Dynamic operating envelopes(DOEs),as key en-ablers to facilitate distributed energy resource(DER)integra-tion,have attracted increasing attention in the past years.How-ever,uncertainties,which may come from load forecasting er-rors or inaccurate network parameters,have been rarely dis-cussed in DOE calculation,leading to compromised quality of the hosting capacity allocation strategy.This letter studies how to calculate DOEs that are immune to such uncertainties based on a linearised unbalanced three-phase optimal power flow(UTOPF)model.With uncertain parameters constrained by norm balls,formulations for calculating robust DOEs(RDOEs)are presented along with discussions on their tractability.Two cases,including a 2-bus illustrative network and a representa-tive Australian network,are tested to demonstrate the effective-ness and efficiency of the proposed approach.
