Abstract: High penetration of renewable micro-grids in power distribution system has given rise to unique reliability issues owing to their intermittent nature. Moreover, individual reliability indices of power distribution systems tend to present conflicting results. Therefore, a single index to quantify the overall reliability of substations is necessary. In essence, this work proposes a Composite Reliability Index (CRI) for renewable penetrated Indian power distribution system. In this work, reliability indices are normalized using Z-scores, followed by Principal Component Analysis (PCA) for weight decision. Particularly, indices recommended in IEEE Std 1366-2003 and practiced by Indian utilities in real-time are studied. Finally, results of test-systems data analysis show that proposed CRI can expedite the reliability assessment process in multiple permutations of systems and operational choices.
