Montenegro: Power Network Analysis for Wind Power Integration

In this study analyses of integration of wind power plants in electric power system of Montenegro have been performed. Influence of connection of wind power plants on transmission network has been performed. Time horizon is year 2020. Following analyses have been performed:

• Review of current control practice and Grid code of Montenegro;
• Analysis of wind data and determination of possible locations of new WPPs;
• Analysis of wind penetration in the electric power system of Montenegro for expected (real) topology and characteristic regimes in 2015 and 2020:

• Load flow analysis
• Voltage profile analysis
• Contingency (n-1) analysis
• Detection of "bottlenecks"
• Identification of any limitations on wind power plant penetration.

The main result of the study is list of possible locations of WPPs in Montenegro, proposal of necessary network reinforcements (in order to make transmission system to be able to accept analyzed wind penetration) as well as proposal of criteria for connection of wind power plants to transmission network.

In addition, the goal is to assessment of future needs of power system regulation with respect to new elements in power system (new WPPs, HVDC to Italy and new generation plan) as well as to make definition and assessment of additional costs associated with increasing levels of wind energy has been made. These additional costs should cover the costs of extra reserve, reduced load factors on the thermal and/or hydro plants, modifications to network components and network reinforcements.
