Advanced considerations in the implementation of Security-Constrained Optimal Power Flow (SCOPF) for electricity markets

Abstract

This paper describes how the SCOPF provides signals agents need to interact in electricity markets and some of the advanced features needed for its implementation. These include: sensitivity analysis, AC and DC options for both power flow and contingency analysis solutions, approximated limits including reactive power flows, unenforceable constraint management, modeling of load response as a control through curtailment contracts, determination of reactive power LMP's, modeling of nonlinear limits such as voltage stability and dynamic ATC through nomograms, variable area transfer pricing, and spatio-temporal analysis.
