Problems solved by technology

[0004] However, in wind power generation, solar power generation, and other power generation methods that depend on the weather, even if the weather is suitable for power generation and a lot of power is generated, the power may not be effectively used and discarded, which is uneconomical.
[0005] In addition, there is a problem that although electric power companies install various power plants to meet the maximum needs of power consumption, when the functions of some power plants such as nuclear power plants are stopped due to disasters such as earthquakes, the Electricity is needed to supply electricity, and it is forced to reduce the frequency of trams, suspend operations, cut power, etc., reduce the production of enterprises, cause traffic obstacles, etc., and disrupt the economy

Embodiment 1

[0024] (1) An electric power company having a power station buys back electric power at 21 yen / 1 kWh when the power usage fee is 20 yen / 1 kWh, for example, from the owner of the electric vehicle.

[0025] (2a) The owner of the electric vehicle, when selling the electricity stored in the battery to the power company without using the electric vehicle, specifies the remaining amount (kWh or percentage %) that should remain in the battery to sell the electricity stored in the battery electricity.

[0026] (2b) The owner of the electric vehicle specifies the day of the week (Saturday, etc.), date and time (22:00 to 24:00, etc.) and Specify the remaining amount (kWh or percentage %) that should be left in the battery to sell the power stored in the battery.

[0027] (3) The electric power company recovers electric power from the battery of the electric vehicle as needed, and supplies the recovered electric power to places that require electric power.

Abstract

The present invention provides a power managing system which can effectively store the generated power and recover the stored power for use according to demand. The power managing system includes a power plant and a plurality of electric vehicles each having a battery for storing the power generated by the power plant. The power stored in the battery of each electric vehicle is recovered to the power plant according to demand for power during the time when each electric vehicle is not in use.

Description

technical field [0001] The present invention relates to a power management method capable of efficiently utilizing power. Background technique [0002] Power companies such as Tokyo Electric Power generate electricity through various power stations such as hydroelectric power stations, thermal power stations, nuclear power stations, wind power stations, and solar power stations. Consumption in enterprises, general households, etc. [0003] Since power consumption varies depending on time of day, season, etc., electric power companies use various power generation methods to supply power according to demand. Since it is difficult to accumulate the electricity generated first, it is necessary to manage the operation of the power plant according to the change of demand. Since the operation of the air conditioner requires a huge amount of electricity in summer, the maximum power supply is adjusted and managed according to the maximum power demand in summer. Operation of various...
