Application of Spectrum Sensing Technology in Wireless Communication of Smart Grid

In order to meet the needs of modern economic and social development, the concept of "smart grid" was put forward. Cognitive radio (CR) technology was introduced into the smart grid communication system. By perceiving the situation of the external communication environment, the frequency band and bandwidth of the application were adjusted to improve the spectrum utilization. The application of spectrum sensing technology in the wireless communication network of smart grid was studied. On the basis of the existing spectrum sensing algorithm, the strategy of selecting the perceptual algorithm was optimized according to the different business requirements. The results showed that the proposed optimization model had a high accuracy in spectrum sensing. It reduced the probability of communication interrupt. To sum up, the method not only effectively uses the idle spectrum resources, and ensures the large capacity data transmission needs, but also improves the reliability and communication quality of the power grid communication system.
