Guest Editorial for the Special Section on Instrumentation and Measurement for Smart Energy Systems

The IEEE Open Journal of Instrumentation and Measurement (OJIM) took its first steps in 2022 and opened a new and exciting venue for contributions on emerging topics from experts in the field. One of the long-standing subjects in the context of instrumentation and measurement is represented by power and energy measurements. In recent decades, this, so to speak, rather traditional field of research has received a new and impressive boost from the evolution of the industrial and economic context, but also from the pressing need to face the environmental problems affecting our Planet, whose mitigation demands a green revolution. Pursuing decarbonization means migrating from fossil fuel toward the intensive exploitation of renewable energy sources. A transition of such a magnitude relies on the ubiquitous presence of electricity and requires the electrification of most of our consumption. All these objectives ask for a new paradigm for energy systems, which shall combine centralized and distributed renewable energy generation, local energy storage, integration with electric mobility, communication, advanced automation, etc.
