Method Detail

setAclfNet

public void setAclfNet(BaseAclfNetwork<?,?> aclfNet)

Description copied from interface: INrSolver

set the containing AclfNet object.

Specified by:

setAclfNet in interface INrSolver

formJMatrix

public ISparseEqnMatrix2x2 formJMatrix()

Description copied from interface: INrSolver

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

Specified by:

formJMatrix in interface INrSolver

setPowerMismatch

public void setPowerMismatch(ISparseEqnMatrix2x2 lfEqn)

Description copied from interface: INrSolver

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

Specified by:

setPowerMismatch in interface INrSolver

updateBusVoltage

public void updateBusVoltage(ISparseEqnMatrix2x2 lfEqn)

Description copied from interface: INrSolver

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.

Specified by:

updateBusVoltage in interface INrSolver

updateBusVoltage

public void updateBusVoltage(ISparseEqnMatrix2x2 lfEqn,
                             double scaleFactor)

Specified by:

updateBusVoltage in interface INrSolver

updateBusVoltageNonDivergent

public boolean updateBusVoltageNonDivergent(ISparseEqnMatrix2x2 lfEqn,
                                            double tolerance)

Description copied from interface: INrSolver

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.
