The CIM provides its schema as XSD files which AIIDA needs to respect when emitting the documents. AIIDA supports exactly one CIM document:

• Real Time Data Market Document

AIIDA is able to convert near real-time (NRT) data into the Real Time Data Document. AIIDA has also the capability to receive data in form of the TimeSeries object provided by the Real Time Data Document with the use of the CIM Datasource Adapter.

Real Time Data Market Document

The Real Time Data (RTD) Market Document contains near-real time (NRT) data that is received from a data source in AIIDA. The RTD Market Document is sent as JSON document over MQTT from AIIDA to EDDIE.

Time Series

Time Series in the RTD Market Document represent the values of an AIIDA Record, called quantities in the CIM. Quantities have a type that indicates what the quantity represents as well as its unit. Quantities also provide a quality field that indicates the quality of the quantity.

Type

Currently, the following types are supported:

Value	Description	Unit
0	Cumulative amount of electrical energy consumed from the grid	kWh
1	Cumulative amount of electrical energy exported back to the grid	kWh
2	Real-time power currently being consumed from the grid	kW
3	Real-time power currently being generated and exported to the grid	kW
4	Real-time voltage level on phase L1	V
5	Real-time voltage level on phase L2	V
6	Real-time voltage level on phase L3	V
7	Real-time current flowing on phase L1	A
8	Real-time current flowing on phase L2	A
9	Real-time current flowing on phase L3	A
10	Ratio of real power to apparent power, indicating efficiency of power usage	-

Quality

Currently, the following qualities are supported:

Value	Description
ADJUSTED	The value has been adjusted
NOT_AVAILABLE	The value is not available
ESTIMATED	The value is estimated
AS_PROVIDED	The value is provided as is, without modifications
INCOMPLETE	The value is incomplete
CALCULATED	The value has been calculated
