All Known Implementing Classes:

DefaultNrSolver, ZbrNrSolver

public interface INrSolver
extends org.eclipse.emf.ecore.EObject

A representation of the model object 'INR Solver'. Loadflow NR solver interface. InterPSS provides a default implementation DefaultNrSolver. It could be replaced with a a custom NR solver implementation. Its implementation object in general contains an AclfNet object

Method Detail

setAclfNet

void setAclfNet(BaseAclfNetwork<?,?> aclfNet)

set the containing AclfNet object.

Parameters:

aclfNet - AclfNetwork object

formJMatrix

ISparseEqnMatrix2x2 formJMatrix()

form J-matrix. This method is called to create [A] of eqn [A][x] = [B] form J-matrix for NR solver

setPowerMismatch

void setPowerMismatch(ISparseEqnMatrix2x2 lfEqn)

set the power mismatch to the right-hand side of the eqn [A][x] = [B] set AclfNet object bus mismatch to the [B] vector of the Sparse Eqn

Parameters:

lfEqn - sparse equation

updateBusVoltage

void updateBusVoltage(ISparseEqnMatrix2x2 lfEqn)

After solving the eqn [A][x] = [B], [x] is stored in [B]. Use [x] to update the AclfNetwork object update AclfNet object bus voltage using the info stored in the [B] vector of the Sparse Eqn at the end of an iteraction step.

Parameters:

lfEqn - sparse equation

updateBusVoltage

void updateBusVoltage(ISparseEqnMatrix2x2 lfEqn,
                      double scaleFactor)

After solving the eqn [A][x] = [B], [x] is stored in [B]. Use [x] to update the AclfNetwork object update AclfNet object bus voltage using the info stored in the [B] vector of the Sparse Eqn at the end of an iteraction step. The scale factor is used for non-divergence Loadflow implementation.

Parameters:

lfEqn - sparse equation

scaleFactor - scale factor

updateBusVoltageNonDivergent

boolean updateBusVoltageNonDivergent(ISparseEqnMatrix2x2 lfEqn,
                                     double tolerance)

After solving the eqn [A][x] = [B], [x] is stored in [B]. Use [x] to update the AclfNetwork object. This method is for non-divergent LF implementation. It search along the [x] to find a point where mismatch is min update AclfNet object bus voltage using the info stored in the [B] vector of the Sparse Eqn and the non-divergence method at the end of an iteraction step.

Parameters:

lfEqn - sparse equation

tolerance - tolerance
