An 11 kV steady state residential aggregate load model. Part 1: Aggregation methodology

This paper, which is part one of a two-part series, presents a general methodology for the development of improved aggregate load models for steady state power system analysis. Using the UK residential load sector as an example, the paper shows how component-based low voltage (LV) aggregate load models can be obtained using measurements, statistical and other available data and information on load structure and active/reactive power demands. The presented aggregate LV load models are connected to typical LV and medium voltage (MV) network configurations, in order to obtain correct aggregate load models at higher voltage levels. Part two paper discusses how the presented aggregate load models can be modified to include the analysis the effects of demand side management and microgeneration technologies have on the overall performance of LV/MV networks.
