Abstract

The disclosure is related to a method for controlling an electric power consumption amount of a consumer by a server coupled to a smart grid for managing electric power distribution. The method may include receiving signals having information on electric power consumption amounts from a meter of a consumer through a communication network, determining an electric power consumption pattern of the consumer based on the information on electric power consumption amounts, calculating electric power supply amounts for a predetermined time period based on the determined electric power consumption pattern of the consumer, and transmitting a control signal to the meter of the consumer through a communication network for controlling an electric power consumption amount of the consumer based on the calculated electric power supply amounts.
