Thermal Power Library

Modelon’s Thermal Power Library provides a comprehensive modeling, simulation, and optimization framework for thermal power plant operation, including district heating networks.

Ideal for analyzing plant performance and limitations during transient scenarios, Modelon’s Thermal Power Library covers both new and traditional energy sources such as: concentrated solar power, gas, coal, and nuclear powers. The Thermal Power Library can also be used to verify safety requirements and control systems, needed to cope with rapid load changes brought on by increasing use of renewable energy resources.

Modelon’s flexible modular template structure enables efficient and effective modeling at the appropriate fidelity level. With fast and numerically robust models available, users can efficiently simulate and optimize large scale systems. The Thermal Power Library is well suited for large to small enterprises seeking to perform multiple dynamic design behavior studies in the early stages of concept design.

Coupling the Thermal Power Library with Modelon’s OPTIMICA Compiler Toolkit (a Modelica and FMI-based computational platform for systems design), users can utilize a python interface to solve challenging dynamic optimization problems, with use cases such as plant start-up scenarios or district heating production planning.
