mp.form_acp

class mp.form_acp

Bases: mp.form_ac

mp.form_acp - Base class for MATPOWER AC polar formulations.

Used as a mix-in class for all network model element classes with an AC network model formulation with a polar repesentation for voltages. That is, each concrete network model element class with an AC polar formulation must inherit, at least indirectly, from both mp.nm_element and mp.form_acp.

Provides implementation of evaluation of voltage-related Jacobian and Hessian terms needed by some mp.form_ac methods.

mp.form_dc Methods:

For more details, see the AC Formulations section in the MATPOWER Developer’s Manual and the derivations in MATPOWER Technical Note 5.

See also mp.form, mp.form_ac, mp.form_acc, mp.nm_element.
