Software for Simulation of Power Plant Processes. Part B - Program Description and Application

Modelling of energy systems has been increasingly more important. In particular the dynamic behaviour is critical when operating the systems closer to the limits (either of the process, the materials, the emissions or the economics, etc.). This enforces strong requirements on both the models and their numerical solution with respect to both accuracy and efficiency. In this paper we give a survey on simulation of energy systems, from models and modelling, over numerical methods to implementational techniques. The paper is the second part of two papers covering important aspects of the different phases of modelling in general and modelling of an (energy) system. Part A, also gives a short introduction to robust numerical methods which it is strongly recommended to use. In this part, Part B, we present a survey of available, commercial and university simulators, a few important aspects of the implementation of the energy system simulator DNA and a short tricky example showing that too simple models may result in unexpected problems.
