Optimal under frequency load shedding using CUCKOO search wirh levy flight algorith for frequency stability improvement.
(2015)
Frequency stability in a power system is very important as it determines the synchronous speed of electrical machines. Therefore it should remain within acceptable limits even when the system is disturbed. In order to ...
Adaptive Neuro - fuzzy Inference system based control of three - phase hybrid power filter for harmonic mitigation
(nternational Journal of Emerging Technology and Advanced Engineering, 2015-11-25)
This paper presents a three-phase hybrid powerfilter based on artificial intelligence control approach. It consists of C- type passive filter in parallel with a shunt active filter that is controlled by an adaptive Neuro-Fuzzy ...
