Modeling, Operation, and Analysis of DC Grids presents a unified vision of direct current grids with their core analysis techniques, uniting power electronics, power systems, and multiple scales of applications. Part one presents high power applications such as HVDC transmission for wind energy, faults and protections in HVDC lines, stability analysis and inertia emulation. The second part addresses current applications in low voltage such as microgrids, power trains and aircraft applications. All chapters are self-contained with numerical and experimental analysis.
Graduate students and 1st year PhD students (and related early career researchers) from control engineering, power electronics, power systems engineering. Early career researchers investigating power systems analysis, analysis of DC grids, stability, HVDC transmission and / or microgrids. Engineers who are used to AC systems and to understand the operation of DC grids
