**Antonio Bracale** received his degree in Telecommunication Engineering from the University of Naples "Federico II" (Italy) in 2002 and the Ph.D. degree in electrical energy conversion from the Second University of Naples, in 2005. Since 2008, he has been with the Department of Engineering, University of Naples "Parthenope", (Italy), where he is currently an associate professor. His research interest concerns power quality, energy forecasting and power systems analysis. He is an IEEE Senior Member.

**Alessandro Burgio** (1973, Italy) is a consultant with over 20 years of experience in the field of electric power systems, energy efficiency and reliability, and design and prototyping of electronic devices for electric power measurement and conditioning. Since 2019, he has been serving with the Italian company Evolvere SpA as designer and analyst of distributed energy storage systems in a national energy community framework. He is also the executive director of a consortium of about 25 municipalities for the collective purchase of electricity in the deregulated Italian market.

Before assuming his current duties, Dr. Burgio has been the project leader of a National Operating Programme Project financed by the Italian Minister of Economic Development; he also served as research fellow and lecturer.

Dr. Burgio's research activities have resulted in more than 60 papers, published in indexed scientific journals and discussed at international conferences; these research activities have also resulted in a patent of a micro cogenerator for net-zero-power dwelling based on a free-piston Stirling engine.

Dr. Burgio is a member of various programs and scientific and technical committees of esteemed journals and conferences. He holds a master's degree in Management Engineering and a Ph.D. in Computer and System Engineering from the University of Calabria, Italy.

**Tomasz Sikorski** (University Professor) received his Ph.D. degree in application of time-frequency analysis in electrical power systems from Wroclaw University of Technology, Poland, in 2005. In 2006, he was postdoctoral research in Laboratory of Brian Science in RIKEN Institute Tokyo. During 2006–2010, he led the postdoc project founded by Polish Ministry of Higher Education and Science dedicated to the application of novel signal processing methods in the analysis of power quality disturbances in power systems with distributed generation. The project was realized in cooperation with Institute of Power Systems Automation Research Center, Poland. He also participated in a project based on agreements between the governments of Poland and Spain focused on wind energy. He received his habilitation in 2014 and became University Professor in 2016. He cooperates with industry and power system operators regarding the monitoring, detection, and analysis of conducted disturbances and time-varying phenomena in power systems. He has published more than 120 papers and holds an international patent with ABB.
