A Gray-Box Approach for Decentralized Grid-Equivalent Model Identification
Sanjay Chandrasekaran, Florian Dörfler, Silvia Mastellone
We propose a decentralized, frequency-domain identification algorithm that estimates the grid-equivalent model using local measurements from the perspective of each converter. Sinc…
Resilient AFE Drive Control using Neural Networks with Tracking Guarantees
Nicolas Kirsch, Catalin Arghir, Silvia Mastellone +1
Industrial installations across several sectors have seen a dramatic increase in productivity, accuracy and efficiency over the last decade due to expanded utilization of medium vo…
Transferring the driveshaft inertia to the grid via the DC-link in MV drive systems
Catalin Arghir, Pieder Jörg, Silvia Mastellone
This paper investigates a control approach that renders the driveshaft inertia completely available on the grid side and enhances the fault ride-through behavior of medium-voltage…
Reactive power flow optimization in AC drive systems
Sanjay Chandrasekaran, Catalin Arghir, Pieder Joerg +2
This paper explores a limit avoidance approach in the case of input (modulation) and output (current) constraints with the aim of enhancing system availability of AC drives. Drawin…
