TLDR
In this article, an analysis of real-time pricing policies of reactive power using a modification of the OPF (optimal power flow) model is presented, followed by a case study illustrating the magnitudes and ranges that realtime prices might take on under different circumstances.Abstract:
An analysis is made of real-time pricing policies of reactive power using a modification of the OPF (optimal power flow) model. The theory of real-time pricing of reactive power is presented, followed by a case study illustrating the magnitudes and ranges that real-time prices of reactive power might take on under different circumstances. The efficiency implications of real-time pricing of reactive power are compared with traditional power factor penalties. It is concluded that real-time pricing of reactive power should develop simultaneously with that of active power for maximum economic efficiency and smooth operation of the electricity marketplace. >read more

Cost analysis of reactive power support
J.W. Lamont,J. Fu +1 more
TL;DR: In this article, a cost-based reactive power dispatch methodology is presented, which minimizes the total cost of reactive power support and determines the resultant reactive profile, and this cost is further expanded to include the pricing of reactive powers.

Decomposition model and interior point methods for optimal spot pricing of electricity in deregulation environments
TL;DR: In this article, an integrated optimal spot pricing model is presented, which includes the detailed derivation of optimal nodal specific real-time prices for active and reactive powers, and the method to decompose them into different components corresponding to generation, loss, and many selected ancillary services such as spinning reserve, voltage control and security control.

Fast Contingency Evaluation Using Concentric Relaxation
TL;DR: A fast method for evaluating contingencies either in real time in an actual emergency or for security monitoring is introduced, which begins with treating the system or a piece of it as electrically rigid and gradually relaxing the results tier by tier to account for the actual flexibility of the transmission.
