Abstract
This study was carried out with two main objectives. Firstly to investigate different types of load modelling in reliability or CIC [customer interruption costs] evaluations to obtain an understanding on how these evaluations are performed and identifying the benefits or limitations of existing models. Secondly to develop several load modelling approaches, including a time dependent beta PDF load model, which are simulated using an appropriate simulation technique and software. A comparison using historical load data based on South African residential customers and shops (used as commercial customers) with the different load models is performed and their impact on the calculated reliability or cost indices are analysed. The analysis shows that the reliability and cost indices resulted in different values of varying degree as compared to the base case (average load model) when using reconfiguration with sufficient spare capacity.
