In order to connect remote renewable resources to transmission system in the vicinity, tens of kilometers of high voltage tap line is usually required. To minimize the cost and other issues in land and right of way acquisition, renewable energy developers prefer to use the existing structures jointly and route their HV tap line along the existing right of way. When HV tap line is overbuilt to share the same narrow right of way with distribution lines, it will induce voltages and currents on both phase and neutral conductors of existing distribution lines. Excessive induced voltage and current on distribution neutral and phase conductors may occur during normal operation, fault, and transient conditions of the transmission system. Detailed electromagnetic interference studies shall be conducted to assess the impact of overbuilt or parallel transmission line on the distribution system. This paper will discuss the phenomena of electromagnetic interference generated from HV tap line to the parallel distribution lines. Different practical mitigation solutions will be presented as well.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125014549","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 high-level technical challenges associated with microgrids include (1) operation modes and transitions that comply with IEEE1547 and (2) control architecture and communication. In Part I, the emphasis is on the design of an electrical control architecture for an offshore oil drilling platform powered by wind generation. Engineering a distributed control system having safety critical features, requiring real-time performance is challenging. In this follow-up article we introduce the communication framework for the microgrid scenario under investigation. In all communication networks, scholastic delays and performance are inherent. The only feasible approach is to put bounds on the random processes, qualitatively define the worst cases, and build the distributed control system to be resilient enough to tolerate those behaviors. This is the approach taken by this paper. We propose a communication architecture, discuss performances requirements of the sub-systems, and layout network solutions meeting those specifications.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122511082","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}

When these motors stall, they draw two to three times their rated current and reactive power. The motor stall affects the entire power system beyond the duration of voltage drop of the fault resulting in a system-wide impact. This phenomenon is known as fault induced delayed voltage recovery (FIDVR) or slow voltage recovery (SVR). The FIDVR or SVR event is not only influenced by the air conditioner motor penetration but also by the voltage sensitivity of the load composition in the distribution system. In this study, the singlephase induction machine model that is available in the real time digital simulator (RTDS) is used to simulate the stall nature of these high SEER machines. This paper also addresses the effect of distribution system loads on FIDVR and analyzes the effect using RTDS. A group of the machine models are installed in a test power system along with constant impedance (Z), constant current (I), and constant power (P) load models to study the effect of these loads on the stall nature of the single phase induction machines.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127376812","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}
