Forwarding to an MSSQL database

We forward messages to an MSSQL database by insering rows into the table(s) we have been granted access to.

Below the schemas for the following messages can be found:

• Solar power
• Wind power
• Battery power
• Limit production power commands
• Set battery operation commands
• Meter power

Solar power

Battery power

Batteries produce two types of messages: regular messages and flash messages. Batteries report flash messages more often than regular messages (typically every second) and contain information that is needed for dispatching algorithms and to forward to the TSO when doing aFRR/FCR. For the strings that can occur in the errors and warnings properties, see Battery power error and warning codes.
