1. A power converter for being connected to a transmission line, the power converter comprising:
an input unit configured to be electrically connected to a device that is able to input electric power from the transmission line and/or output electric power to the transmission line;
a voltage change unit connected to the input unit and configured to change voltage;
a voltage adjustment unit connected to the voltage change unit and configured to adjust the voltage supplied to the transmission line;
a target setting unit configured to set a first target value of the voltage change unit;
a voltage monitoring unit connected to the transmission line and configured to observe the voltage of the transmission line; and
a threshold determination mechanism connected to the voltage monitoring unit and configured to calculate a second target value of the voltage adjustment unit in accordance with voltage of the transmission line, wherein
the target setting unit of the power converter is configured to generate the first target value as an output target of the voltage change unit in accordance with the voltage observed by the voltage monitoring unit, and
the first target value has characteristics to change a threshold voltage for controlling output of the voltage adjustment unit depending on time.
