Reactive Power and Voltage Control in Deregulated Environment [PDF]
2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005 Reactive power support and voltage control is a key type of ancillary services in the deregulated electrical power market. A review of some important issues of reactive power support, including cost analysis, reactive power pricing, valuation, is presented in this paper. An optimal power flow (OPF) is used based on real time pricing theory.
