In power system, load frequency control has been primary issue. Our main objective is to maintain the equilibrium between generated power and load demand without deviation in frequency and tie-line power flow. This paper deals with differential evolution (DE) algorithm based optimizing technique to obtain the optimal value of gains of proportional-integral and proportional-integral-derivative controller...
In recent years the amount of data stored in educational database is growing rapidly. The stored database contains hidden information which if used aids improvement of student's performance and behaviour. In this paper predictive modelling approach is used for extracting this hidden information. Data is collected, a predictive model is formulated, predictions are made, and the model is validated as...
Harmonic contamination and low power factor in power systems caused by power converters have been a great concern. The effect of harmonics in current due to lagging power factor are the increase in current flow in the capacitors which results in additional heating of the capacitors and reduce its life, increased magnitudes of neutral currents in three phase systems, over-heating in transformers and...
