RISReduction of Tripping Caused by Inrush Current in the Black-Start Units Using Reduced Voltage Level Start-up
In a widespread blackout, system
restoration must begin from pre-selected
generating units with the ability to start
themselves. Units, which participate in this
ancillary service, must have the ability to...
A novel approach for evaluating market power in reactive power markets
for identifying and detecting dominant and must-run suppliers are required. Market power problems are more intricate in reactive power markets than those in other markets due to the specific properties of this ancillary service. This paper introduces a new...
The impacts of capabilities and constraints of generating units on simultaneous scheduling of energy and primary reserve
Abstract Frequency control, as an ancillary service, is usually provided by generation reserves. Modern generating units have special technical capabilities; e.g., their governor operation mode can be selected to be either active or passive...
Participation in Reactive Power Market Considering Generator Aging
– As one of the most important ancillary services, reactive power production plays a
crucial rule in power system operation, reliability and security. Because of the opportunity costs
in providing reactive power, producers are under...
