Abstract

This paper concerns the quantification of the costs that a distributor must support to enable the new market scheme and the participation of new potential competitors to the ancillary service market. Starting by available open data and GIS the value of distributed resources and active demand in the market for system services has been assessed. Representative models of the network beyond the TSO/DSO interface have been developed in order to evaluate the operation extra-costs for solving contingencies. The impact on the flexibility (quantity) potentially offered by a distribution network and on the price of the bids in the ancillary service market has been calculated by applying the proposed methodology to real world cases.
