6 FAQs about [Reactive power compensation capacitor capacity reduction]

Does reactive power compensation reduce total power loss in radial distribution systems?

In this paper, reactive power compensation in radial distribution systems has been investigated in reducing total power loss. On the contrary to other previous studies, the study has used local compensation at each load for increasing power factor to 0.9 and then capacitors in distribution lines have been placed as other studies.

Why is capacitive shunt compensation important?

Use of capacitive (shunt compensation) on various part of the power system improves power factor, Reduce power losses, improves voltage regulation and increased utilization of equipment. Reference: Electric power generation, Transmission and distribution by Leonard L.Grigsby. Power system supply or consumes both active and reactive power.

How does reactive power compensation work?

In the first stage, reactive power compensation at each load in the systems is implemented for increasing the power factor into 0.9. In the second stage, metaheuristic methods are employed to determine the location and size of additional capacitors at nodes in distribution lines.

What is the total reactive power compensated in the system?

The total reactive power compensated in the system is, respectively, 1193, 1192, 1040, 1054, 1024, and 1080 kVAr by two-step method, WCPSO, LSFACA, PSO, PPA, and TSA. The comparison indicates that the compensation capacity is not the same for all methods and even for three applied methods.
