Communication Infrastructure for Smart Microgrids
Published in Sasi K. Kottayil, Smart Microgrids, 2020
A well-defined message format and sequence of messages are required for communication among devices developed by the different vendors. The synchrophasor standard defines four types of messages – namely, data, configuration, header and command. Command messages are sent from PDC to PMU for giving various commands for configuration and control. Data messages are sent from PMU to PDC which contain information about the synchrophasor measurements and various other status parameters and measurements. Configuration messages are also sent from PMU to PDC and these have information pertaining to the data types, data calibration and other metadata. Header messages are again from PMU to PDC and these contain human readable information provided by the user. The data message format is shown in Figure 3.45.
Introduction

The message format completely defines the structure of the message, i.e., it defines the set of fields that constitute the message by defining the width of individual fields (most commonly in bits, bytes, or words), the applied coding scheme (e.g., binary, ASCII, Unicode, ASN.1), and optionally legal values (e.g., constants in binary or some symbolic form or value intervals).

The implementation framework is equivalent to the grammar of the language in the RosettaNet standard. It is mainly used to customise the message format, the content of the message, network infrastructure, and security mechanisms. REF provides a common protocol to provide the transmission service of business flow. It takes an XML standard format to exchange secure messages and mutual understanding (Pan et al. 2019; Wu et al. 2019; Chen et al. 2019a, 2019b; Liu et al. 2019).
