GRID INTERCONNECTION DEVICE, GRID INTERCONNECTION SYSTEM AND POWER CONTROL SYSTEM
First Claim
1. A grid interconnection device connected to a power distribution system through which alternating-current power is transmitted and to a power supply device provided to a customer, the grid interconnection device comprising:
- a detector configured to detect a start of transmission of the alternating-current power based on a state of the alternating-current power;
a receiver configured to receive a grid interconnection start instruction for starting grid interconnection between the power distribution system and the power supply device, through a predetermined transmission path; and
a controller configured to control grid interconnection and power system separate of the power distribution system and the power supply device, whereinthe controller starts grid interconnection between the power distribution system and the power supply device upon receipt of the grid interconnection start instruction in a state where the detector detects the start of transmission of the alternating-current power.
