Nevertheless, the inherent alternating nature of wind power affects the stability of the grid as it results in frequency variations, voltage deviations, and increased ramp rates. Battery Energy Storage Systems (BESS) are incorporated in the microgrid to alleviate the aforementioned issues and to promote optimal operation by reducing the power fluctuations. Additionally, power firming filters and algorithms are also combined with the batteries for ramp rate curtailment, power flattening, and cost reduction. Widely used filters such as Low Pass Filters (LPF) and Moving Average (MA) filters are capable filters for fluctuating power control but have poor power tracking capabilities. To account for the resultant power lag, bigger batteries are needed which increases the operating costs. This paper presents a Hodrick Prescott Decomposition filter for wind power firming and enhanced power tracking. Simulation results conclude that the proposed methodology has significantly better power flattening and tracking capability than both the LPF and MA filters. As compared to the traditional filters, the proposed filter leads to decreased battery charging/discharging and appropriate state of charge control which in turn reduces the size of the batteries required for optimal operation.","PeriodicalId":120262,"journal":{"name":"2021 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116640723","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 presents a methodology for modeling and simulating EV charging demand in residential distribution systems. The modeling approach can be used to study the impact of unscheduled charging and also for energy management studies. Since each driver or a group of drivers has a particular behavior, the daily EV plug-in profile variations are characterized to show the individual driving behavior. This approach is more suitable for energy management studies and charging coordination algorithms. The impact of unscheduled charging is investigated using the IEEE 13- Node Test Feeder with 601 EVs, which represents a 50 % penetration level. Tesla Model 3 EV is used, and the 13- Node Test Feeder is simulated in the MATLAB software. Statistical studies, using a year worth of data, show the significant effect of unscheduled charging on the quality of the distribution system operation. Feeders that are impacted the most in terms of violating the voltage limit and current limits are highlighted, and the violation statistics are presented.","PeriodicalId":120262,"journal":{"name":"2021 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124928137","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}

Consequently, the need for studies related to the impact of wind turbines on the electrical system has increased including protection of them and associated equipment. For DFIG-based wind turbines, differential protection has recently been proposed, however, there are few studies on this type of application and in this paper it proposes criteria in the decision-making using the Park transform in which, in addition to the restriction current, voltage level and current direction at the stator terminals are considered. In a DFIG operating with 1.51 MW tests of faults internal and external to the protection zone were made, of the single-phase and three-phase type with various levels of voltage drops. Interturn faults in the rotor and stator of the machine were also tested with various levels of defects. So, with the proper definition of the operating logic, it was possible to show the effectiveness of the protection.","PeriodicalId":120262,"journal":{"name":"2021 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127917159","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}

As distribution system operators work towards interconnecting DERs, they experience new issues that require thorough assessment and mitigation. Among these issues, one such example is coping with intensified Temporary Overvoltage (TOV) on un-faulted phases that results from a system reconfiguration that causes the distribution system to no longer be effectively grounded. In particular, inverter-based DERs and/or certain preferred step-up transformer configurations lead to worse TOV levels than those experienced in typical distribution systems pre-DER connection. TOVs pose insulators and surge arrestors at risk. Currently, there remains a gap in distribution planning of most jurisdictions in formulating the aspects of performance grounding and adopting simple and practical measures to overcome the challenge. This paper provides an overview and analytical evaluation of TOVs in modern distribution systems with high DER penetration and introduces mitigation options, including assessment and design procedures of effective ground sources. Two real distribution systems of a Canadian electric utility are presented as case studies to illustrate the problem definition and proposed mitigation strategies adopted in the project execution.","PeriodicalId":120262,"journal":{"name":"2021 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126989862","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 remote control of the circuit breaker and the calculations of the hot spot temperature and the load of the transformer on the low voltage side will be performed by edge computing. The proposed solution aims to provide protection in the low voltage of the distribution grid and provides more information about the main asset of the utility in the distribution grid.
