After years in which the Internet of Things has been one of the main drivers of change in the way we consume, now comes the Internet of Energy. Its aim is to automate and regulate processes, enabling greater energy efficiency and a better use of renewable energies. The Energy Internet represents a transformative paradigm integrating advanced power systems, distributed renewable energy, and digital technologies to achieve efficient, resilient, and sustainable energy management. In any case, this is real if and only if the power grid can handle increased use of renewable energy sources and distributed energy. The Internet of Energy (IoE), as a new concept, transforms the way of energy production, supply, and consumption to fulfill high-energy demands via a smart network of industrial energy producers and consumers.
