The results of the economic analysis are reported in Table 5 and Table 6. The cost of electricity purchased from the network and that BD 1047 associated to the wind generation are considered. The first term is assumed as equal to the National Single Price (PUN), i.e. the purchase price for end customers, computed as the weighted average zonal price. This assumption comes from the following considerations. The value of unbalancing in MSD, that is the difference between the produced electricity and the expected production, depends on the zonal unbalance, i.e. the production of all producers in the zone, which may be positive or negative. Being this information not available, it is assumed that the electricity is bought as MGP price, that corresponds to a positive zonal unbalance. The fact that the electricity is bought at PUN price and not at zonal price, once is bought at MGP price, is always the real case.
