pwrs.core.makeBdc#

pwrs.core.makeBdc.makeBdc_mpc(mpc)[source]#

Build the DC power flow Bbus and Bf matrices.

Returns the B matrices and phase shift injection vectors needed for a DC power flow. The bus real power injections are related to bus voltage angles by:

P = BBUS * Va + PBUSINJ

The real power flows at the from end the lines are related to the bus voltage angles by:

Pf = BF * Va + PFINJ

Does appropriate conversions to p.u. Bus numbers must be consecutive beginning at 1 (i.e. internal ordering).

Parameters:

mpc (MatpowerCase) – MATPOWER case struct.

Returns:

(Bbus, Bf, Pbusinj, Pfinj) for the DC model.

Return type:

tuple

pwrs.core.makeBdc.makeBdc_values(baseMVA, bus, branch)[source]#

Build the DC power flow Bbus and Bf matrices.

Returns the B matrices and phase shift injection vectors needed for a DC power flow. The bus real power injections are related to bus voltage angles by:

P = BBUS * Va + PBUSINJ

The real power flows at the from end the lines are related to the bus voltage angles by:

Pf = BF * Va + PFINJ

Does appropriate conversions to p.u. Bus numbers must be consecutive beginning at 1 (i.e. internal ordering).

Parameters:

  • baseMVA (float) – System MVA base.

  • bus (npt.NDArray[np.float64]) – Bus matrix.

  • branch (npt.NDArray[np.float64]) – Branch matrix.

Returns:

(Bbus, Bf, Pbusinj, Pfinj) for the DC model.

Return type:

tuple

pwrs.core.makeBdc.makeBdc(*args)[source]#

Pf = BF * Va + PFINJ

Does appropriate conversions to p.u. Bus numbers must be consecutive beginning at 1 (i.e. internal ordering).

Parameters:

*args (tuple) – Positional arguments for one of the supported call forms.

Returns:

(Bbus, Bf, Pbusinj, Pfinj) for the DC model.

Return type:

tuple
