Transmission Switching in Joint Energy and Spinning Reserve Markets Considering Stability Criteria
International Journal on Electrical Engineering and Informatics
There is a great resolution calling for smart grids in recent years. Introduction of new technologies, that make the network flexible and controllable, is a main part of smart grid concept and a key factor to its success. Transmission network as a part of system network has drawn less attention. Transmission switching as a transmission service can release us from load shedding and remove the constraints' violations. In addition to removing the congestion and decreasing the system cost,
... stem cost, transmission switching may damage generating units due to transient states in instance of reconfiguration. Therefore, in optimal transmission switching, the system security, practical limitations and possible damages should be considered. In this paper transmission switching is modeled in probabilistic energy and spinning reserve day-ahead market clearing problem to guaranty the network security standards. The results show that proposed transmission switching in addition to significant decrease in system cost, can improve the other network characteristics such as system reliability.
