摘要：

智能电网家域网中应用认知无线电技术的主要目的是提高频谱利用率。功率控制是提高频谱利用率并实现频谱共享的主要手段之一，其通过减小认知用户间干扰来提高用户信干噪比性能，从而保证认知用户正常通信。研究基于认知的智能电网家域接入网络中三种不同功率控制算法的性能。通过仿真对比可得：三种算法收敛迅速，效率极高，在一定程度上都能降低系统开销，提高网络性能，对实际工程有很好的指导意义。

Abstract:

The main purpose of the application of cognitive radio (CR) technology in the Home Area Network (HAN) of smart grid is to improve the spectrum utilization. Power control is one of the main ways of improving spectrum efficiency and spectrum sharing. By reducing the interference between secondary users (SUs), users' signal to interference plus noise power ratio (SINR) is improved so as to ensure the normal communications among SUs. We study three power control algorithms in the performance of home area access control network of smart grid based on CR technology. Simulation results show that the three algorithms have rapid convergence and high efficiency, which can reduce the system overhead to a certain extent and improve the network performance, thus having very good guidance significance for practical engineering.

Key words:

home Area Network, cognitive radio, pricing function, power control.
