Abstract:
This paper describes the development of a simulation program called CARNOT (Conventional And Renewable eNergy Optimization Toolbox) for the environment MATLAB Simulink. The program combines the easy-to-use graphical environment of Simulink ? with the powerful algorithms and differential equation solvers of MATLAB ? for the application of solar thermal system simulation. Advantages to commercially available programs are the variable time steps, which enable long time simulation with an adequate simulation time. Furthermore the time step can decrease to sub second range, which is a key feature for short time resolution that is important in highly dynamic systems, e.g. for controller design. The concept of the library CARNOT is similar to the Simulink ? standard library. The models are organized in so called subsets that contain the components of conventional and renewable heating systems. The program performs simultaneous calculation of heat transfer and hydraulics. New systems configurations can be created entirely by mouse operations, just drag-and-drop the respective blocks from the library. Interconnection of the blocks is done by lines that represent vectors of the physical properties. The included models can be easily extend to own components, which can be integrated as graphical Simulink ? models (subsystems) or in C-, Fortran-or MATLAB ? M-scripting language. In the same way completely new models of components can be included.
