However, planning Operation and Maintenance (O&M) activities for this kind of system is a challenge in the Pantanal of Mato Grosso do Sul (Pantanal-MS), due to the environmental complexity of this region, marked by seasonality and access restrictions. In this paper the transport route planning for photovoltaic off grid O&M attendance was modelled as the Traveling Salesman Problem (TSP). The inputs considered to obtain the graph of the problem were: the monthly schedule of O&M activities, according to the specification of the systems; flood periods of the region; and the available access routes to the studied area of the Pantanal-MS. Each of these routes was characterized in terms of the most adequate mode of transportation and the mean travel time spent, by the suggested transport mode, in the course of each route. The TSP problem was solved by an optimization method modelled to minimize total travel time and transport mode variation. The results obtained were compared to a solution method based only in logistic time minimization and achieved a significant impact in O&M total cost.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"125 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":"115160583","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 proposes a fuzzy logic-based algorithm developed for the Battery and Load Management System to support the operation of a microgrid with photovoltaic (PV) farm generation. Also, a comparison of financial cost savings is discussed. The software MATLAB/Simulink® was used to develop and simulate the different scenarios.

The e-Park intents to integrate different technologies, such as photovoltaic generation, battery energy storage system, level 2 (mode 3) charging stations, and V2G, to test and validate the solutions. This work achieves this goal by deploying a software tool that manages vehicle recharges and optimize energy resources use, always respecting the electrical distribution grid energy demand limits.","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":"125743018","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 this work, the Monte Carlo methodology was applied to find the uncertainty in luminous flux, when it is measured by means of a far-field goniophotometer. The methodology was applied on three light intensity matrices from three LED sources. The maximum uncertainty found is 1.2 % with a confidence level of approximately 95.5 %. By means of mathematical calculation and simulation it was determined that the distance between the light source and the sensor is the parameter that most influences the uncertainty in luminous flux.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"32 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":"133908672","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}

Although these systems employ single-phase protection devices such as fuses, most utilities have avoided the use of single-phase tripping (SPT) schemes in their reclosers. In order to evaluate SPT implementation feasibility on reliability indices and regulatory report perspectives, this paper presents a detailed distribution feeder secondary voltage analysis when the SPT with three-phase transformers over a radial distribution feeder is implemented. Aiming on a practical application, a real overhead distribution feeder was modeled in Alternative Transients Program, allowing protection algorithm implementation and transient simulation. In this paper, three different types of independent phase-interrupting equipment are evaluated: recloser, lateral fuse and transformer fuse. The obtained results are divided into two approaches: the transient analysis, evaluating the voltage behavior on time domain, and the steady-state sensitivity analysis, evaluating the load level impact on secondary voltage level after the single-pole opening as a response to single-phase-to-ground faults.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"21 5 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":"131177145","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 simplification technique removes nodes and circuits from the original EDS to reduce the number of variables to be considered in the planning stage. The planning problem is formulated as a mixed-integer linear programming problem and its solution determines the optimal allocation of capacitor banks (CBs) and wind-based distributed generation (DG) units. To validate the proposed strategy, three different test cases are analyzed using a 134-node system and its respective simplified 23-node EDS. Numerical results show that similar investment plans for the both systems can be obtained.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"7 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":"131245583","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}

Each voltage regulator makes sure that the pilot bus of the corresponding control zone remains within limits. The proposed control scheme was tested in a large-scale distribution circuit model extracted from the Geographical Information System of a Costa Rican power utility. The tests show that the proposed scheme performs better than the traditional voltage control at generator's terminal. In addition, the proposed scheme increases the cooperation between distributed generators to regulate network voltages.

This storage resource was chosen among others as it is the most promising technology considering their recent remarkable advances. In order to understand the impact on the electric system, firstly a long-term simulation was done so as to determine when this system would become profitable. Then three annual simulations were executed comparing the system operation (i.e. costs, the energy not supplied, CO2 emissions and generation mix), for two cases with batteries (with different participation models), and for the case without them. Finally, the regulatory aspects related to storage penetration that are under debate nowadays in the PJM 1 and UK markets were studied in order to learn some lessons for the development of an adequate regulatory framework in Uruguay. It was found that a lithium ion battery of 80 MWh/20 MW becomes viable by 2039 and its annual operation can reduce the energy the system fails to deliver, the annual thermal generation, CO2 emissions and the system’s marginal cost. Moreover, some barriers and business opportunities were found. If barriers are removed and new opportunities are developed batteries could become viable before.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"15 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":"122457153","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}
