This is typically done to achieve a more reliable power supply with reduced cost. The work presented in this article is directed toward achieving proportional load power sharing between modular connected distributed generators (DGs) comprising inverters with common ac and dc buses in ac microgrids that are islanded. Two new schemes have been proposed to achieve this, and their performances have been compared with that of a recently proposed decentralized linear adaptive virtual impedance (AVI) variation strategy. The control schemes have been tested for a wide variety of loads and integrated seamlessly with the conventional and inverse droop control approaches for enhanced performance under varying network <inline-formula xmlns:mml=\"http://www.w3.org/1998/Math/MathML\" xmlns:xlink=\"http://www.w3.org/1999/xlink\"><tex-math notation=\"LaTeX\">$text{X}/text{R}$</tex-math></inline-formula> parameters. The novel strategies are also validated on a modified 13-bus system with three DGs using offline simulations on MATLAB/Simulink. Validations using controller-hardware-in-the-loop (CHIL) setups are also carried out for meshed network conditions, different loads, and different DG power ratings and droop controller configurations.","PeriodicalId":50390,"journal":{"name":"IEEE Industry Applications Magazine","volume":"54 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139669101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A fire can be initiated by excessive current (due to an overload or a short circuit) or arcing current. Therefore, both the Canadian Electrical Code (CE Code) Part I and the National Electrical Code (NEC) require the installation of overcurrent protection devices (OCPDs) to detect and clear excessive current. Conversely, arcing current is too low for OCPDs to detect. It could take an electric arc minutes, days, weeks, months, or even years to initiate a fire. Therefore, a new solution was required for detecting those slowly developing arcs. Thus, arc-fault circuit-interrupters (AFCIs) were born. AFCIs are capable of detecting an arcing condition (while still developing) and de-energizing the circuit before the arcing circuit ignites.","PeriodicalId":50390,"journal":{"name":"IEEE Industry Applications Magazine","volume":"3 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, dc systems face technical limitations that require protection from dc circuit breakers. This article deals with the techno-economic analysis of dc solid-state circuit breakers (SSCBs) by involving design, cost, and performance parameters. To clarify the current situation and identify future needs, dc SSCBs are analyzed from three aspects. First, the deciding factors and performance criteria are illustrated. Second, the driving factors, technical challenges, and applications of dc SSCBs are discussed. Finally, the techno-economic analysis of practical SSCBs is elaborated. The presented concepts are evaluated by a 4 kV/100 A dc SSCB prototype as a case study, where the cost distribution among components is discussed. The results show that practicing marketing and economic perspectives in designing dc SSCBs can help to pave the way for advancing dc power system protection and facilitating fully penetrated dc transmission and distribution networks.","PeriodicalId":50390,"journal":{"name":"IEEE Industry Applications Magazine","volume":"8 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
