Characterisation of the aggregated load patterns for extraurban residential customer groups

This paper reports on the results of a study carried out on the basis of information obtained from real case investigations on residential customer behaviour, lifestyle, and usage of the appliances. The aggregated load patterns of single-house customers have been first computed by using a bottom-up approach. Then, the time-dependent uncertainty of the aggregated load power has been assessed from simulations in function of the number of residential customers. Finally, a goodness-of-fit analysis has shown that a Gamma probability distribution, with parameters related to average value and standard deviation of the simulation results, satisfactorily represents the probability distribution of the load power at each time instant.
