Client: EPCG (Montenegro)

Type: Report

Finishing date: January 2022 (April 2022)

Team: Bogdan Lutovac – Project Manager, M. Vukovic, S. Markovic – Consultants, B. Sijakovic, L. Mladjenovic

Within the report on ’’Technical solution for connection of renewable power generating units to transmission system of Montenegro“, analyses were performed in order to determine connection point and maximum installed capacity of planned renewable power generating units, i.e. solar power plants (SPP) and wind power plants (WPP), considering operational security of the power system and security of supply of local consumers minimizing the connection costs.

Planned renewable power generating units, considered within the Report are the following:

  • SPP Velje Brdo – in the vicinity of Podgorica
  • SPP Briska Gora – in the vicinity of Ulcinj
  • SPP Straziste – in the vicinity of Niksic
  • SPP Dragalj – in the vicinity of Niksic
  • SPP Slano – in the vicinity of Niksic
  • SPP Krupac – in the vicinity of Niksic
  • SPP Cevo – in the vicinity of Cevo
  • WPP Biocki stan – in the vicinity of Niksic

Analyses were performed in the PSSE software tool using referent network models of critical operational regimes for the transmission system operation in conditions of high solar power plant generation. Information on operational regimes were provided by Montenegrin TSO.

Calculations were performed on current network topology and additional sensitivity analyses were performed in order to determine impact of commissioning of planned network upgrades in the near future, defined by Investment plan of CGES and TYNDP 2020 – 2029, as well as the status of ongoing projects.

Type of services provided:

  • Collection of data on potential capacities and geographical locations of planned renewable power generating units
  • Collection of data on critical operational regimes for solar power plant generation
  • Network model creation in PSSE Software tool
  • Modelling of planned power generating units for different connection options
  • Power flow analyses
  • Security analyses
  • Sensitivity analyses of future development of Montenegrin power system
  • Creation of the Report with findings and recommendations
