This demands that legacy devices perform a variety of advanced grid-support functions in addition to their traditional operation. A hybrid smart transformer (HST) and its protection scheme against damaging high voltages have been proposed. In this paper, the proposed hybrid bypass protection approach is evaluated in a typical substation protection environment involving a group of protection devices. These include a differential relay, feeder protection relay and a SEL-751A as a secondary bypass protection for the proposed HST module. The results from a laboratory-scale hardware prototype are included to verify the effectiveness of the proposed approach. The hybrid bypass protection approach performs as desired under all scenarios without interfering with the normal operation of typical substation protection devices. The proposed protection scheme finds a myriad of applications under the exponentially increasing inverter-based resources (IBRs) that demand robust protection against faults on the grid.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124404827","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}

Yet, models of grid-forming converters are still at best scarce. This paper presents a modelling approach to derive a small-signal representation of a synchronous power converter-based grid-forming power converter. The small-signal models take into account control dynamics of all the control layers such as the current controller and power controller. From the derived model, eigenvalue analyses are carried out to propose reduced models with different levels of computation complexity to meet the requirement of the applications. The proposed approach is validated through simulations under various conditions.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114563057","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 a hardware-in-loop (HIL) test-bed based approach to investigate the performance of islanding detection schemes on a distribution feeder. This approach facilitates the assessment of protection system performance under more realistic conditions by emulating actual devices and a distribution system. The results are based on an actual case study that is outlined to show the effectiveness of existing passive anti-islanding schemes and assess the impact of a DVC on islanding detection.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117008611","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}

Each voltage level have AC/DC and DC/AC conversion stages allowing for testing of two MV and two LV PECs simultaneously. The interface between voltage levels is facilitated by a line frequency transformer and two mechanically coupled induction machines. The paper presents the principle functionalities of the designed power circulation test platform with insights into considerations on safety, communication protocols, controllers, hardware protection and system control for a reliable and safe testing of kVA rated LV and MV PEC systems. The designed test platform features calorimetric power loss measurements enabled by high precision coolant temperature and mass flow transducers.
