Towards identifying an approach for consistency checks to smart grid descriptions

Smart grids are developing from the increasing integration of intelligent systems and components into power supply systems. These various systems and components within smart grids have to be connected via information and communication technologies (ICT) to allow a smooth data exchange between systems. Therefore, systems' interfaces should be defined to manage systems and their components. Smart grids are systems of systems. Due to the complexity and high number of interfaces, smart grids have a comprehensive requirements management, and hence, smart grids' specifications are also complex. For example, the integration of distributed energy resources and their power meters as well as the integration of electrical vehicles and their charging station are part of smart grids and have to be planned through a complete and consistent requirements specification for a smooth process. Due to the large number of requirements and different stakeholders who create these requirements, consistency checks should support the specification process for smart grids to receive a proper operation between systems. This paper gives a problem statement about inconsistent requirements and motivates the usage of consistency checks in requirements' specifications of complex systems, such as smart grids and electric mobility. Furthermore, it gives an overview on future work how consistency checks can be realized and knowing techniques can be reused.
