Next generation tools for modelling and analysis of evolving power and energy systems

Electrical energy systems are fast evolving with rapidly increasing complexity, wider acceptance of DC-based technologies, and integration with communication systems and sensors. Sophisticated computer models are essential for operation of electric grids, planning purposes, design and integration of future renewable energy sources and systems. Thousands of engineers in control centers and research facilities around the world are working full-time developing models and conducting studies. Since the models are used by engineers and researchers many times (often iteratively during the design cycle), both the model accuracy and numerical efficiency (simulation time) are very important. Even a fractional increase in simulation speed will result in very significant savings of the engineering time worldwide. However, models of rotating machines and power electronic components are typically the limiting bottle-neck, and the present modeling tools are falling behind of the needs.
