pywr - v1.15.3

Bug Fixes

  • Fix bug where constraints are not applied between VirtualStorage and some complex node types (e.g PiecewiseLink and AggregatedNode).

See issue #1001 to see details and track progress. (#1002)

Bug Fixes

  • Fix bug with AggregatedParameter.remove() and AggregatedIndexParameter.remove() methods using the wrong method internally. (#997)

pywr - v1.15.1

Bug Fixes

  • Fix AnnualTotalFlowRecorder's accounting of flow when a timestep ends in the following year. (#992)
  • Fix divide by zero errors in NumpyArrayNodeSuppliedRatioRecorder and NumpyArrayNodeCurtailmentRatioRecorder when the max flow of the parameter they monitor returned zero. (#993)
  • Fix the load method of FlowDurationCurveDeviationRecorder to handle scenario data correctly. (#989)

- Python
Published by jetuk over 4 years ago

pywr - v1.15.0

New Features

  • Performance improvements for the GLPK solvers. Several new options have been added to the GLPK solvers that reduce the number of linear programme updates required each time-step. These options are currently off by default, but can be enabled by either passing keyword arguments to the solver instances or via environment variables. (#912, #983, #985)
    • Update constant and fixed flows only once during reset (PYWR_SOLVER_GLPK_FIXED_FLOWS_ONCE=True)
    • Update constant and fixed costs only once during reset (PYWR_SOLVER_GLPK_FIXED_COSTS_ONCE=True)
    • Update constant and fixed aggregated node factors only once during reset (PYWR_SOLVER_GLPK_FIXED_FACTORS_ONCE=True)
  • Improve memory usage in DataFrameParameter when running a subset of the defined scenarios. The parameter now only retains the data for the subset of scenarios required for the simulation instead of all scenarios. (#981)
  • Update MonthlyProfileParameter and RbfProfileParameter to allow variable lower and upper bounds to be defined. (#986)

Bug Fixes

  • Fix use of deprecated np.int and np.float types. (#982)
