Assessment of the Norwegian Transmission Pricing Rules by Using a Modified AC-OPF

Abstract: This paper focuses on the combined effects of loss factors
and zonal pricing in a system that takes as a starting point the procedures
of transmission pricing in the Norwegian power system. It interprets the
notion of loss factors in an AC power flow model, and develops a method for
finding zonal prices consistent with a restricted AC optimal power flow.
The effects of decomposing the nodal prices to find a loss factor to cover
the marginal cost of losses, and letting the congestion management be
resolved by zonal prices based on a DC approximation of the flows, are
evaluated by comparing the resulting net prices to those of an optimal AC
power flow (ACOPF).
