1. A control apparatus configured to control a plurality of distributed power supplies connected to an electric power system, the control apparatus comprising:
a first calculation unit that comprises a processor to calculate in advance reactive electric power to be output by each of the distributed power supplies in an event of a fault on the electric power system; and
a command output unit that comprises the processor to output, to each of the distributed power supplies, a command signal for causing each of the distributed power supplies to output the reactive electric power calculated in advance by the first calculation unit when it is detected that the fault has occurred on the electric power system;
wherein the reactive electric power calculated in advance is selected from a solution for a type of the fault from solutions to optimal power flow problems calculated in advance, at a fixed cycle.
