CONTROL DEVICE, CONVERSION DEVICE, CONTROL METHOD, AND ELECTRICITY DISTRIBUTION SYSTEM

摘要

In a control device configured to control power to be supplied to a specific load from at least one of a converter that has a power generator and a storage battery, and a commercial power supply, the control device determines whether the commercial power supply is in a power failure state or a power distribution state, in which: when determining that the commercial power supply is in a power distribution state, the control device causes both of the converter and the commercial power supply to be connected to the specific load; and when determining that the commercial power supply has made a transition from a power distribution state to a power failure state, the control device causes the commercial power supply to be disconnected from the specific load while maintaining the connection between the converter and the specific load.

1. A control device that controls power to be supplied to a specific load from at least one of a converter that has a power generator and a storage battery both connected thereto and converts DC power into AC power, and a commercial power supply, wherein
the control device determines whether the commercial power supply is in a power failure state or a power distribution state, and wherein: when determining that the commercial power supply is in a power distribution state, the control device causes both of the converter and the commercial power supply to be connected to the specific load; when determining that the commercial power supply has made a transition from a power distribution state to a power failure state, the control device causes the commercial power supply to be disconnected from the specific load while maintaining connection between the converter and the specific load; and when determining that the commercial power supply has made a transition from a power failure state to a power distribution state, the control device causes the converter to be disconnected from the specific load and the commercial power supply to be connected to the specific load.
