A component based approach to power system application development

This paper addresses issues of reusability of component models. Once a component model is designed, implemented and tested, it should be possible to use it as many times as necessary for a variety of purposes. The main idea of this paper is to introduce a new way for build-ing flexible power system applications. In order to obtain code reusability a “general” non-linear equation handler and solver is implemented. The general-purpose solver does not need to know in advance what kind of problem is going to be solved. Instead, the solver is based on symbolic model handling and evaluation. In order to use the model, each specific application of interest has a converter that trans-forms input data to the realm of the general purpose solver. Both the application-specific converter and the general purpose equation handler and solver are designed as com-ponents. Thus, there is no need to change, or to recode the solver each time when new specific problem of interest arises. It is only necessary to create a new “converter.” The result is that the complete development process is less error prone. In addition to describing code reusability, this paper also presents a unique way of collecting input data and model descriptions that make ii possible to reuse sym-bolic models in an effective manner.
