This paper presents the ability of a three-phase distribution linear state estimator (DLSE) to detect various types of synchrophasor bad data. The DLSE is the first application layer that pre-processes the synchrophasor data and produces state estimates for all observable nodes of the system. This work represents the DLSE software for real-time monitoring, analysis, and situational awareness of the Commonwealth Edison Company (ComEd) Bronzeville Community Microgrid (BCM). The DLSE software platform, used for state estimation, can perform observability analysis, optimize distribution phasor measurement unit (PMU) placement, identify topology change, and detect bad data. This paper focusses on the software's module that supports bad data detection. Demonstration of the PMU-based platform was performed in ComEd's real-time digital simulation (RTDS) enabled Hardware in the Loop (HIL) environment.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122591157","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}

These two load cases are NESC Rule 250B and NESC Rule 250D. Load case NESC Rule 250B “Regional District Loads” is a Deterministic load case which originated in 1908. After several catastrophic failures in Iowa in the 1990s from ice and wind loading, engineers agreed there was a need for a new load case which more accurately accounted for combined ice and wind loads. Engineers analyzed years of meteorological data and created the load case known as NESC Rule 250D, “Extreme Ice with Concurrent Wind Loading.” NESC Rule 250D is a probabilistic load case with a 50-year Mean Recurrence Interval. The Extreme Ice and Concurrent Wind Map, NESC Rule 250D, was first published in the 2002 edition of the NESC, and the NESC specified a Load Factor = 1.0 to be applied to the NESC Rule 250D loads. The NESC Rule 250B with the NESC required load factors (Vertical = 1.5, Trans Wind = 2.5, Trans Wire Tension = 1.65) often results as the controlling load case. This paper will discuss the structural analysis of a 90-degree self-supporting steel deadend from a 345 kV line. This analysis will compare the base reactions for this structure for the 38 unique/overlapping load regions that exist between NESC Rule 250B and NESC Rule 250D within the continental United States. The ratio of the base reactions, (NESC Rule 250B with load factors)/(NESC Rule 250D with load factor = 1.0) will be calculated and mapped. This structural analysis will show that certain regions of the country are designed with probabilistically “high” design loads while many other regions are designed with probabilistically “low” design loads. This can lead to inconsistent levels of reliability between loading regions. Recommendations will be made on how to design structures to have more consistent reliability levels across the continental United States.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130598342","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}

This paper investigates the accuracy of today's distribution reactive power load modeling approaches and explores alternative load allocation processes to improve the spatial diversity of the reactive power load model. The performance of each methodology is assessed on a real utility feeder model ingested with real 15-minute resolution active and reactive power AMI data, providing a full-visibility base case for benchmarking purposes. This paper shows, among other things, that power-based load allocation or an allocation with improved power factor improves the reactive power load modeling by representing the real and reactive power at the feederhead (as compared to the current-based load allocation).","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114083469","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}

However, limited information is published on the aging properties of TUK in ester liquids in accordance with the IEEE C57.100-2011 test standard. This paper provides comprehensive information on the thermal class evaluation of TUK in synthetic ester, canola natural ester, and soybean natural esters tested in the temperature range of 150 °C - 190 °C.

Such information relies on high-resolution (spatial and temporal) outage estimation or prediction, which can only be enabled by developing models using granular, in space and time, data. In this study, to take full advantage of the high spatial and temporal resolution of utility outage data and weather radar observations, the regression problem for developing damage forecasting models is reformulated to consider the time evolving weather condition associated with each outage event. The reformulated problem considers the impacts on outages of variations and cumulative effects of weather conditions not only across the utility's service territory but also over time through the evolution of the storm. Using this reformulated approach, historical utility outage data are used to develop a new and improved damage forecasting algorithm and validate its performance improvement and applicability for more granular outage estimation.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116967852","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 approach focuses on the use of voltage measurements at circuit end-point locations. The combination of sequence and phase voltages are used to detect the open phase condition. Details are provided for circuit measurements and PSCAD simulations used to refine the pickup voltages to help discriminate against conditions where the open phase detection (OPD) should avoid initiating an operation, such as adjacent feeder faults.
