Research and Application of Carrier Aggregation Technology in Smart Grid

Due to limitation of the optical fiber communication network coverage, the wireless technology is usually adapted to meet the requirement of applications in the smart grid transmission and distribution. In this paper, we study the electrical communication with integrated access technology to establish communication with the whole business model of electricity based on the same frequency and carrier aggregation TD-LTE230 MHz power wireless broadband system. We divided the power 230MHz private spectrum into the 40 discrete frequency bands by the carrier aggregation (CA) technology. Meanwhile, we present a novel scheme to achieve carrier aggregation application by the digital circuit according to the characteristics of 230MHz band. The transmission rate, spectrum efficiency calculations and analysis results show that the carrier aggregation technology can effectively improve the spectrum efficiency, rational use of 230MHz spectrum resources.
