Assessment of Voltage Fluctuations for Battery Storage Systems Providing Frequency Response Services

This paper investigates voltage fluctuations caused by the operation of battery energy storage (BES) units which provide frequency response (FR) and fast (FFR) services using a test network based on typical part United Kingdom (UK) mainland system. provides an overview current FR/FFR currently used in UK, summary their modes operation. Using DIgSILENT Powerfactory, introduces simple disturbance generator to mimic disturbances that would occur UK network, then subsequently uses representative distribution show how associated with BES can develop across electrical network. The contribution knowledge creating systematic approach for assessing flicker concerns island networks, control algorithm novel generator.
