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

随着复杂性的迅速增加，基于直流技术的广泛接受以及与通信系统和传感器的集成，电能系统正在快速发展。复杂的计算机模型对于电网的运行、规划目的、未来可再生能源和系统的设计和集成至关重要。世界各地的控制中心和研究机构的数千名工程师正在全职开发模型和进行研究。由于模型被工程师和研究人员多次使用（通常在设计周期内迭代使用），因此模型的精度和数值效率（仿真时间）都非常重要。即使是模拟速度的一小部分提高，也会在全球范围内节省大量的工程时间。然而，旋转机械和电力电子元件的模型是典型的限制瓶颈，目前的建模工具落后于需求。

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.
