Power Market Analysis for Two Proposed Transmission Lines between Albania, Bulgaria, and Macedonia

GTMax simulated power system operations for 2005 and 2010 for two basic scenarios. In the first, the power systems in Albania, Bulgaria, and Macedonia operate independently and do not trade, sell, or exchange energy or capacity with one another or with the Greek power system. In the second, power exchanges are allowed among the three utility systems across the new transmission lines. GTMax also determined the hourly power transactions, optimized the exchanges among the utilities, and determined market clearing prices in each node of the network.

Role of Hydro in a Regional Electricity Market in Southeast Europe

Eight Balkan countries were modeled in the USAid-sponsored study

  • Examined regional electricity market and trading via new interconnections
  • Collaborated with numerous utility experts from the region
  • Studied open and closed market scenarios
  • Analysis performed for 3 hydro-logical conditions: wet, average, and dry

​The objective function for optimization was to maximize net revenues by finding a solution that increases income while keeping expenses at a minimum.
