TOP-Energy 3.4.0: New components & improved handling

TOP-Energy 3.4.0, a powerful update to the optimization software for energy systems, is now available. The release brings new components and components enhanced with new functions, including solutions to year-round coupling modeling problems, and more convenient, faster handling—for even more precise, sustainable, and economical energy system analyses.

Thanks in particular to a new two-stage optimization algorithm, issues such as seasonal energy storage or limiting CO₂ emissions can now be modeled easily with just a few clicks. This enhancement also means that power costs can now be taken into account in all tariffs during the optimization calculation.

Overview of new features

Additional components for realistic energy models

  • Stratified storage for improved simulation of heat cycles with different temperature levels
  • CO2 limitation for specifying the total annual amount of greenhouse gas
  • Steam compressor for modeling additional flexibility in steam systems
  • Seven new control components for additional constraints in structural optimization and for year-round coupling
  • Familiar components with new functions Water, heat, cooling, steam, and fuel storage tanks can be declared as seasonal storage tanks to activate two-stage optimization
  • In addition to the now possible limitation of power costs, tariffs also have an extension of the graduated prices to obtain monthly, quarterly, and annual billing

Software adjustments

  • New two-stage solution algorithm for complex year-round couplings
  • Performance improvements – you will appreciate the difference, especially when using many time series
  • The component database now also offers data from the technology catalog of the Competence Center for Municipal Heat Transition (KWW)
  • Parameter studies sometimes take longer than originally anticipated. They can now be paused and resumed at any time
  • The simulator ribbon has been expanded and redesigned
  • Gurobi & PVGIS have been updated to the latest versions
  • Bug fixes for a more error-free application
