Abstract
The charging and discharging control apparatus includes an acquisition unit that acquires at least one of a direction and magnitude of electric power flowing between an AC power line and power system, and a control unit that controls charging of the power storage apparatus based on a change in at least one of the direction and magnitude of electric power flowing between the AC power line and power system when a charging amount to the power storage apparatus is increased by a predetermined amount.
Claims21
A charging and discharging control apparatus that controls charging and discharging of a power storage apparatus,
- the power storage apparatus being connected to an AC power line, and
- the AC power line being connected to a power system, being connected to a DC power generation apparatus through a DC/AC conversion apparatus, and being connectable to a load,
- the charging and discharging control apparatus comprising:
- an acquisition unit that acquires at least one of a direction and magnitude of electric power flowing between the AC power line and the power system;
- and
- a control unit that controls charging of the power storage apparatus based on a change in at least one of the direction and magnitude of electric power flowing between the AC power line and the power system when a charging amount to the power storage apparatus is increased by a predetermined amount.
A control method performed by a charging and discharging control apparatus that controls charging and discharging of a power storage apparatus, the power storage apparatus being connected to an AC power line, and the AC power line being connected to a power system, being connected to a DC power generation apparatus through a DC/AC conversion apparatus, and being connectable to a load, the control method performed by the charging and discharging control apparatus comprising:
- acquiring at least one of a direction and magnitude of electric power flowing between the AC power line and the power system;
- and
- controlling charging of the power storage apparatus based on a change in at least one of the direction and magnitude of electric power flowing between the AC power line and the power system when a charging amount to the power storage apparatus is increased by a predetermined amount.
A program of a computer for implementing a charging and discharging control apparatus that controls charging and discharging of a power storage apparatus,
- the power storage apparatus being connected to an AC power line, and
- the AC power line being connected to a power system, being connected to a DC power generation apparatus through a DC/AC conversion apparatus, and being connectable to a load,
- the program causing the computer to execute:
- a procedure of acquiring at least one of a direction and magnitude of electric power flowing between the AC power line and the power system;
- and
- a procedure of controlling charging of the power storage apparatus based on a change in at least one of the direction and magnitude of electric power flowing between the AC power line and the power system when a charging amount to the power storage apparatus is increased by a predetermined amount.
