The increased penetration of Distributed Energy Resources (DERs) demands faster system response to fault scenarios due to the DERs' dynamic nature and decentralized allocation. The fastest system response can be achieved when distribution automation has intelligence at the grid edge. Such an approach requires decentralized decision-making logic employed by automation controllers working together to resolve fault scenarios for a pre-defined geographic area. Each participating controller incorporates local measurements and data received from other team members into its decision process for operational switching. The data exchange rates and amount of shared information typically limit the number of devices in one team. This potentially presents an engineering challenge for the large-scale deployment of the distribution automation system with decentralized architecture. To overcome these engineering challenges, the authors are introducing a bridging concept where multiple teams with automation controllers can share relevant information. Each bridge can connect two teams, thus expanding the overall scalability of the distribution automation system. This concept optimizes the IEC61850 data management to simplify the communication infrastructure and configuration. This paper includes the system's governing rules, development phases, and operation examples.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131983355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to concerns for possible low-order resonances, caused by the large amount of cables, studies have been conducted to investigate the risk of temporary overvoltages following transformer energization in the future power system around Stockholm. It was found that the system has a first parallel resonance point close to 150 Hz which is a possible concern when energizing transformers. However, time domain simulations showed that, despite several worst-case assumptions, the risk of severe overvoltages in the studied cases is small, especially when considering the inclusion of loads.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131323579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Significant value can be extracted from these archives by using them to support studies such as frequency response analysis, small-signal stability analysis, and power plant model validation. To better enable utilities to perform these studies, the open-source Archive Walker tool was developed. This tool examines PMU data for grid disturbances and periods of interest. Once identified, the data can be further analyzed inside Archive Walker or exported to specialty tools. In this paper, the various disturbance detectors available in Archive Walker are described, and its interactions with other openly-available tools are highlighted.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133376319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was performed under laboratory conditions. The overall electrical and mechanical performances of insulator were tested according to IEC 61109 after visual inspections and hydrophobicity class measurements. Thereafter, the mechanical strength and dielectric strength of high temperature vulcanized silicone rubber (HTV-SR) sheds were examined; furthermore, physicochemical analyses were conducted on the shed specimens. The results showed that the SR shed represented a very slight decrease in hydrophobicity, tensile strength, elongation at break, dielectric strength and have a stable chemical structure. It was demonstrated that the composite insulator with advanced HTV-SR sheath has long-term lifetime even operated under the extremely environmental stresses.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132347739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The new standard mandates having at least one (out of three) communication protocol in order to facilitate sending commands and receiving status to and from the DER. This new requirement creates a number of challenges for utilities attempting to integrate DER assets onto their grid system. This paper describes a new 3-tier conceptual architecture that is built on an existing anti-islanding (AI) foundation. Named DERCOM, this new architecture is optimized to provide a scalable and flexible communications network for DER integration, as required by the 1547–2018 standard.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115281235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fiber link carries measurement information from the sensor to an electronics chassis faraway. The optical cable can be wrapped around the main high voltage/current conductors to reduce cost. However, a fiber wrapped around the conductor will have an induced Faraday effect due to the power conductor magnetic field. This creates an unwanted current signal pickup. Also, vibrational pickup due to the macro and micro bend loss of this fiber cable is present as well. These unwanted signals interfere with electric current measurement in a very problematic and erratic way. We have demonstrated by employing optical depolarizers in the sensor fiber link a method of reducing unwanted vibrational and current pickup in the sensor.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115710161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The selection of the voltage control station (slack) is described together with the algorithm of selection of optimal voltage control scheme and the algorithm of optimization of voltage set points.

Materials improvements have led to greater output ratings and smaller physical sizes. However mandatory energy efficiency requirements by the US DOE and physical design restraints for smaller units have resulted in designs that are not limited by the rated temperature rise and loading guides have struggled to accurately reflect true capability. Distribution Transformer loading studies show generally light loading but confused load-ability. New high thermal class fluids and improved solid insulations for liquid filled transformers coupled with increased electric vehicle charging and greater heat pump use, suggest new dual nameplate ratings for distribution transformers. The base rating would continue to reflect traditional 65°C parameters. The second rating would be the nameplate kVA rating based on thermal class of the insulation system. This paper shows the usefulness of the proposed change.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122539998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
