offgridders - [Offgridders V4.4] - Bug fixes

[Offgridders V4.4] - 2020-07-09

Added

• Error message if parameter evaluation_perspective is not chosen correctly (#97)
• Warning message if fuel_price_change_annual != 0, as calculation may be faulty (#97)

Changed

• Added parameter consumption_fuel_annual_kWh to simulation outputs (#97)
• Input template file so that it runs MCA and gives options of evaluation_perspective (#97)
• If fuel_price_change_annual == 0, function present_value_changing_fuel_price is not executed and returns fuel price (#97)
• Order of cost results in simulation outputs, as first_investment_cost, operation_mantainance_expenditures as these are not to be added to costs, expenditures and revenues to calculate the NPC (#97)
• Formula calculating the residual value of an asset. Now, the sales revenue is translated into a present value:
  linear_depreciation_last_investment = last_investment / lifetime and capex = capex - linear_depreciation_last_investment * (number_of_investments * lifetime - project_life) / (1 + wacc) ** (project_life) (#97)
  )`

Removed

• Removed unused function call in G2a (genset_oem_minload) (#97)

Fixed

• Miscalculation of total_demand_supplied_annual_kWh due to wrong evaluation_perspective on tab case_definitions (#97)
• Function call of present_value_changing_fuel_price (#97)
• Typo: Replace operation_mantainance_expenditures by operation_maintenance_expenditures (#97)

offgridders - [Offgridders V4.2] - Additional outputs

Added

• total_excess_annual_kWh to list of output parameters. Calculation: total_excess_annual_kWh = total_excess_ac_annual_kWh + total_excess_dc_annual (#73)
• Optional parameters and their default values fuel_co2_emission_factor (2.68 kgCO2eq/l diesel) and maingrid_co2_emission_factor (0.9 kgCO2eq/kWh) to input template, sheet input_constant and module B (#77)
• Calculation of C02 emissions and new output value: co2_emissions_kgCO2eq. It is based on the kWh consumption from the national grid (before transfromer station losses) and diesel consumption (#77)

Fixed

• Typo when calling for the inverter capacity (capacity_inverter_dc_ac_kW and not capacity_inverter_kW), (#75)
• Typo for unit of maingrid_extension_lifetime (a)

• A0 to call MCA
• B to read data from xlsx for MCA
• C: Extend set of parameters that are an output of simulation by "total_pv_generation_kWh", "total_wind_generation_kWh", "total_genset_generation_kWh"
