Electric power visualization method and electric power visualization device

摘要

A house uses solar light generated electric power and external commercial electric power and consumes the electric power with a household electronics load or the like. The house includes an electricity storage device and an electric power management device. The electric power management device further has a function to calculate transition of the load electric power, transition of the solar battery generated electric power, and transition of a leveled external commercial electric power during one day, classify the electric power by the power generation methods, apply a green index serving as a standardized index which is defined in advance to each power generation method to calculate an electric power green index, and display a result thereof on a display unit.

主权项

1. An electric power visualization method for visualizing content of electric power for input-side electric power or load-side electric power in an electric power management system which receives electric power generated by a plurality of power generation methods as the input-side electric power and supplies to a load as the load-side electric power based on the input-side electric power, the method comprising:
a display step in which the input-side electric power or the load-side electric power is classified into generated electric power of each of the power generation methods and is displayed with different display methods for each classification of the power generation method, wherein the electric power management system sets electric power stored in an electricity storage device which is charged based on the input-side electric power as a storage battery electric power, and supplies to the load as the load-side electric power based on the input-side electric power and the storage battery electric power, and wherein in the display step, the storage battery electric power is classified into the generated electric power of each power generation method based on data of one of best mixing models, and is displayed with different display forms for each classification of the power generation method.
