Although very beneficial for the environment, their instability caused by weather conditions can lead to power quality issues when connected to the grid. In order to minimize those power fluctuations, a Battery Energy Storage System can be coupled, providing or absorbing energy. This paper aims to review a few smoothing algorithms, such as Simple Moving Average, Double Moving Average, Exponential Moving Average, Moving Median, Ramp Rate, and Modified Ramp Rate, and compare them to the same simulation conditions, a 307.8 k W p solar photovoltaic system, for the purpose of finding the most suitable way to maintain the variation within an acceptable range while preserving the battery health. As the result of the analysis, a modification made on the ramp rate algorithm proposed in this paper that enables the battery State of Charge to return to its ideal level, stands out positively regarding the other methods.","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":"126616505","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 the power grid evolves to accommodate essential reliability services such as virtual inertia from nonsynchronous generators, conventional techniques to estimate frequency face challenges. This paper proposes a new frequency estimation method that can effectively include the inertia contributions from double-fed wind generators (DFIGs). This is achieved through the proposed extended frequency divider formula (FDF) to include the contributions of DFIGs via Thevenin equivalents. The proposed extended FDF does not suffer from numerical issues as compared to existing phasor angle derivative-based approaches. Moreover, the knowledge of the rotor speeds of the synchronous machine and DFIGs as well as of the network admittance matrix allows estimating the frequencies of all buses in the grid, thereby significantly improving system situational awareness with a limited number of measurements. Numerical results on the IEEE 39-bus power system with DFIGs show that the proposed method achieves more accurate bus frequency estimations than the original FDF formula and other approaches based on the numerical derivation of the bus voltage phase angles.","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":"122955177","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}

GIS and GILs are characterized by a high degree of reliability and long lifetime. Any failure in these types of equipment directly reduces grid reliability and increases maintenance costs. The failure analysis divulges that insulation deterioration is a principal factor in most of the breakdowns of GIS. Since gas-insulated apparatus are sealed structures, it is difficult to find internal incipient faults from outside. As such, intelligent condition-based asset management tools to detect the incipient faults to avoid functional failure is mandatory. Online partial discharge (PD) detection has been proven as the most effective tool for insulation degradation diagnosis. Both ultra-high frequency (UHF) technique and acoustic means have been popularly used in PD detection to enable the reliable, cost-effective life extension of existing plants. This paper presents state of the art in GIS/GIL online UHF PD diagnostics experienced by DEWA. It also explores the advantages of online PD monitoring as persuasive condition-based techniques for timely detection of potential faults. The paper also demonstrates real-life scenarios related to PD monitoring which increases the reliabilty of the grid.","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":"124664434","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}

In case of touching the ground, a High Impedance Fault (HIF) can occur. This specific situation can lead to a detection fail for the protection system. It is due to the fact that the HIF does not produces enough fault current to operate conventional protection systems or fuse. On the other hand, if the cable does not touch any surface, the upstream protection equipment will not sense any overcurrent in its system; otherwise, it will sense a current reduction and the protection will not operate. To undertake this problems in a simple protection logic, this paper presents an implementation of a symmetrical component logic to enhance the traditional protection systems, mainly in a scenario where there are single-phase transformers. Those assets are source of unbalanced loads. Moreover, this paper presents a way to implement the logic proposed into the commercial IEDs. Lastly, performance results are showed through IED logic simulation software, and on-field performance is 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":"133946443","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}

Charging depends on the manufacturing technology, the methodology established by the manufacturer, and must be controlled depending on the voltage and current, considering the state of charge of the batteries, the power sources, and the load. In this work, a control for a dispatchable power source connected to the distribution network for charging battery banks in isolated microgrid is proposed, considering the dynamics of a distributed generation system. This control was implemented through a PAC (Programmable Automation Controller), considering two main charging approaches: a) a full battery bank charging, made when the battery state of charging reach the minimum permitted level, and b) a partial battery bank charging, made when the 90% of the maximum state of charging is not reached in the day. A real and consolidated system was used as a case study: this system is the isolated microgrid with generation distributed in Ilha Grande, northeastern Brazil.","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":"114981151","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}
