面向可中断负荷控制的需求响应通信业务优化

需求响应(DR)常态化的发展依赖于高可靠性的信息交互,尤其是在无线传输应用中。为了提升当前DR中可中断负荷控制的通信信道质量,设计了一种基于信噪比和信道增益的自适应空时预编码策略。所提策略结合DR通信需求,在提高信息传输可靠性的同时自适应规避编码引入的额外计算开销。首先,基于中国DR信息交互规范,结合实际信息传输和控制的频度要求,规定DR不同时段传输的通信服务等级。然后,引入可以优化提升信道增益且DR终端计算开销更低的Alamouti编码技术。在此基础上,利用自适应预编码机制的Alamouti编码策略优化信息传输质量。仿真实例验证了所提算法的有效性。

Communication Service Optimization of Demand Response for Interruptible Load Control

The development of demand response (DR) normalization relies on highly reliable information interchange, especially in the applications of wireless transmission. In this paper, an adaptive space-time precoding strategy based on signal-to-noise ratio and channel gain is designed to improve the quality of communication channels for interruptible load control in current DR. The proposed strategy combines DR communication demands. While improving the reliability of information transmission, it adaptively avoids the extra computational overhead introduced by coding. Firstly, based on the DR information exchange specification of China, combined with the actual information transmission and control frequency requirements, the communication service levels for DR transmission are specified in different periods. Secondly, the Alamouti coding technology is introduced to optimize the channel gain and reduce the DR terminal calculation overhead. On this basis, the Alamouti coding strategy of the adaptive precoding mechanism is used to optimize the transmission quality of information. Simulation examples verify the effectiveness of the proposed algorithm.
