Work Experience

Power Plant Control Algorithms Section Manager

2018 - PRESENT
Siemens Gamesa Renewable Energy
  • Designed, implemented, and validated control algorithms for the power plant controller. Executed validation techniques, unit testing, CI/CD, and DevOps practices.
  • Acted as a software architect, executing high-level design choices and trials to enforce technical standards, like software coding standards. Performed architectural and business vision and specifications coordination between SCADA-EMS-PPC systems.
  • Coordinated and managed the portfolio of a technology development project related to data science and hybrid control techniques applied to the Power Plant Controller as a project manager.
  • Framed the technology project with AI, ML, deep learning, data diagnosis, energy storage system in grid applications (arbitrage, smoothing, peak-shaving, and curtailment), energy storage sizing and behavior, and advanced control algorithms.
  • Managed people in the technical section. Represented the technical section in internal and external meetings and events. Participated in the definition and governance of the technical unit budget.
  • Recruited people for the section while defining requested profiles and performing candidate selection. Guided the section's workforce acting as a technical reference.

Energy Management System, Power Plant Controller, and SCADA for a Photovoltaic Plant

This project involved supervising the industrialization of a 200kVA power converter for energy dispatch in photovoltaic systems and flow batteries, ensuring compliance with European and American regulations.

I worked on designing and implementing algorithms for power converters, focusing on both low-level and medium/high-level control. I also developed algorithms for power plant controllers, SCADA, and energy management systems, all essential for meeting the Grid Code. In addition, I supervised the start of power converters and power plant controllers at a 48.5MW photovoltaic plant in Blandenboro, NC, USA. Finally, I designed and implemented algorithms related to battery management systems.
