pwrs.core.fdpf.fdpf(Ybus, Sbus, V0, Bp, Bpp, ref, pv, pq, mpopt=None)

Solve an AC power flow using the fast-decoupled method.

Mirrors MATPOWER’s fdpf solver by alternating voltage-angle and voltage-magnitude updates using the reduced Bp and Bpp matrices until the power mismatch satisfies the configured tolerance.

Parameters:

• Ybus (array_like or sparse matrix) – Bus admittance matrix.

• Sbus (callable) – Callable returning complex bus injections for a given voltage magnitude vector.

• V0 (array_like) – Initial complex bus voltage vector.

• Bp (array_like or sparse matrix) – Fast-decoupled Jacobian approximation for active-power updates.

• Bpp (array_like or sparse matrix) – Fast-decoupled Jacobian approximation for reactive-power updates.

• ref (array_like) – One-based reference bus indices.

• pv (array_like) – One-based PV bus indices.

• pq (array_like) – One-based PQ bus indices.

• mpopt (dict, optional) – MATPOWER options struct.

Returns:

(V, converged, iterations).

Return type:
