AbstractOver the years, reliability in electricity distribution system has fostered greater importance in customer satisfaction and its enhancement has been an integral part in planning and operation of distribution utility. Installation of protective devices are generally accepted practices for reliability improvement, however, additional components may also amplify exposure to failures. In addition to the fact that more is not necessarily better, distribution system is also subjected to the 'law of diminishing return'. Therefore, goal is to find the optimal point where, addition of next component adds value, rather than subtracting it. Hence, keeping theories as foundation, pragmatic approaches are also crucial for reliability improvement programs. Three basic techniques; Traditional technique, Automated technique and Integration of Distributed Generation (DG) for reliability improvement has been discussed and analyzed in this thesis. Owing to intangible outcomes of traditional technique, qualitative assessments that include specific guidelines for reliability improvement has been formulated. For other two techniques, quantitative analysis has been done. Most commonly used reliability indices; SAIFI, SAIDI, CAIFI, and CAIDI were computed and found that, more than 50% improvement in reliability can be achieved through these techniques. Integration of DG not only improves reliability but also increases the loadability along with other benefits
