| dc.description.abstract | This paper investigates a pricing model for an
electricity market with a hybrid congestion management method,
i.e. part of the system applies a nodal pricing scheme and the rest
applies a zonal pricing scheme. The model clears the zonal and
nodal pricing areas simultaneously. The nodal pricing area is
affected by the changes in the zonal pricing area since it is
directly connected to the zonal pricing area by commercial
trading. The model is tested on a 13-node power system. Within
the area that is applying nodal pricing, prices and surpluses given
by the hybrid pricing model match well with those given by the
full nodal pricing model. Part of the network is better utilized
compared to the solutions given by the full zonal pricing model.
However, the prices given by the hybrid system may send wrong
economic signals which triggers unnecessary generation from
existing capacities, exacerbates grid congestion, and induces
higher re-dispatching costs. | nb_NO |
