Abstract: Abstract The reliability analysis is a crucial phenomenon for the design and maintenance of a microgrid system. In this Chapter, few hybrid techniques are proposed to assess the failure probability and reliability of the microgrid system. An inverter dominated photovoltaic (PV) system interfacing to IEEE 5-bus microgrid system is developed and system performances are evaluated in terms of its failure probability. Considering different design topologies, four different possible cases are presented to analyse mean-time-to-failure (MTTF), sectional and overall failure rates of the microgrid system using reliability block diagram (RBD) technique. Another two hybrid approaches are presented using both fault tree analysis (FTA) and binary decision diagram (BDD) to evaluate the performance of the microgrid system in terms of reliability. Moreover, a comparative study is also executed in order to inspect the effectiveness of the proposed hybrid approaches.
