  Jul 2018 - Dec 2019

  Power System Engineering Intern

  Team: Expansion Planning StudiesActivities:· Conducted power flow and short-circuit studies to assess new connections to ISA CTEEP's concession facilities.· Conducted power flow and short-circuit studies to analyze necessary reinforcements in the transmission system of the state of São Paulo in collaboration with the National Electric System Operator (ONS) and Energy Research Company (EPE).· Participated in studies within the São Paulo Transmission Study Group (GET-SP), particularly in the industrial region service study of the municipalities of Jaguari, Mairiporã, and São José dos Campos.· Developed VBA macros to automate short-circuit simulations in ATP, validating the reduced model of the system under analysis with the complete model in ANAFAS software - Simultaneous Fault Analysis.· Created VBA macros to execute and display statistical simulation results in ATP, used for studies on energization, load shedding, single-pole, and three-pole reclosing of transmission lines.· Contributed to electrical studies in fundamental frequency and electromagnetic transients for the Basic Project of the Lorena substation.· Conducted studies for sizing lightning cables using ATP and OpenDSS.· Participated in studies of ISA CTEEP's Five-Year Plan, evaluating the loading of all its grid transformers up to five years ahead in accordance with the distribution companies' predicted demand.· Conducted strategic investment analysis studies using decision support tools.· Followed up on R&D projects involving energy storage and FACTS.· Developed an internship project on the application of batteries for frequency support prior to the integration of the second bipolar HVDC link from Xingu, operational since August 2019, using ANATEM software - Transient Electromechanical Analysis.· Established relationships with various stakeholders in the electric sector.· Participated in the XXV SNPTEE - National Seminar on Electric Energy Production and Transmission.

  ONS - Operador Nacional do Sistema Elétrico

  Jul 2021 - Jun 2023

  Team: North and Northeast Electrical PlanningActivities:· Engaged in setting up power flow study cases for short and long-term outage planning (month ahead, four months ahead, and year ahead), as well as study cases to support analyses for new generation connections and the 2022 New Energy Auctions.· Participated in preparing the Report on the Guidelines for Operation with Monthly Horizon and the Report on the Guidelines for Electrical Operation with a Four-Monthly Horizon from May to August 2022, focusing on analyses of the Northeast grid.· Conducted power flow, power factor, voltage stability, and RMS studies to support the Parecer de Acesso produced by the ONS. This document evaluates access conditions and technical requirements for connecting facilities to the transmission network accordingly with the Brazilian grid code (Procedimentos de Rede), enabling the contractor to sign the Connection Contract (CCT) and the Contract for the Use of the Transmission System (CUST).· Conducted analyses of Pernambuco's state grid supply points (GSPs) to evaluate the loading of all grid transformers up to five years ahead, providing recommendations for transmission network reinforcements.· Contributed to the preparation of analyses and presentations for the 2022 meetings of the Planning Working Groups for the North and Northeast regions.· Conducted analyses of connection points in Pernambuco as part of the 2021 Annual Rehiring of the Transmission System Use Amounts.· Participated in the preparation of the 2023-2027 Medium-Term Electric Operation Plan document (PAR/PEL 2022).· Conducted studies to define system constraints considering new substations and lines expected to start operating by 2027, including a new HVDC link from the Graça Aranha substation in Maranhão to the Silvânia substation in Goiás.· Implemented a new process for setting up power flow study cases, streamlining the generation dispatch step through an optimal power flow (OPF) tool.
