The STATCOM, nowadays being one of the most common shunt-connected FACTS, has matured in this timeframe and is now being employed by many distribution system operators. In this context, its typical application is the mitigation of rapid voltage changes, which are the main cause of voltage flicker. While the relatively low X/R characteristic of a distribution system is not conducive to maximizing the effectiveness of this device, distribution STATCOMs can still be very effective in meeting power quality standard requirements of most distribution systems if planned adequately. This paper presents a real case study deployment of a Distribution-STATCOM in a rural distribution feeder to mitigate rapid voltage changes caused by a nearby industrial park. The presented study demonstrates typical Distribution STATCOM response times are sufficiently fast to mitigate rapid variations, for both load varying and interharmonic caused flicker.","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":"129408073","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}

For the technical analysis, we used Electrical Transient Analyzer Program (ETAP) to practically model the proposed HRES to evaluate feasibility of the optimized HRES in operation modality (e.g., power flow and short circuit analysis). The outcomes of this work verify that the addition of PV and wind units to the Kagbeni's power grid can economically result in a more reliable microgrid enhancing social well-being of Kagbeni's residents.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"47 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":"129523759","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}

A safe and reliable voltage-detection method, which can also be utilized to monitor power availability is therefore a key element and basic requirement for utilities to operate a safe and reliable network. Many of the existing solutions in the United States use temporary voltage-detection devices (such as hot sticks which are discussed below), but these do not allow for monitoring power availability. In addition, these approaches have several technical disadvantages that limit their use. This paper illustrates the challenges with the existing, temporary voltage-detection solutions and discusses advanced and economical voltage-detection systems for permanent and continuous voltage presence detection. It also explains the benefits and additional added value of using these systems in conjunction with cable accessories for switchgear equipment to improve safety, help monitoring power availability, and serve as a basic but fundamental component for deploying smart grids in distribution networks in a cost-effective way. This approach is already helping European utilities to take the first step toward automation and digitization of power grids by providing increased insight into the availability of power in the grid.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"33 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":"134211876","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}

Alternatively, radiometric techniques have experienced an increasing interest which reasons range from the non-invasive principles to the programmability in its execution. On the other hand, much is to be done before such techniques may be widely adopted, especially for the difficulties in properly capturing the correct triggering signal. Based on this scenario, this work presents a brief review of this relatively recent technique and points out items to which researchers should drive their efforts to overcome the related barriers to overcome.","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":"130992221","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 discusses the intermittency of wind and solar energy sources as a factor that makes it necessary to rethink the concept of extreme contingency for systems with high wind and solar penetration. On the premise that contingency definitions should account for weather conditions, the paper proposes to reclassify some contingencies presently considered extreme as normal and introduces new contingency categories. The following contingencies need to be reclassified: the loss of all units of a wind/solar power plant; the loss of multiple units; and the loss of multiple plants. Contingency categories with variation of wind speed and solar irradiance and with multiple wind/solar plants disconnected pre-contingency are introduced. To explore the relevance of these categories, further analyses with adequate representation of wind/solar power plants are needed.","PeriodicalId":241987,"journal":{"name":"2022 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"21 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":"134001610","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 proposes an improved G-C model for a ferromagnetic circuit, which includes hysteresis besides the core saturation. The approach has been applied to model a Continuously Variable Series Reactor (CVSR) with electromagnetic coupling between two electric circuits, a control dc and a controlled ac circuit.
