Name Cardinality^? Type Description

Name	Cardinality^?	Type	Description
`market_evaluation_points`	1..*	`MarketEvaluationPoint`	Market evaluation points associated with the EnergyConnection.
`aggregate`	0..1	`boolean`	The aggregate flag provides an alternative way of representing an aggregated (equivalent) element. It is applicable in cases when the dedicated classes for equivalent equipment do not have all of the attributes necessary to represent the required level of detail. In case the flag is set to “true” the single instance of equipment represents multiple pieces of equipment that have been modelled together as an aggregate equivalent obtained by a network reduction procedure. Examples would be power transformers or synchronous machines operating in parallel modelled as a single aggregate power transformer or aggregate synchronous machine. The attribute is not used for EquivalentBranch, EquivalentShunt and EquivalentInjection.
`description`	0..1	`string`	The description is a free human readable text describing or naming the object. It may be non unique and may not correlate to a naming hierarchy.
`location`	0..1	`Location`	Location of this power system resource.
`m_rid`	0..1	`string`	Master resource identifier issued by a model authority. The mRID is unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID. The use of UUID is strongly recommended. For CIMXML data files in RDF syntax conforming to IEC 61970-552, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements.
`normally_in_service`	0..1	`boolean`	Specifies the availability of the equipment under normal operating conditions. True means the equipment is available for topology processing, which determines if the equipment is energized or not. False means that the equipment is treated by network applications as if it is not in the model.
`short_name`	0..1	`string`	The attribute is used for an exchange of a human readable short name with length of the string 12 characters maximum.
`names`	0..*	`Name`	All names of this identified object.

The aggregate flag provides an alternative way of representing an aggregated (equivalent) element.

In case the flag is set to “true” the single instance of equipment represents multiple pieces of equipment that have been modelled together as an aggregate equivalent obtained by a network reduction procedure.

m_rid

0..1

string

Master resource identifier issued by a model authority. The mRID is unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID.

boolean

Specifies the availability of the equipment under normal operating conditions. True means the equipment is available for topology processing, which determines if the equipment is energized or not. False means that the equipment is treated by network applications as if it is not in the model.
