What is the Energy Internet Project
The Energy Internet is a proposed framework for maximising the efficient collection, distribution, and management of energy sources using networked computing and communication systems. Its features, such as plug-and-play mechanism, real-time bidirectional flow of energy, information, and money can lead to significant benefits and innovation in electricity production and. Answering this question is at the heart of the so-called “Third Industrial Revolution,” which seeks to integrate renewable energy sources with Internet connectivity, develop digital manufacturing technology, and support green industry. In other words, the goal is to achieve sustainable production. The German Federal Ministry of Economics and Technology also launched E-Energy (Internet of Energy) about the same time. We revisit some attempts to design a digital grid similar to the internet, including packetized management of specific loads (electric vehicles.
