The system for demand power and power charges simulation, and its implementation method

PURPOSE: A contract power and a power charge calculating simulation system and implementation method thereof are provided to simulate exact forecast electric charge by directly inputting electric appliance which user uses the same themselves or was going to use the same to a web program. CONSTITUTION: A first DB(110) stores electric device use information of client which is authenticated. A second DB(120) stores a kind of instrument of electric device model, electric device name, power consumption, and capacity. A server(100) receives information of the first DB and the second DB. The server predicts electric charge simulation by calculation contract power of the client.
