pump_cost#
module wntr.metrics.economic
- pump_cost(energy, wn)[source]#
Compute the pump cost over time.
Energy cost is defined in
wn.options.energy.global_price. Pump energy price and price patterns are currently not supported.wn.options.energy.global_price = 3.61e-8 # $/J; equal to $0.13/kW-h
- Parameters:
energy (pandas DataFrame) – A pandas DataFrame containing pump energy (J), computed from
wntr.metrics.pump_energy(index = times, columns = pump names).wn (wntr WaterNetworkModel) – Water network model. The water network model is needed to define pump enery prices and patterns.
- Return type:
A DataFrame that contains pump cost in $ (index = times, columns = pump names).
