1. A computer that manages a plurality of resources each capable of acting as a reserve of an external power source, wherein:
each of the plurality of resources includes an electricity storage device;
the computer is configured to execute:
resource classification of classifying each of the plurality of resources as a first resource or a second resource having higher rated charging power than the first resource; and
resource selection of selecting, for a reserve request, resources to act as the reserve from among the plurality of resources;
wherein the computer is configured to:
determine a target reserve for the reserve request;
select resources to act as reserves for the reserve request in the resource selection such that a total of rated charging power of the selected resources reaches the target reserve;
select resources corresponding to the first resource with priority over resources corresponding to the second resource in the resource selection for a first reserve request, and to select resources corresponding to the second resource with priority over resources corresponding to the first resource in the resource selection for a second reserve request, wherein an adjustment period of the second reserve request is longer than an adjustment period of the first reserve request;
trade reserves in an electricity market and generate the reserve request when the computer has made a successful bid for a reserve in the electricity market, wherein in the electricity market, reserves are traded on a time block basis;
in the resource selection for selecting resources to act as the reserve corresponding to the successful bid, a reserve request of a predetermined number of time blocks or a number of time blocks smaller than the predetermined number corresponds to the first reserve request and a reserve request exceeding the predetermined number of time blocks corresponds to the second reserve request;
select resources from the first resources in the resource selection for the first reserve request such that a total of rated charging power of the selected resources approaches the target reserve, and when all resources corresponding to the first resource are selected and yet a total of rated charging power of the selected resources does not reach the target reserve, select resources enough to cover a shortage from the second resources; and
select resources from the second resources in the resource selection for the second reserve request such that a total of rated charging power of the selected resources approaches the target reserve, and when all resources corresponding to the second resource are selected and yet a total of rated charging power of the selected resources does not reach the target reserve, to select resources enough to cover a shortage from the first resources.
