In recent years the amount of embedded PV generation in distribution networks has increased significantly. Currently, there is no standard approach on how to model the effect of this generation on the network. This paper aims to provide some guidelines on how to model embedded PV generation in distribution networks. A number of approaches are considered the first being a distributed approach to modelling the PV generation with several models located along the LV feeder. Simplification strategies were then identified, with different strategies being more appropriate for different cases. It was identified that for short and medium length feeders with an even distribution of load and PV generation that a single model located in the centre of the feeder would provide acceptable results, while for long feeders a lumped model at the end of the feeder would be more appropriate. The effect of heavier weighting of PV and load at different points on the feeder was also investigated.
