The objective of this work was to analyze and quantify the impacts of large-scale RES integration on both the electricity network and market operation in the SEE region, and to prepare the EMI members and regulators to deal with those impacts.

This study included two analyses: first, a study of the changes in the regional electricity market, as the regional markets integrate with a rapidly growing share of RES generation; and second, an assessment of the network impacts of such development, including where congestion may arise and new transmission may be required.

The analysis focused on the target year 2030. Regional market analyses were carried out with Antares software tool providing the impact of large-scale RES integration on wholesale market prices, country balances, cross-border flows and congestion costs. Regional network analyses were carried out with PSS/E software tool and analyzed the impact of large-scale RES integration on the load flows, voltage profiles, secure grid operations and congestions.

In addition to large-scale RES integration in the region, part of the study was dedicated to potential natural gas system development in the region and impact that new gas fired power plants can have on power system operation.

Network and market models (in Antares and PSS/E forms) have been transferred to the EMI participants, with the necessary data and trainings focused on advanced features of these software tools.
