Reactive power tracing and pricing for practical utility system

Abstract EN

This paper presents the intuition of power flow tracing techniques to determine amount of reactive power delivered by the regulating devices.

The reactive power loss allocated to the users of the transmission line is evaluated.

The reactive power flow including the effect of power components like capacitors, shunt admittance power sources towards the reactive power is compared with three different reactive power evaluation methods namely Equivalent reactive compensation (ERC)method, Modified Ybus method and Virtual power flow approach method by taking WSCC9 bus system and Indian Utility 62 bus system.

Reactive power pricing to find opportunity cost of generators and capacitors were validated using IEEE bus system as test system.
