Abstract

Various methods of determining local prices for access to power on electricity grids have been proposed since deregulation became widespread. The aim of power regulatory authorities is to ensure fairness by restrictions on collusion. Nodal pricing is used in various transmission networks around the world but has a flaw in the opportunity it offers suppliers to exploit the nexus between historical topology in transmission networks and inevitable line load limits.
