Review of state-of-the-art solver solutions for HIL simulation of power systems, power electronic and motor drives

In this paper, we review state-of-the-art solvers and techniques applicable to HIL simulation of power systems, power electronics and motor drives. These methods can be distinguished by the applications as well as the computational hardware engines used. Industrially speaking, there are two main types of hardware used today to make HIL: multi-core CPUs and FPGAs. Other promising technologies like, GPU (and similar approaches such as Intel 100 cores `Xeon phi´ coprocessors), are also possible and rather similar to multi-CPU approach but not discussed in this paper.
