Juan Eduardo Machado Martinez, Dr.

Juan E. Machado received the B.Sc. degree in electromechanics in 2012 from Technological Institute of La Paz (ITLP), La Paz, Mexico, the M.Sc. degree in applied mathematics in 2015 from Center for Research in Mathematics (CIMAT), Guanajuato, Mexico, and successfully defended his Ph.D. thesis in automatic control from Paris-Saclay University, Gif-sur-Yvette, France in 2019. From January 2020 till June 2023, he worked as postdoctoral researcher at the Faculty of Science and Engineering of the University of Groningen, in the Netherlands. In July 2023, Juan started working as a scientific research assistant at the Chair of Control Systems and Network Control Technology, faculty of Mechanical Engineering, Electrical and Energy Systems, Brandenburg University of Technology (BTU), Cottbus, Germany. In September 2023 he was promoted to the position of Junior Research Group Leader of the Young Investigator Group (YIG) ``Distributed Control and Operation of Integrated Energy Systems,’’ which is part of the project ``Control Systems and Cyber Security Lab (COSYS Lab)’’ of the Energy Innovation Center (EIZ).

Juan’s research interests are within the analysis and control of nonlinear and networked systems, with a strong emphasis on electric and heat grids. During his Ph.D. studies at Paris-Saclay University, he carried out research focused on the analysis and mitigation---through feedback control---of the destabilizing effects that Constant-Power Loads (CPLs) produce on the electrical networks that energize them, particularly in modern AC and DC distribution systems, such as microgrids. As a postdoctoral researcher at the University of Groningen, he worked on modelling, analysis and control of multi-source district heating systems, which are key technologies for a more sustainable heating sector and for robustly and flexibly increasing renewable energy sources into existing energy systems. Juan’s current research goals at Brandenburg University of Technology are aimed at generating dissipativity-based model libraries for the unified, structured and scalable modeling of complex and networked multi-energy systems.
