Parallel‐in‐time‐and‐space electromagnetic transient simulation of multi‐terminal DC grids with device‐level switch modelling
Abstract The electromagnetic transient (EMT) simulation of multi‐terminal DC (MTDC) grids requires a detailed device‐level modular multilevel converter (MMC) model, which can have thousands of state variables and complex internal structures. The fast device‐level insulated gate bipolar transistor (I...

Abstract The electromagnetic transient (EMT) simulation of multi‐terminal DC (MTDC) grids requires a detailed device‐level modular multilevel converter (MMC) model, which can have thousands of state variables and complex internal structures.

Based on the analysis of the parallel‐in‐time (PiT) implementation of detailed modelled MMCs, this paper proposes a task‐based hybrid PiT algorithm to achieve high parallel efficiency and speed‐up of MMC with device‐level modelling. Moreover, a transmission line model(TLM)‐based parallel‐in‐time‐and‐space (PiT+PiS) method is proposed to connect PiT grids to conventional or other PiT grids and exploit the maximum parallelism. Simulation results show greater than 30× speed‐up and 60% parallel efficiency on a 48 cores computer for the hybrid PiT method in a 201‐level three‐phase MMC test case, and 20× speed‐up in the transient simulation of CIGRÉ B4 DC grid test system for the PiT+PiS method. |
