Circuit theory is a systematic approach of modeling and analyzing electronic circuits and electrical systems and, thus, constitutes a key field of electrical engineering. At its core lies the representation of the system of interest as an interconnection of components using a network graph, which yields an appropriate mathematical model for the analysis and simulation of electrical systems. Circuit theory is a foundation for the design and operation of many different kinds of systems, with applications ranging from communication to power systems.

Circuit theory is used in the following fields of research at our institute:

• Optimization in Power Systems
