微网分布式发电控制中“自然编码”消息的解码

Decoding the `Nature Encoded' Messages for Distributed Energy Generation Control in Microgrid

Shuping Gong, Husheng Li, Lifeng Lai, Robert. C. Qiu

摘要:

讨论了微网分布式发电控制中的通信问题。由于实时传输的要求,系统状态信息采用弱编码或无显式信道编码。为了保护未编码或弱编码的消息的可靠性,系统动态被认为是类似于卷积码的“自然编码”,由于其在时间上的冗余。对于具有或不具有显式信道编码的系统,提出了基于卡尔曼滤波和Pearl置信传播的两种解码过程,其方式类似于传统数据通信系统中的Turbo处理。利用发电机动态系统的线性模型进行了数值仿真,验证了该方法的有效性。

英文摘要:

The communication for the control of distributed energy generation (DEG) in microgrid is discussed. Due to the requirement of realtime transmission, weak or no explicit channel coding is used for the message of system state. To protect the reliability of the uncoded or weakly encoded messages, the system dynamics are considered as a `nature encoding' similar to convolution code, due to its redundancy in time. For systems with or without explicit channel coding, two decoding procedures based on Kalman filtering and Pearl's Belief Propagation, in a similar manner to Turbo processing in traditional data communication systems, are proposed. Numerical simulations have demonstrated the validity of the schemes, using a linear model of electric generator dynamic system.
