A New Digital Power Supply System for Fog and Edge Computing

The paradigms of Fog and Edge Computing along with Internet of Things (IoT) promise to make everything, especially smart devices, as part of the Internet environment, where highly-centralized computing infrastructures are gradually decentralized into micro data centers deployed at the edges of each network. As a result, access latency has been reduced dramatically because of the decreases in geographical distance. So far, a great deal of research effort has been focused on how to satisfy the ever-increasing demand for Fog and Edge Computing resources. Correspondingly, the traditional centralized power supply system need to be decentralized among other computing and communications resources. However, how to design, operate and manage a fully distributed power supply system to support the same service agreement level as in cloud computing under fog and edge computing largely remains unknown. In this article, we propose and develop a new power supply system for Fog and Edge computing based on our previous work on digital energy systems. Experimental results based on a real-world case study of the proposed system are presented to validate the effectiveness and efficiency of the proposed power supply system.
