Example2.Base.Systems.Basic.Data

Power flow data records for network initialization without the use of OpenIPSL Types

Information

This package contains different sets of data records that can be used to initialize the power network on an initial operating point.

Note that the templates in this package do not include the type declarations with nominal attributes provided by OpenIPSL, which therefore leads to different initialization solutions when the data is used as compared with the package Example2.PFData. This is used to illustrate the use of types with nominal values, observe that in the templates here, no nominal values are used, as compared with the package Example2.PFData, where they are. Observe that this is an important aspect as, "the nominal value can be used by an analysis tool to determine appropriate tolerances or epsilons, or may be used for scaling" (see the Modelica Specification, Ch.4.8.6).

For example, in this package the voltage mangitude is defined in Example2.Base.Systems.Basic.Data.PF_TwoAreas.Voltages as:

parameter Real V1;

Meanwhile, for the case of the templates in Example2.PFData, OpenIPSL

parameter OpenIPSL.Types.PerUnit V1;

where the type declaration is:

type Voltage = SI.Voltage(nominal = 1e4, displayUnit = "kV");

This difference will result in different intialization solutions despite having the same power flow data.

It is recommended that the solution provided in the package Example2.PFData is favored.
