part and the actual storage amount estimated at the actual storage amount estimating part.
