Full Changelog: v3.3.0...v3.4.0

v3.3.0

• Added long-duration energy storage (LDES) (PR #471)
• Added GenericPlant model (PR #472) which may be used to:
  • simulate grid and battery performance without resimulating generation of other technologies
  • represent the physics-based performance of a generation technology that is not included in HOPP
• Loosened strictness of comparison for wind turbine config checking and added tests
• Loosened strictness of comparison for wind turbine hub-height and wind resource hub-height
• Updated workflow for specifying wind turbine parameters without specifying a turbine name with PySAM.
• Added ability to download wind resource data from WTK-LED for Alaska (PR #461)
• Added ability to download wind resource data from BC-HRRR CONUS 60-minute (NOAA + NREL) for 2015-2023 (PR #474)
• Updated HOPP for pySAM 7.0.0 release (PR #477)
• Bugfix for cycle counting in the minimum operating cost objective function - no longer throws an error
• Bugfix for flicker mismatch; cases with a single Point now correctly work

v3.2.0

• Updates related to PySAM:

  • Updated PySAM version from 4.2.0 to >6.0.0. Main changes noted in PR #425
  • PySAM generation plant defaults have been updated. Current defaults can be found here
  • PySAM SingleOwner financial model update investment-tax credit and depreciation basis calculations to remove financing fees and reserve account funding from basis.
  • PySAM MHKWave update marine energy device cost curves.
  • PySAM Detailed PV update module and inverter libraries, snow module, tracking, losses.

• Wind-focused usability additions that are detailed here

  • Feature add: new wind layout method called basicgrid that makes the most-square layout that has the option to be site-constrained.
  • Updated wind layout methods to classes
  • Bug-fix: grid angle converted from degrees to radians in make_grid_lines() function in wind_layout_tools.py
  • Updated floris initialization to set attributes from floris_config
  • Update: raise errors when using floris if theres a discrepancy between inputs in WindConfig and information in floris_config (such as num_turbines and the floris_config layout, and turbine parameters like rotor diameter and turbine rating.)
  • Integrated wind layout functionality when using floris
  • Updated wind layout parameters.
  • Minor clean up to floris.py - removed unnecessary data exportation and fixed bug in value()

• Integrated turbine-models library. For further details see here

  • Wind turbines from the turbine-models library can now be simulated by specifying the turbine name. This feature is compatible with floris and PySAM WindPower simulations.
  • Added wind turbine power-curve tools to estimate thrust coefficient, power coefficient, and power-curve.

• Added two distributed wind-hybrid examples that highlight the turbine-models library package and other recent features for wind system modeling and simulations. These examples are:

  • examples/08-distributed-residential-example.ipynb
  • examples/09-distributed-residential-midsize.ipynb

• Added tidal models

  • Added TidalResource to load tidal resource data for simulating tidal energy.
  • Added MHKTidalPlant to simulate tidal energy.
  • Add tidal energy to HybridSimulation.
  • Add tidal energy to dispatch.

• Other feature additions:

  • Added option and functionality to load wind and solar resource data from NSRDB and Wind Toolkit data files if user-specified.
  • Added ability and option to initialize site_info with preloaded and formatted wind and solar resource data
  • Feature add: added alternative method to defining site boundary.
  • Feature add: added function to adjust air density based on site elevation
  • Added weighted average wind resource parsing method option when using floris.
  • Update deprecated methods in wave_resource.py

• Bug fixes:

  • Remove erroneous 100 multiples for percentages and add clarifying parentheses for correct 100 multiples for percentages.
  • Fixed a bug in site_info that set resource year to 2012 even if otherwise specified.
  • Bug fix in load following heuristic method: only using beginning of variable load signals

v3.1.1 Release

• Enhanced PV plant functionality: added tilting solar panel support, improved system design handling, and refined tilt angle calculations.
• Integrated ProFAST into the custom financial model for LCOE and other financial calculations; updated CI and documentation accordingly.
• Adjusted battery financials to use discharged energy for levelized cost calculations.
• Improved testing and fixed various bugs, including logging errors, financial model instantiation, and configuration handling.
• Removes unnecessary packages from the dependency stack.
• Documentation moved to a jupyter-book style and build process.

v3.1

• Added Cambium and GREET integration for LCA analysis
• Updated examples throughout
• Removed package dependencies to streamline installation on Windows
