A power calculation apparatus calculates an amount of power suppliable and demandable between a battery and a power grid. The power calculation apparatus includes a microprocessor and a memory connected to the microprocessor. The microprocessor is configured to perform: predicting the amount of power suppliable and demandable between the battery and the power grid at a predetermined point in time to calculate a prediction value of the amount of power suppliable and demandable; and switching a calculation logic to be applied to a calculation of the prediction value, based on a length of duration from a present point in time to the predetermined point in time.

Power calculation apparatus and power calculation method

A power calculation apparatus predicting and calculating an amount of power suppliable from a vehicle having a battery to a power grid via a connection apparatus, the power calculation apparatus includes a microprocessor and a memory connected to the microprocessor. The microprocessor is configured to perform: predicting a position of the vehicle after a predetermined duration; predicting a degree of likelihood of connection of the vehicle to the connection apparatus after the predetermined duration, based on a predicted position of the vehicle after the predetermined duration and the connection apparatus; and predicting the amount of power suppliable from the vehicle to the power grid after the predetermined duration, based on the degree of likelihood.

A power calculation apparatus includes a microprocessor and a memory. The microprocessor is configured to perform: acquiring a power amount information regarding amounts of power input to and output from a plurality of vehicles, the amounts of power being detected by a plurality of measuring instruments provided in the plurality of vehicles or interposed between a power grid and the plurality of vehicles; classifying the plurality of measuring instruments based on errors possessed by the plurality of measuring instruments to set a plurality of groups; and calculating a total power input and output in each of the groups, based on the power amount information. The setting the plurality of groups includes setting the plurality of groups such that a mean value of errors of amounts of power in the groups is a predetermined value or less.

A power calculation apparatus calculating an amount of power suppliable to a power system by an energy source connectable, at a connection point, to the power system and capable of power generation and power storing, the power calculation apparatus includes: a microprocessor and a memory connected to the microprocessor, wherein the microprocessor is configured to perform: specifying a position of the connection point of the energy source in connection with the power system; acquiring a capacity information indicating a power generation capacity or a remaining storage capacity of the energy source; and calculating an amount of power suppliable by the energy source to the power system in an area within a predetermined range including the connection point, based on the capacity information and the position of the connection point.
