Abstract
A distributed energy resources control apparatus for controlling power from a distributed energy resource in a system section separable from a power system includes a detecting unit, a receiving unit, and a control unit. The detecting unit detects a fault of the power system. The receiving unit receives a signal indicating authorization for the distributed energy resource to perform independent operation as linking with the system section, when the system section is separated from the power system. The control unit controls a power converter converting power from the distributed energy resource and outputting to the system section, based on measurement results of a voltage and a frequency of the system section, when the fault is detected and the signal is received.
