1. A power generation planning apparatus comprising:
a communication device in communication over a network with a plurality of power generators of a power system;
a memory storing at least one program; and
a processor in communication with the memory and the communication device, the processor, when executing the at least one program, configured by the at least one program to perform operations including:
determining an output range of at least one power generator of the plurality of power generators that satisfies a plurality of operational constraints;
determining a power generator output of the at least one power generator in a single time section based on the output range determined for the at least one power generator;
when an operational constraint violation occurs in the power generator output in the single time section, determining a target output for the at least one power generator in the single time section; and
to eliminate the operational constraint violation, correcting the output ranges and the power generator outputs in the single time section and previous time sections so that the power generator output of the at least one power generator in the single time section becomes the target output.
