May 30, 2008 - Wind Power to Bosnia-Herzegovina
STRI is right now performing a project for the independent system operator for Bosnia-Herzegovina (NOS BiH) including a series of measurements to perform analysis of the power quality in the transmission grid. STRI has in addition just received an additional contract from NOS BiH regarding integration of wind power in the same network. This is an important step in the STRI efforts to be a competent international partner for the expansion of wind power that now is happening in many countries.
The increased installation of wind power result in new requirements on the electrical power grid. STRI has through the software SIMPOW® a powerful tool to analyse different solutions. SIMPOW® can simulate complete power systems both for load flow, stability and sensitivity for disturbances. In addition the program can handle different types of wind plants and connections to the grid including AC and DC. STRI is right now working with several projects for the efficient integration of wind power in Scandinavia when SIMPOW® is used.
Since Bosnia-Herzegovina is centrally located in South-East Europe, NOS BiH will play an important role in the continuing integration of the power grid from Greece to Central Europe. The present electricity production is based on fossil fuel and hydro power. Bosnia-Herzegovina also has a larger pump storage plant. The national grid includes 400, 220 and 110 kV. Common with many other countries wind power is planned. But these new plants can be connected in various locations and to various voltages. Since STRI is carrying out a series of measurements in Bosnia-Herzegovina to perform analysis of the power quality in the transmission grid a good cooperation between STRI and NOS BiH has been established with increased knowledge about the specific conditions in this grid. STRI and NOS BiH has therefore for several months been discussing these challenges and together concluded what has to be studied more in detail regarding the integration of wind power.
In a meeting in Stockholm during mid May a cooperation contract was signed. At the same time it was a kick-off for this important project to study the efficient integration of wind power in Bosnia-Herzegovina when Omer Hadzic, Josip Dolic and Vojislav Pantic participated from NOS BiH and Dan Wikström, Math Bollen, Kerstin, Linden and Carl Öhlen participated from STRI. This project will require a detailed simulation of not only the network in Bosnia-Herzegovina but also the connections to the neighbouring countries. Hopefully this project will therefore be the start for an increased cooperation between STRI and other transmission and distribution companies in the region.
