A Cost Allocation and Pricing Method for Reactive Power Service in the New Deregulated Electricity Market Environment

It is necessary to restructure the reactive power pricing framework. The exchange of real energy is the dominant intention of the electric power exchange and the reactive power has its inherent limitation, but the importance and stimulation effect of a effective reactive power cost structure is important also, especially to the performance of the power market, the quality of electric power exchange and the security of the power system. All this tell us that reactive power should be treated as more than a subsidiary factor

HVDC and FACTS

Many electrical utilities around the world have purchased an RTDS Simulator to connect to replica controls for HVDC and FACTS projects. A slightly simplified copy of the controls are delivered to site along with an RTDS Simulator to represent the power system. These “replica Simulators” are then interfaced with the controls and are used to investigate proposed network changes and control modifications, to test scheme upgrades and refurbishment, and to train utility personnel.

Fundamentals and Applications of Power Transfer Allocation Using Graph Theory in Systems with Loop Flow

In this paper, a novel elimination circulating flow method is suggested, an alternative reactive power pricing method in systems with circulating flow has been proposed, and a comparison between bus-mixed average method and loop-breaking method is displayed
