Abstract

The problem of voltage deviation and power loss was mostly addressed in Distribution Systems (DS) due to the usage of non linear loads. Some or all the customers use these non-linear loads which make the operation of the DS in ill-condition. Network reconfiguration, coordinate planning, and capacitor placements are few methods which are used for improving the voltage profile and reducing the losses. A highly effective reliable generation and transmission system may still result in poor energy supply to the customers if the distribution system is operated unreliable. Planning and operation of DS requires quantitative reliability assessment. DS can be operated reliable by accommodating a small scale decentralized Distribution Generation (DG) in a system, by which the losses in the system was reduced and voltage profile was improved predominantly. Placement of DG in DS will improve the system performance, voltage profile, provides continuity of supply to the customers with reduced losses. DS reliability can be evaluated by load point based indices Average System Interruption Frequency Index (ASIFI) and Average System Interruption Duration Index (ASIDI). These reliability indices are needed to be evaluated before and after DG placement to analyze the system performance. A case study was done on the 11 kV Sodium feeder before and after DG placement to analyze the system performance and reliability indices are evaluated.
