"Quantifying the impact of supply frequency adjustments for DER control" by Sean Elphick, Duane A. Robinson et al.
An unexpected challenge facing network operators due to high penetration levels of small-scale solar photovoltaic occurs when diesel backup generators are used to maintain supply to small network islands during maintenance. Most grid-connected small-scale solar inverters in Australia have no means of grid control and it is uneconomical to individually isolate each device within premises. Taking advantage of out of frequency protection settings of the inverters to disable output of distributed generation is one potential mechanism Network Service Providers are considering when operating the die...
