Simulation and modeling of Power Converters and Power Conversation Systems

Lecturer: DI Zoran Miletić, AIT 

Starting with a recap of “Control of grid power converters for Photovoltaic applications” the course provides insight in real-time simulation of power converters and implementation of algorithms which have been discussed in theory. Topics covered are methods to develop grid synchronization algorithms based on phase locked loop (PLL) and frequency locked loop (FLL) methods with special treatment of DSOGI (double second order generalized integrator). Futher, typcial grid functions such as Volt-Var, Frequency-Var and Frequency-Watt are presented. 

A methodological basis for the lecture is use of hardware-in-the-loop systems with AIT demonstrator hardware (AIT HIL Controller, and AIT Vindobona power electronics development kit). The development platform is also presented in detail for further use in subsequent courses and staff exchange.
