Electric power information generation device and electric power information display system

An electric power information generation device comprising:

• a storage device configured to store data regarding an electric power demand;
• and
• a processor configured to calculate, on a basis of the data stored in the storage device and a demand response request, an electric power demand in absence of the demand response request and an electric power demand in accordance with the demand response request,
• the storage device storing instantaneous electric energy data of each of purchased electric energy, sold electric energy, electric energy generated by a power generation device, electric energy charged to a storage battery, and electric energy discharged from the storage battery,
• the processor further configured to generate screen display information for a display device to display a third screen showing a state of electric power supply and demand between a power generation device, a power system grid, a storage battery, and an electrical appliance at a prescribed time in accordance with the demand response request,
• in the third screen, the state of electric power supply and demand being shown by a symbol indicative of the power generation device, a symbol indicative of the power system grid, a symbol indicative of the storage battery, a symbol indicative of the electrical appliance, and a symbol indicative of a direction of a supply flow of electric power.

An electric power information generation device comprising:

• a storage device configured to store data regarding an electric power demand;
• a processor configured to calculate, on a basis of the data stored in the storage device and a demand response request, an electric power demand in absence of the demand response request and an electric power demand in accordance with the demand response request and
• a list storage unit for storing a list of at least one electric appliance which is controllable in response to the demand response request, and power consumption of the at least one electric appliance,
• the processor further configured to generate, on a basis of the power consumption obtained from the list, screen display information for a display device to display a sixth screen showing a list of the electrical appliance which can be used within a range of electric power allowed to use.

An electric power information display system comprising:

• an electric power information generation device comprising:
• a first screen generation unit configured to generate screen display information for displaying a first screen showing:
• a predicted change with time in an electric power demand in a prescribed period in absence of a demand response request;
• and a change with time in an electric power demand in a demand response request period in accordance with a demand response request;
• and
• a third screen generation unit configured to generate screen display information for displaying a plurality of third screen showing a state of electric power supply and demand between a power generation device, a power system grid, a storage battery, and at least one electrical appliance at a prescribed time in accordance with a demand response reques;t and
• a display device configured to display a screen based on the screen display information generated by the electric power information generation device,
• wherein each of the plurality of third screens showing different states of the electric power supply and demand,
• wherein the display device displays the plurality of third screens in a selectable manner and feeds a control device configured to control the power generation device, the storage battery, and the at least one electrical appliance with a control content corresponding to a selected one of the plurality of third screens.
