more robust handling of voltage angle difference limits #267

Closed michaelbynum closed 2 years ago

michaelbynum commented 2 years ago

Summary/Motivation:

The computation of bounds for the auxiliary variables c = v_f * v_t * cos(dt) and s = vf * vt * sin(dt) had bugs. This PR uses interval arithmetic to improve the robustness of these computations and adds tests.
