摘要

Diakoptics is a well-known method of tearing electric networks into computationally smaller subsystems. This paper exposes two often-overlooked, important properties related to diakoptics. One is that branches are not required to tear networks; the other is that the order of the boundary network is strongly dependent on the power system formulation variable-a choice commonly made too prematurely during software development. It is concluded that, first, tearing zero-immittance branches (meshes and nodes) offers more disconnection points than branch tearing; second, that tearing meshes can result in less boundary variables than tearing nodes, and, hence, reduce the computation effort of solving the boundary network.
