A domain architecture for solving simultaneous nonlinear network equations [power system simulation]

Abstract

This paper describes an approach of systematic software reuse by defining a domain architecture. An appropriate domain model formulates network and connected entities with behavior leading to systems of simultaneous nonlinear equations. An object-oriented framework is derived from the domain model and represents a core reusable asset. The domain architecture provides an environment for an adaptive usage of this framework. The person who reuses the domain architecture specifies an application by sets of symbolical expressions assigned to the fundamental nport types and functions representing sums of any variable type. Further the reuser selects or provides a code generating function to adapt the framework. A power flow example with a power interchange area is presented.
