1. A control system comprising:
a plurality of power balancing resources; and
a processor that controls each of the plurality of power balancing resources, wherein:
each power balancing resource includes a power storage device configured to be electrically connectable with an external electric power source;
the processor is configured to select one or more power balancing targets from among the plurality of power balancing resources, the power balancing targets to be included in a power balancing control that is performed using the external electric power source, and control each power balancing target of the one or more power balancing targets so as to cause the power storage device to charge or discharge for the power balancing;
the processor is configured to classify the power storage device as either a high capacity power storage device or a low capacity power storage device, the low capacity power storage device being a power storage device with a maximum capacity less than a maximum capacity of the high capacity power storage device; and
the processor is configured to
acquire information on a duration of the power balancing,
determine whether the duration of the power balancing is shorter than a threshold duration,
in a case where the duration of the power balancing is shorter than the threshold duration, execute a first power balancing control that causes the power balancing resource provided with the low capacity power storage device to charge or discharge for the power balancing, and
in a case where the duration of the power balancing is longer than the threshold duration, execute a second power balancing control that causes the power balancing resource provided with the high capacity power storage device to charge or discharge for the power balancing.
