Abstract: The present disclosure relates to a multifunctional energy storage system in which one energy storage system is capable of performing a plurality of functions and an operating method thereof. According to an aspect of the present disclosure, there is provided a multifunctional energy storage system including: a battery; a power converter to transfer power between a system and the battery; a multi-function controller to select the activation functions, to generate an integrated objective function, a weight, and a constraint condition corresponding to the activation functions, and to generate a control value for controlling each function included in the activation functions on the basis of the integrated objective function, the weight, and the constraint condition; and an individual function controller to receive the control value for each of the activation functions from the multi-function controller and to control the power converter so that each function is performed on the basis of the received control value.

Abstract: An embodiment of the present disclosure provides an arc detection method, in which an apparatus detects arcs, comprising the steps of: obtaining time series data for measured values of an electric current flowing in a wire; calculating first statistical values indicating dispersion degrees with time of the measured values or dispersion degrees with time of variances of the measured values from the time series data; and determining that an arc occurs in the wire or that the possibility of arc occurrence in the wire is high in a case when at least one of the first statistical values is out of a predefined range.
