Virtual-oscillator based control of inverters in power grids



Catalin Arghir, Florian Dörfler

In the context of inverter-based power grids we are investigating a control problem formulation starting from average-switch models of 3-phase AC/DC inverters. By neglecting the switching harmonics, the system is easier to handle, retains energy conservation properties and can be seen as passive. In this setting synchronous machines can be emulated or model-matched giving rise to a consensus-type problem around the DC-link voltage of the inverters. Your task will be to focus on the nonlinear system properties and find control laws that yield useful practical applications either for a single inverter or a network of inverters. Ideally you have some interest in low-level control of power electronics and are familiar with standard nonlinear control tools. We are mainly interested in theoretical aspects but may also pursue simulation studies and even hardware implementation depending on the student's background.
