Release Highlights

• A general-purpose IDAES dynamic power plant model library. It includes not only power plant components but also an example 300 MW (net) subcritical power plant that consists of typical steam boiler and turbine designs for an intermediate-size subcritical coal-fired unit with full-load main steam conditions of 14.4 MPa and 810 K. It can be used to predict plant performance during flexible operation and includes algorithms to estimate the expected time to tube rupture and the number of allowable cycles for load following operations.
• Improved generic properties API to support disjunctive programming solvers.
• New option for including or excluding heat of formation from specific enthalpy calculations.
• Functions for producing Txy diagrams of VLE systems.
• Improved performance of units of measurement features.
• Improved the look, feel, and functionality of the IDAES Flowsheet Visualizer or IFV. The IFV is a web-based user interface (UI) that lets you view and export flowsheets as a process engineering diagram, view and export the "stream table" for the flowsheet, rearrange the flowsheet diagram to your taste and save the arrangement for next time, and dynamically refresh the displayed values to reflect changes in the IDAES model. Major IFV changes in this release:
  • New stream table visualization, including export to CSV
  • Significant visual improvements to diagram and overall look and feel of UI
• New conda install packaging (in addition to pip install) via:

   conda install -c idaes-pse -c conda-forge idaes-pse
  

• Reorganize Caprese code to inherit from Pyomo Block components. This makes solving subproblems and accessing differential/algebraic/input variables easier. Also adds better support for rolling horizon simulations.
