This poses new challenges for the frequency response of power systems — temporary power imbalances result now in deeper frequency excursions and greater rates of change of frequency with potential operational and protective challenges. Classical remedial actions as under-frequency load shedding, spinning reserves and primary frequency regulation play a central role along with novel technological strategies as synthetic inertia. The assessment of these alternatives for frequency control and protection requires suitable models where topological aspects of the network can be put aside. This paper describes the developing of a new modeling tool that, departing from the time response of the frequency of a system facing power imbalances, builds an equivalent single busbar model. It does so by first computing an approximation of four parameters that capture the essence of the frequency transient for the grid, which then refines using a genetic algorithm. The user can configure the set of lumped equivalent device models present in the single busbar model. Results of its application to the Argentine-Uruguayan system are described and commented.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124805607","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 addition, the inclusion of small scale generation within the distribution network has caused some operational issues. A possible solution to mitigate these effects is the application of smart grids in low-voltage networks. Extensive low-voltage networks with high penetration of distributed generation and the tools, techniques, and procedures available in smart grids have motivated the installation of wireless aggregators in the network, which allows the collection of operation information. Such data collected in the aggregators contributes to a better monitoring of the electrical system and provides insightful information for planners and operators. Additionally, in order to improve the operation of the electric network, a methodology of placement of wireless aggregators is proposed. Within this methodology, each aggregator is considered as a reference to group the wireless smart meters, which are installed at every end consumer. ZB’s wireless communication technology is considered in this paper, which is extensively used due to its low latency, operational cost and packet data. The result of this aggregation has shown to improve the observability of the electrical system.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114365052","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 study focuses on service times analysis of charge points over periods of intense vehicular traffic and for prospective scenarios of high penetration of electric vehicles. The first goal is to quantify performance limits for the current recharging infrastructure and vehicles capabilities under stressful contexts, but at the same time realistic, considering existing data of traffic flows and prospective studies for possible electric vehicles penetration scenarios. Queueing Theory is the underlying framework to tack this part of the analysis. The second part of the study uses Markov Chains, whilst assumes a near future with greater driving range of electric vehicles and seeks to estimate how many additional charge points are required to provide a satisfactory level of service. Main results show that the current infrastructure is capable of fulfilling near future needs, but for some growth scenarios of the electric vehicles fleet, that infrastructure should be updated to sustain mid to long-term recharging needs.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"10 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114001445","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 that regard, this paper proposes a compound method that combines a Logistic Regression predictive algorithm with the concept of Customer Journeys, in order to enhance the accuracy of the fraud detection method traditionally applied in CPFL Energia (a major Brazilian utility). Every interaction of each CPFL’s customer is taken in consideration to track fraudulent customers record and identify suspicious patterns, with the purpose of adding new data to the present model and better refining its outcome, thus reducing false-positives and achieving both greater accuracy and recovered revenue amounts, besides better operational efficiency. The proposed methodology was field tested, resulting in a 2.2 times greater fraud inspection success rate, and the model was effectively implemented on the internal processes of the company’s department responsible for fraud detection and revenue recovery.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":" 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113949850","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}
