Special Issue Information Dear Colleagues, Smart grid is considered as the next-generation power grid infrastructure, with advanced information and communication technologies (ICT) to control and optimize power generation, transmission, and distribution. The Internet of Things (IoT) has been implemented in smart grids to enhance the efficiency, availability, and reliability of power systems by supporting various network functions throughout the generation, transmission, distribution, and consumption of electric power. IoT devices such as sensors, actuators, and smart meters have been deployed to monitor various areas in the smart grid ecosystem. Smart grid is arguably the largest and most complex IoT implementation in the world as the smart grid can potentially connect millions of IoT devices distributed in very large areas running different communication protocols. Artificial intelligence (AI) can have a key function in synthesizing and discovering valuable insights from the increasingly massive and complex data generated from IoT-integrated smart grids. AI techniques can also be used to automate and optimize the smart grid. This Special Issue focuses on the issues around the Internet of Things, edge computing, and artificial intelligence in smart grids. Topics of interest for publication include but are not limited to the following: Internet of Things and edge computing implementation in smart grid systems; Artificial intelligence implementation in smart grids; Cybersecurity of IoT-based smart grids; Data analytics in IoT-based smart grids; Renewable energy and smart grids; Smart cities and smart grids Dr. Bernardi Pranggono Dr. Hongwei Zhang Guest Editors Manuscript Submission Information Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website.
