Energy Internet integrates small-scale renewable energy systems, electric loads, storage devices, and electric vehicles for effective transaction of power backed by emerging technologies such as Internet of Things, vehicle-to-grid, and blockchain. 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. Editorial on the Research Topic Editorial for the research topic: Internet of energy for renewable energy- based decarbonized electrical energy systems This research topic aims to highlight the current state-of-the-art technologies in digitalized smart grids, including renewable energy and others. Companies like Tesla, CATL, and Fluence are deploying battery farms that can store megawatts of solar power and release it on demand. Meanwhile, “smart grids” enabled by AI and real-time data are helping to balance supply and demand dynamically. These digital backbones allow utilities to shift. Implementing the Internet of Things (IoT) has become commonplace in the power grid, especially with the evolution of smart grids. This paper examines the role of the IoT in optimizing the integration and management of renewable energy sources, such.
