In this paper mathematical models of steam turbines used in mixed integer nonlinear programming (MINLP) are improved to enable more realistic results from the optimisation and more robust and reliable op-timisation models. The modern advanced power plant is in many respects very well optimised, which means that the focus today is on marginal improvements to(More)
In this work, a methodology for building multi-period optimisation model of steam turbine network is presented. The optimi-sation model can estimate and evaluate the effect of changes to the thermal energy demand of processes. The subject is divided into two parts. In Part I, a method for finding regression models for steam turbine networks using a(More)
The integration of different energy systems, e.g., industrial and municipal, is potentially important for the efficient utilization of energy. It is important that the tools for analysing this type of integration can handle the energy systems on different levels, e.g., regional, site, plant and process levels. In this work, a framework for investigating the(More)
