cimpy.cgmes_v2_4_15.LoadGenericNonLinear module

class cimpy.cgmes_v2_4_15.LoadGenericNonLinear.LoadGenericNonLinear(bs=0.0, bt=0.0, genericNonLinearLoadModelType=None, ls=0.0, lt=0.0, pt=0.0, qt=0.0, tp=0.0, tq=0.0, *args, **kw_args)

These load models (known also as generic non-linear dynamic (GNLD) load models) can be used in mid-term and long-term voltage stability simulations (i.e., to study voltage collapse), as they can replace a more detailed representation of aggregate load, including induction motors, thermostatically controlled and static loads.

bs:

Steady state voltage index for reactive power (BS). Default: 0.0

bt:

Transient voltage index for reactive power (BT). Default: 0.0

genericNonLinearLoadModelType:

Type of generic non-linear load model. Default: None

ls:

Steady state voltage index for active power (LS). Default: 0.0

lt:

Transient voltage index for active power (LT). Default: 0.0

pt:

Dynamic portion of active load (P). Default: 0.0

qt:

Dynamic portion of reactive load (Q). Default: 0.0

tp:

Time constant of lag function of active power (T). Default: 0.0

tq:

Time constant of lag function of reactive power (T). Default: 0.0

Documentation of parent class LoadDynamics:

Load whose behaviour is described by reference to a standard model A standard feature of dynamic load behaviour modelling is the ability to associate the same behaviour to multiple energy consumers by means of a single aggregate load definition. Aggregate loads are used to represent all or part of the real and reactive load from one or more loads in the static (power flow) data. This load is usually the aggregation of many individual load devices and the load model is approximate representation of the aggregate response of the load devices to system disturbances. The load model is always applied to individual bus loads (energy consumers) but a single set of load model parameters can used for all loads in the grouping.

EnergyConsumer:

Energy consumer to which this dynamics load model applies. Default: “list”

Documentation of parent class IdentifiedObject:

This is a root class to provide common identification for all classes needing identification and naming attributes.

DiagramObjects:

The domain object to which this diagram object is associated. Default: “list”

description:

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. Default: ‘’

energyIdentCodeEic:

The attribute is used for an exchange of the EIC code (Energy identification Code). The length of the string is 16 characters as defined by the EIC code. References: Default: ‘’

mRID:

Master resource identifier issued by a model authority. The mRID is globally 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 Edition 1, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements. Default: ‘’

name:

The name is any free human readable and possibly non unique text naming the object. Default: ‘’

shortName:

The attribute is used for an exchange of a human readable short name with length of the string 12 characters maximum. Default: ‘’
