Electricity plays a very important role in the socioeconomic development of a country. The electrical energy is delivered by distribution system to the end users and has vital role in power system. Distribution system condition should be evaluated and monitored properly in order to deliver quality electrical energy for the end users. However, distribution system conditions vary day by day due to changing operation conditions, which are often overlooked by the utility. Assessing the distribution system and analyzing the technical conditions offers hints when to expansion and reinforce the networks. Thus, this study presents an assessment and technical evaluation of existing distribution system of Punakha district by using PSS/ADEPT software. The existing distribution system was never evaluated before; however, load demand is growing rapidly every year. Load flow result indicates that existing distribution needs reinforcement or expansion to meet the load growth effectively. In contrast to the load flow, reinforcement planning is studied with different options. The study also briefly explores on the optimal placement of capacitor and DG in the distribution network for improvement of system loss and voltage profile. The simulation results were encouraging as these technologies have tremendous benefits both technically and economically A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering in Electric Power System Management Thesis (M.Eng.) - Asian Institute of Technology, 2008 Electric power distribution Bhutan Planning Asian Institute of Technology. http://203.159.5.9/ait-thesis/detail.php?q=B02185 http://203.159.5.9/ait-thesis/detail.php?q=B02185 090120 20260818094035.0
