1. A power reception control method for a power storage element, the method comprising repeating a processing cycle to control element-receiving electric power received by the power storage element included in a load group in an electric power system for supplying electric energy to the load group including plural power storage elements via an electric power supply base point,
the processing cycle comprising:
acquiring information indicating differential electric power obtained by subtracting a current value of total transmitted electric power having been supplied to the entire load group via the electric power supply base point from a maximum value of the total transmitted electric power that is an available amount to be supplied to the entire load group via the electric power supply base point;
calculating a degree of priority of the power storage element indicating a level of priority regarding charging that the power storage element has over the other power storage elements in accordance with a numerical value indicating a demand of a user of the power storage element;
multiplying the differential electric power indicated in the acquired information by the degree of priority to calculate element differential electric power of the power storage element;
adding the element differential electric power to the element-receiving electric power in a previous processing cycle to update the element-receiving electric power; and
controlling the power storage element so as to receive the element-receiving electric power after being updated.
