The electrification of transportation hinges on a number of core technologies, such as power electronics and energy storage. In this article, the spotlight is on electric machines (EMs), a term that encompasses all electromechanical energy conversion devices, i.e., motors and generators. Computational electromagnetics, like the finite element method (FEM), play a vital role in a modern EM design workflow. Such methods have been under development for decades, however, with recent advances in computing, they are now mainstream. One of their key features is that they allow us to search a design space with unprecedented accuracy. But perhaps more importantly in today’s rapidly changing landscape, they are accelerating the pace of innovation, reducing prototyping costs and the time it takes to go from concept to product.

Electrical power converters have become indispensable units in modern power systems, with an increasing number of installations, application fields, and ratings. They are used for power conditioning; for controlling network, regulating generation, or load power; for integrating storage systems; and importantly for integrating most renewable energy plants. As a typical example, a modern wind generator will have two ac–dc converters back-to-back connected, facilitating optimal energy extraction from variable speed wind turbines and ensuring that the power plant meets network connection requirements.

The thing that I love about power engineering is that it truly engages with people from all walks of life. We all interact with electricity on a daily basis and the power engineering field offers me the opportunity to play a role in the delivery of this necessity. I am most excited about the rapidly changing face of the power engineering field. This is a time where the industry is being transformed in ways that it has not been shaped in decades.

One of the most remarkable features of power and energy systems pertains to their extremely far-reaching scales, which are unique in the field of engineering. In continental Europe, for example, the synchronous ac power system integrates capitals from Lisbon to Warsaw and from Athens to Copenhagen. Reaching farther out to the north, high-voltage dc (HVdc) links connect to Sweden and the United Kingdom. And as in other regions of the world, those grids are being further developed to integrate more renewables. This only adds to the diversity of technologies in the power grids and contributes to the wide range of timescales involved. Those range from electrothermal interactions in the range of minutes over electromechanical transients within seconds, down to microseconds or even faster for the electromagnetic transients of traveling waves.

What is the most time-consuming part of simulations? In the past, the answer was the simulation itself. So, many experts worked very hard to develop faster simulation algorithms with less consumption of memory. It was also true that many experts worked hard on applying a new computing facility—for instance, a parallel computer—to a specific type of simulation. Those efforts were begun to make the simulation time shorter as much as possible with less memory consumption. However, now, computers are extremely fast with a sufficient amount of memory. For instance, the smartphone in my hand has a gigahertz-clock CPU with eight cores and gigabytes of memory. This is much better than even the mainframe computer shared by many students and even professors when I was a university student about 30 years ago. Laptop and desktop computers and cloud servers today have even better CPUs, memories, and storage. Of course, a faster simulation speed with less consumption of memory is still important since people want to simulate more complex and thus realistic simulation cases with a shorter or similar simulation time. However, this is not the most important aspect anymore, at least for power system simulations.
