LENA Grid Control Center for Dynamic Security Analysis
Only a few universities and research institutions in Germany own a grid control center and even fewer have a simulative test environment for the evaluation of transient system stability.
The importance of such a system for research institutions is further enhanced by the transformation of the energy supply system in Germany and Europe. In this context, innovative solutions are needed to reliably assess and guarantee system stability even with a lower share of conventional generation plants. The system proposed here provides the basis for performing such analyses in a practical environment, thus directly developing methods and indications that will continue to enable and simplify the work for control center personnel in the future.
The elimination of conventional inertia and the resulting issues regarding the transient stability of the electrical grid are of great importance for the successful completion of the energy transition. Therefore, these topics are also gaining importance within the energy research program of the BMWK, which means that the project presented here strengthens the eligibility of OVGU within funding programs at the federal level.
Furthermore, transient stability is not only a local, but a European issue. Inter area oscillations in the European interconnected grid always affect several control areas or countries. Thus, the project creates an important prerequisite for future cooperation with other research institutions and grid operators in other control areas within the framework of EU projects.
The project will create a system environment to which further algorithms and methods can be added on a modular basis. This ensures that the environment can also be used regularly in future research projects. In addition, the system environment ensures a sustainable and future-oriented education of students, since the bachelor or master theses, which are written in cooperation with this environment, address topics relevant for the future system operation of the electrical grid.
Within the framework of various projects, the OVGU already cooperates with grid operators and manufacturers of control system software. The possibilities for cooperation will be expanded by the project described here to include further research topics. In particular, increased cooperation with transmission system operators can be sought through the implementation of this project.
