Dynamic operating envelopes(DOEs),as key enablers to facilitate distributed energy resource(DER)integration,have attracted increasing attention in the past ***,uncertainties,which may come from load forecasting errors or inaccurate network parameters,have been rarely discussed in DOE calculation,leading to compromised quality of the hosting capacity allocation *** letter studies how to calculate DOEs that are immune to such uncertainties based on a linearised unbalanced three-phase optimal power flow(UTOPF)*** uncertain parameters constrained by norm balls,formulations for calculating robust DOEs(RDOEs)are presented along with discussions on their *** cases,including a 2-bus illustrative network and a representative Australian network,are tested to demonstrate the effectiveness and efficiency of the proposed approach.

AIM：To compare the efficacy of single-session 360-degree selective laser trabeculoplasty（SLT） for reduction of intraocular pressure（IOP） in patients with pseudoexfoliative glaucoma（PXFG） and primary open angle glaucoma（POAG）.· METHODS：This is a single-center,prospective,nonrandomized comparative *** older than 18 years of age with uncontrolled PXFG or POAG eyes requiring additional therapy while on maximally tolerated IOP-lowering medications were *** primary outcome measure changed in IOP from *** was defined as IOP reduction ≥20%from baseline without any additional IOP-lowering *** patients were examined at 1d,1wk,1,3,6,9,12 mo after SLT.· RESULTS：Nineteen patients（20 eyes） with PXFG and27 patients（28 eyes） with POAG were included in the *** the visual fields mean deviation was-2.88（±1.67）in the POAG and-3.1（±1.69） in the PXFG groups（P=0.3）.The mean（±SD） IOP was 22.9（±3.7） mm Hg in the POAG group and 25.7（±4.4） mm Hg in the PXFG group at baseline and decreased to 18.4（±3.2） and 18.0（±3.9） mm Hg in the POAG group（P〈0.001 and P=0.02）,and to 17.9（±4.0） and 21.0（±6.6） mm Hg in the PXFG group（P〈0.001 and P=0.47） at 6 and 12 mo,*** number of medications was 2.6（±0.8） in the POAG group and 2.5（±0.8） in the PXFG group at baseline,and did not change at all follow-up visits in both groups（P =0.16 in POAG and 0.57 in PXFG）.Based on Kaplan-Meier survival analysis,the success rate was 75%in the POAG group compared to 94.1%in the PXFG group（P=0.08;Log-rank test） at 6mo,and 29.1%and 25.0%at 12 mo,respectively（P=0.9;Log-rank）.· CONCLUSION：The 360-degree SLT is an effective and well-tolerated therapeutic modality in patients with POAG and PXFG by reducing IOP without any change in number of *** response was more pronounced early in the postoperative period in patients with PXFG whereas there was no statistically significant difference at 12-month follow-up. 〈/tr〉
