Abstract
There is disclosed a method of precisely controlling a discharge capacity of a sodium-sulfur battery in an interconnection system where a power generation device in which an output fluctuates is combined with a power storage compensation device including a plurality of sodium-sulfur batteries. The sodium-sulfur battery in which a discharge capacity control value is to be corrected or reset is specified among the plurality of sodium-sulfur batteries, the discharge capacity control value of the specified sodium-sulfur battery is corrected, and all of the plurality of sodium-sulfur batteries is successively specified to repeatedly correct or reset the discharge capacity control value.
Claims8
A control method of a plurality of sodium-sulfur batteries, comprising:
- providing an interconnection system where a power generation device in which the output fluctuates is combined with a power storage compensation device to supply an electric power to a power system, the plurality of sodium-sulfur batteries comprising the power storage compensation device and compensating a fluctuation of an output of the power generation device,
- specifying the sodium-sulfur battery in which a discharge capacity control value is to be corrected or reset, among the plurality of sodium-sulfur batteries;
- correcting or resetting the discharge capacity control value of the specified sodium-sulfur battery;
- and
- successively specifying all of the plurality of sodium-sulfur batteries to repeatedly correct or reset the discharge capacity control value.
