Rodney Itiki

Postdoctoral Research Associate

I am currently a Postdoctoral Research Associate in ORNL’s Power Systems Resilience group within the Energy Systems Integration & Control Section, Electrification and Energy Infrastructures Division, Energy Science and Technology Directorate, focusing on power system resilience and collaborating with industry, national labs, and academic members on research related to energy systems. I earned my PhD in Electrical Engineering from the University of North Carolina at Charlotte in 2023 and hold a Master’s and Bachelor’s degree in Electrical Engineering from the University of São Paulo, Brazil. I served 19+ years in engineering companies (WorleyParsons, CNEC and Frontenge Engineering), with extensive experience with electrical design and specification of gas and hydropower plants, chemical facilities, mining, offshore platforms, and general industries. My research interests include Electrical Engineering (power systems), grid integration, renewables, wind power, HVDC, super grids, transmission systems, electric vehicles (EV), power electronics applications, offshore power systems, submarine cables, marine hydrokinetic turbines, extreme weather models (hurricanes), pumped storage hydro and electromagnetic transient (EMT) component modeling.

  • 2000 - 2015 Electrical Engineer VI with CNEC WorleyParsons, Brazil

Design of power generation and distribution system in medium voltage (up to 18 kV), low voltage (up to 480Vac and 125Vdc), single line diagrams in Autocad or Microstation, three-line diagrams, diagrams for interconnection of measurement, control, and protection panels, cable sizing, cable list, substation electrical room layout. Assessment of existing field conditions, engineering documents search, and as-built survey. Supervision of electrical designers for schematic diagrams, cable tray layout, grounding and lightning protection plant, lighting plant, electrical material takeoff, and cable cut schedule. I was a specialist in charge of power system studies (simulation of short circuit, load flow, motor starting, battery sizing, capacitor bank sizing, harmonics studies, protection coordination, relay settings in PTW of SKM). For my protection coordination studies, I have some brief experience with digital relays from SEL, ABB (REF), Siemens (7SJ), and GE Multilin. I wrote technical specifications of step-up transformers, generator circuit-breakers, HV substation, stepdown transformers, 13.8kV, 4.16kV and 480V switchgear, 480Vac motor control centers, LV switchboards for 220Va/110Vac, and the HV switchyard and substation package, and scope of work statement. I prepared drawings of the hazardous area classification plan. I prepared a Technical Bid Evaluation of MV and LV electrical equipment and evaluated and made comments on vendors' documents. I provided technical assistance to field assembly and construction. I provided training and supervision of junior engineers and designers. I performed quality control of engineering documents produced by the designers. I elaborated proposals for engineering services with workforce estimates and expected delivery time/cost. I conducted remote technical assistance to the field assembly and construction. I was also in charge of collecting relevant data from mechanical, civil, piping, process engineering, and standards of the client for the electrical design of the EPC project. Reason for leaving the company: Layoff due to sharp drop in oil prices, and economic recession in Oil & Gas sector in Brazil.
