Fixed costs of providing ancillary services from power plants: Reactive supply and voltage control, regulation and frequency response, operating reserve--spinning. Final report
- Encotech, Inc., Schenectady, NY (United States)
This report describes methodologies to determine the fixed costs for a steam cycle generating unit to participate in Reactive Supply and Voltage Control (RS-VC), Regulation and Frequency Response (RFR), and Operating Reserve-Spinning (ORS) services. It is intended for use by a Generator of electricity who is planning to offer these ancillary services in a competitive market. The methodology is based on common steam power plant engineering and economic principles. Reactive supply and voltage control provides reactive supply through changes to generator reactive output to maintain acceptable transmission system voltages and facilitate electricity transfers and provides the ability to continually adjust transmission system voltage in response to system changes. Regulation and frequency response service include all rapid load changes whether their purpose is to meet the instantaneous load demand, to balance control area supply resources with load, or to maintain frequency. Spinning reserve is provided by generating units that are on-line and loaded at less than maximum output. They are available to serve load immediately in an unexpected contingency such as an unplanned outage of a generating unit.
