GridPath - GridPath v0.8.0

Changes since v0.7.3:

  • Enhancement (breaking change): Update handling of solver status (f8bfaeb)
    To reimport preexisting results, the solver_status.txt file would have to be renamed termination_condition.txt.
  • Bugfix: Fix solver query in queue manager (698f448)
  • Bugfix: Fix queue manager when no solver options specified (e96e420)
  • Feature (breaking change): Implement charge/discharge capacity multipliers (b7297c7)
    To upgrade from 0.7.3, do the following:
    1. Add the columns 'charging_capacity_multiplier' and 'discharging_capacity_multiplier' in your project_operational_chars_scenario_id CSVs after the 'discharging_efficiency' column. These can be left blank or set to 1 to replicate the treatment in 0.7.3.
    2. Update the database schema (add two FLOAT columns, charging_capacity_multiplier and discharging_capacity_multiplier after the discharging_efficiency column in inputs_project_operational_chars. Query below:
