A Reliability Model to Local Area System Capacity Adequacy Assessment

One of the important issues that electric utilities worldwide are facing in today's competitive electricity market is to provide electricity with adequate power quality and reliability at a reasonable rate. This paper presents a simple but practical reliability method that is easy to use by practicing utility engineers in planning local area network capacity. The simple method utilizes basic and widely used standard reliability models for series and parallel configurations in conjunction with customer damage functions in complementing the current deterministic planning criteria in-use to increasing the local area transmission capacity for improved service reliability to the customers in a major load center. The practical reliability cost - benefit based methodology is illustrated using a practical area transmission system example with actual loading conditions in the local area network.
