Abstract

A method, device, and system for estimating impedance of a battery set associated with a battery energy storage system (BESS) are disclosed. The method may include, and the device or system, or both, may be configured for obtaining an AC signal that comprises an odd harmonic of an operating frequency of a system coupled with the BESS, injecting the AC signal into a node of the battery set, and estimating an AC impedance of the battery set based on a response of the battery set to the injected AC signal. The injected harmonic may be a third harmonic of a system coupled with the BESS, such as a utility system.
