This paper presents an object-oriented modeling software, LoadLab, for the load analysis of electricity distribution networks. A characteristic feature of LoadLab is that it uses load pattern models where consumption is represented as the sum of the daily and weekly rhythms of consumption, the effects of outdoor temperature on consumption, and random variation. With object-oriented modeling methods we can manage the hierarchical structure of the distribution network which is reflected in the load models. Network load patterns and their confidence intervals are obtained by combining existing load pattern models and consumer characteristic data.
