This New type of power system will be given a variety of renewable energy, energy access needs to implement more comprehensive perception, therefore, in order to solve the traditional Internet of Things (IoT) perception research methods in network information perception accuracy of defects under complex conditions, this paper proposes a sense of renewable energy were calculated based on edge and the technical implementation of couplet system comprehensive perception. Firstly, a cloud-edge-end three-layer distributed IoT sensing framework is constructed. Secondly, all kinds of IoT related data of renewable energy are collected and sent to the cloud. Then, RBF-based state monitor and good state baseline are constructed to accurately perceive the IoT of renewable energy. Experimental results show that the proposed model has high accuracy and provides an effective method for IoT sensing of renewable energy.
