YiZhang, ...VladimirTerzija, inInternational Journal of Electrical Power & Energy Systems, 2022 5.3Frequency regulation and control The essence of thesystem frequencycontrol and frequency regulation (FR) is to adjust and control the output of the system to ensure the frequency deviation within the ...
A high load factor implies power utilization is moderately consistent. Low load factor demonstrates that at times an appeal is set. To benefit that pinnacle, capacity is sitting inactive for long times, in this manner imposing higher expenses on the system. Electrical rates are structured so clien...
Power factor of the size and the load on the circuit nature, such as incandescent bulbs and electric resistance furnace resistance load factor is 1, generally with electrical circuit power factor inductive load is less than 1. Power factor is an important technology in power system data. A co...

A new method of optimizing the Underfrequency load shedding (UFLS) has been developed in the paper. The main idea is that on the basis of the on-line measurement of the load frequency regulation factor, the load with smaller frequency regulation factor is cut off earlier than those with larg...
Participation factor used to address the interaction between the state variables and the modes in the power system. This property is used to choose weighting matrix of the state variables (Q). A linear, time, invariant mathematical model is derived for Iraqi National Super Grid System consisting ...
The performance of this method along with perfect harmonic cancellation (PHC) and unity power factor (UPF) strategies is evaluated on a distribution system model developed using PSCAD 4.2.1. The effect of selection of control strategy in damping the harmonic resonance, which is one of the main...
