Method for estimating load by energy meter including load estimation model based on neural network and energy meter using the same

An energy meter for estimating one or more loads, wherein the energy meter includes a load estimation model based on a neural network, comprising:

• at least one memory that stores instructions;
• and
• at least one processor configured to execute the instructions to perform or support another device to perform processes of:
• (I) sequentially generating multiple pieces of sampled supply electric power information by sampling information on electric power, supplied to a customer through one or more input lines of a distribution board, based on a predetermined sampling rate, (II) sequentially inputting the multiple pieces of the sampled supply electric power information to the load estimation model and instructing the load estimation model to output load information which is a result of distinguishing each of the loads, being operated by the customer at a t-th time, wherein t is an integer bigger than or equal to 2, based on (t−k)-th sampled supply electric power information to t-th sampled supply electric power information, wherein k is an integer bigger than or equal to 1 and less than t, respectively corresponding to a (t−k)-th time to the t-th time, among the multiple pieces of the sampled supply electric power information, and (III) (i) transmitting the load information and information on an amount of the electric energy to a data management server, wherein the information on the amount of the electric energy is acquired by integrating the electric power supplied to the customer during a time period including a specific period between the (t−k)-th time and the t-th time through the input lines, and (ii) instructing the data management server to monitor at least part of the information on the amount of the electric energy consumed by the customer, information on each sub-electric power for each of the loads, and information on each sub-amount of the electric energy for each of the loads,
• wherein the transmitted load information is used by the customer or a provider of the electric power supplied to the customer to control use or management of the electric energy.
