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

The communication for the control of Distributed Energy Generation (DEG) in microgrid is discussed. Due to the requirement of real-time 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.
