Master's Thesis from the year 2018 in the subject Engineering - Power Engineering, grade: 4.0, Kathmandu University, course: Master of Engineering in Electrical Power Engineering, language: English, abstract: This thesis presents the techno-economic feasibility study and reliability analysis of a hybrid energy system for Kathmandu University (KU), Dhulikhel, Nepal by using the resources available at premises. For the analysis, both on-grid and off-grid cases are considered. Various energy mix models are identified and optimized for the comparison purposes using HOMER (Hybrid Optimization Model for Multiple Energy Resources) software. The results are also analyzed and compared based on their reliability using Monte Carlo Simulation in RAPTOR software. Based on various combinations and simulations, best cost-effective and reliable model has been proposed. From this study, it is found that being a cost-effective model doesn’t mean it’s reliable too. In order to get the reliable supply, one may have to bear the extra cost to provide standby or emergency supply system. So, the cost plays an important role to determine what level of reliability is required.
