| Summary: | In Malaysia, the electricity tariff is based on the active energy consumed and does
not include any reactive (energy) power required. In order to recover the extra cost
incurred in supplying the reactive power required by the consumers, the utility
imposes a surcharge on a consumers whose power factor averaged over a month is
below the value of 0.85pf. However, the surcharge is imposed on medium to large
commercial and industrial consumers only. This paper proposes a new method for
valuation of Reactive Power in power system. This method uses two important
factors to determine the most important Reactive Power source power system. These
two factors are: Voltage Sensitivities and Voltage Adequacy and Stability (PV
Curve). In this paper AHP method has been used to classify the Reactive power
sources according to their importance in power system. The effectiveness of the
proposed method is verified under IEEE 9-bus system. |
