In this tutorial, we will introduce the attendees to high-fidelity and high-speed Hardware-in-the-Loop (HIL) simulations leveraging an FPGA. We will focus on explaining the structure of OPAL-RT’s electrical Hardware Solver (eHS) to solve modelling challenges that require low timesteps beyond the capabilities of running models on the CPU of the real-time simulator. We will then explain the model development workflow to develop the CPU and FPGA models to address various use cases such as the modelling of three-phase inverters and other power electronic converter topologies. Additionally, we will also provide a brief overview of some advanced features and applications of eHS to address accurate modelling and simulation of high switching frequencies for converters such as Dual-Active Bridges and Resonant Converters. Finally, we will provide a detailed walkthrough to show the attendees how an example inverter topology can be modelled and simulated using eHS.

This tutorial aims to clarify the advantages and disadvantages of different HVDC technologies, specifically line-commutated converters (LCC) and voltage source converters (VSC), in the broader context of large-scale power evacuation, HVAC grid support, and renewable power generation and integration. The latest modular multilevel converter topologies for HVDC systems. The interactions of current source and voltage source HVDC links with AC grids will be analysed, including the impacts of the controls and harmonics. AC and DC fault analysis for various HVDC technologies will be discussed, along with an exploration of DC grids, covering theoretical concepts, technology, control, fault management, DC/DC converters, and protection, with a particular emphasis on practical implementation and operational challenges. The talk is supported with simulation on MATLAB/SIMULINK software and practical prototype results.
