Abstract
A control apparatus comprising: a voltage acquisition unit that acquires a voltage of a DC bus connecting a power conditioner and a storage battery unit; an output power limiting unit that sets to zero an output power limit of PCS output power which is power output to the load side by the power conditioner when the voltage exceeds an upper limit threshold value or when the voltage falls below a lower limit threshold value; and a limited power release unit that gradually increases or gradually decreases the output power limit after the output power limit is set to zero.
Claims8
A control device comprising:
- a voltage acquisition unit that acquires a voltage of a DC bus connecting a power conditioning system (PCS) and a storage battery unit;
- an output power limiting unit that sets an output power limit of PCS output electric power which is electric power output to a load side by the power conditioning system to zero when the voltage exceeds an upper limit threshold value or when the voltage falls below a lower limit threshold value;
- and
- a limited power release unit that gradually increases or gradually decreases the output power limit after the output power limit is set to zero.
A control method comprising:
- a step of acquiring a voltage of a DC bus connecting a power conditioning system (PCS) and a storage battery unit;
- a step of setting an output power limit of PCS output electric power which is electric power output to a load side by the power conditioning system to zero when the voltage exceeds an upper limit threshold value or when the voltage falls below a lower limit threshold value;
- and
- a step of gradually increasing or gradually decreasing the output power limit after the output power limit is set to zero.
A program that causes a control device to execute:
- a step of acquiring a voltage of a DC bus connecting a power conditioning system (PCS) and a storage battery unit,
- a step of setting an output power limit of PCS output electric power which is electric power output to a load side by the power conditioning system to zero when the voltage exceeds an upper limit threshold value or when the voltage falls below a lower limit threshold value, and
- a step of gradually increasing or gradually decreasing the output power limit after the output power limit is set to zero.
