Impact of electrification of residential heating on loading of distribution networks

For network planning and analysis, future residential loads are mostly modelled based on historical data combined with an estimated load increase. However, new technologies arise which change the current residential loads substantially. One of these changes is the electrification of residential heating by (large-scale) application of micro combined heat and power (micro-CHP) and heat pumps. There is not much known about the actual impact of micro-CHPs and heat pumps because the amount of applications is still small. In this paper measurements are analysed and models are presented to estimate the (aggregated) peak and day profiles for one or more of these appliances. It is shown that the modelled profiles are a good representation of the generation and load profiles of micro-CHPs and heat pumps. The profiles can be used for network planning and impact studies of residential heating on the electricity distribution networks
