Evaluation of Reliability Indices and Capability Outage Table for an Organised Off-Grid Community
Subject area: Science,Engineering and Technology · Area of research: Electrical Engineering
Abstract
This paper analyzes the reliability of an off-grid electricity supply system for an organized community using the Redemption Camp along the Lagos-Ibadan Expressway, Nigeria, as a case study. The community, with 13,500 customers, has its distribution network divided into six zones. The study identified Zone 6 as the most critical zone, contributing 37.20% to the total system outage duration (SAIDI) but having a minimal impact (5.72%) on its own zone users. Conversely, Zone 3 had the lowest SAIDI (7.23%) but the highest customer average interruption frequency (CAIFI) of 30.19%. Outage impact: The total community outage in 2022 amounted to 911,938 kWh, equivalent to $155,029.4 annually, representing 5.08% of the system's total operation and maintenance cost. Overall, this study provides insights into the variability of reliability indices across different zones within an off-grid system. These findings can be valuable for planning and prioritizing infrastructure improvements to enhance the overall reliability and cost-effectiveness of such systems.
