Performance-Aware Control of Modular Batteries for Fast Frequency Response

IEEE Transactions on Sustainable Energy
Modular batteries can be aggregated to deliver frequency regulation services for power grids. Although utilizing the idle capacity of battery modules is financially attractive, it remains challenging to consider the heterogeneous module-level characteristics such as dynamic operational efficiencies and battery degradation.

A Submodule With Integrated Supercapacitors for HVDC-MMC Providing Fast Frequency Response

IEEE Transactions on Power Delivery, 2022
Modular multilevel converters (MMCs) have been recognized as the most attractive technology for high voltage direct current (HVDC) applications during the last years. Their advantages include the ability to freely control the internally stored energy in the distributed submodules (SMs) and to independently control AC and DC power. Recent studies showed

A Study of Frequency Specificity of the Auditory Fast Responses

AUDIOLOGY JAPAN, 1976
In order to establish the application of action potentials (AP) of the cochlear nerve and brain stem auditory evoked response (BSR) in clinical audiology, the frequency specificity of them was studied using the special masking techniques.The change of AP and BSR latencies and amplitudes of white noise evoked responses were observed using the high and ...
