One can define an energy system as a system that converts one or more energy fluxes into other energy fluxes of a different kind. This definition may describe a relatively small system – for instance a power plant, a chemical plant, the heating and cooling system of a single-family house – as well as one covering larger energy needs – as for instance the needs of a city, of a country, or even of a continent. As energy systems are developed through the centuries, the way we structure these systems goes through changes affected by contextual conditions. Recently, concerns about the availability of traditional fossil energy sources and their environmental effects are revolutionizing the way energy systems are planned, designed, and operated.

Modern energy systems are expected to be multi-modal and incorporate electrical, gas, and heat networks – to achieve maximum usage of every form of energy available – and to include storage capacity. The distributed nature of new resources (generation and storage) and the partici- pation of loads in energy management require fast, reactive control, and protection. In this context the monitoring and control of modern energy systems are expected to be characterized by distribution of functions. At the same time – to ensure optimal coordination – a large use of communication media is envisioned. Interactions between continuous dynamics and dis- crete events are becoming more relevant due to the increasing number of controllable devices (e.g., power electronic converters in the electrical grids) and the use of networked control schemes. Energy systems, furthermore, are increasingly driven by market competition. Because of these characteristics and because of human involvement, modern energy systems can therefore be classified as complex and concerns about emerging behaviors might be raised.

The complexity of such systems poses significant challenges on how these systems are planned, designed, and operated and numerical simulation it is a fundamental tool to tackle those challenges.

In the seminar we will review recent development in simulation methods for energy systems.
