This study suggests a model to include a solar power system or photovoltaic system (PV) in the control of frequency by taking into account a percentage of the PV power production for back-up reserve.This is done by investigating two scenarios: PV contribution in (1) initial primary frequency control and (2) entire primary frequency control.As expla
here During a routine analysis of whistlers on the wide-band VLF recording of the DEMETER satellite, a specific signal structure of numerous fractional-hop whistlers, termed the "Spiky Whistler" (SpW) was identified.These signals appear to be composed of a conventional whistler combined by the compound mode-patterns of guided wave propagation, sugg
