1. An electric power agreement system that evaluates a flow plan for an electric power line,
the electric power line including at least one line facility,
at least one customer connected to the at least one line facility,
the electric power agreement system comprising:
a processor to execute a program; and
a memory to store the program which, when executed by the processor, causes the processor to
calculate an agreement result including an amount of electric power to be traded and an electric power unit price for the at least one customer;
calculate a total of actual numbers of an amount of surplus electric power for the at least one customer connected to the at least one line facility as a flow achievement for the at least one line facility individually;
calculate a total value of the amounts of electric power to be traded in the agreement result corresponding to the at least one customer connected to the at least one line facility as the flow plan for the at least one line facility individually;
calculate a variation of the flow achievement from the flow plan assumed in the future as a risk for the at least one line facility individually on the basis of a variation of the flow achievement from the flow plan in the past;
determine for the at least one line facility individually whether a risk-considered flow plan obtained by adding the risk to the flow plan fulfills line constraint defined on the at least one line facility; and
execute the agreement result with the at least one customer according to the flow plan that fulfills the line constraint,
wherein the processor recalculates the agreement result corresponding to the at least one customer connected to a deviating line facility by changing the electric power unit price until the processor determines that the risk-considered flow plan for the deviating line facility fulfills the line constraint, the deviating line facility being a line facility for which the risk-considered flow plan is determined not to fulfill the line constraint.
