A model-based approach for the specification of a virtual power plant operating in open context
Vasileios Koutsoumpas · 2015
Nowadays, it's widely accepted that the paradigm of closed context systems has altered. As software systems in combination with physical systems, termed Cyber Physical Systems (CPSs) evolve to more and more complex structures to meet the continuously increasing complexity of requirements, they are faced with a variety of challenges. Those systems have to operate in an open context, meaning that the system boundary between the system and the environment changes over time. Furthermore, the operating system has to adapt its behavior to the observed environmental changes. Hence, there is a high need for the establishment of a seamless modeling framework which fosters the modeling of systems operating in open context. In this paper: 1) we explore how a modeling theory based on fuzzy logic allows for a formal specification of such systems 2) we embed the modeling theory to the SPES development method established within the German research project SPES by showing the compositionality of our approach 3) we illustrate on a show case how the approach can be applied exemplary for modeling the behavior of a Virtual Power Plant (VPP).
