dc.description.abstractThe northwest grid network of TANESCO (Tanzania state power company) suffers the stressful condition caused by factors such as worst climate condition affecting hydropower sources (which is 75% of the total generated units), an over exploitation of the existing transmission system and less or no number of new power system projects. Together, the lack of reactive power sources into the system has also resulted in voltage fluctuations. Some indication of the stated severe conditions and methods to relieve the system from voltage instability are researched in this work. The involved grid section was modeled in MATLABTM Simulink, by dividing it into smaller sections and then simulated to obtain the existing condition results. FACTS devices (SVC, STATCOM and UPFC) were applied one after another. Starting with a section up to the entire system, simulated and the results were recorded. The obtained results were compared with those from a system without FACTS. Implemented models were limited to hydropower sources located in the southern part of Tanzania fed at Mtera and the northern part fed at Njiro- Arusha. The applied FACTS improved the voltage condition with the ability of damping oscillations. Application of FACTS in power system, upgrade the grid and reduce the delaying period of its replacement. UPFC provided the most efficient performances of power system when proper location and economic analysis are considered.en_US
