The power mismatch between the generation and consumed power will result in frequency shift as well as a mismatch in reactive power [46]. The frequency shift is monitored to make sure if it is in the range of ± 3 %, whereas the reactive power mismatch will cause voltage variation and if the voltage varies beyond the pre-set values and is ...
