Thermal Power Simulation#

The ReGWSWUSE simulation for the thermal power sector is analogous to the domestic-specific ReGWSWUSE simulation.

Input Data#

The ReGWSWUSE simulation for the thermal power sector relies on input data for the following variables:

  • \(CU_{tot,tp}\): tp.consumptive_use_tot

  • \(WU_{tot,tp}\): tp.abstraction_tot

  • \(f_{gw,tp}\): tp.fraction_gw_use

  • \(f_{return,gw,tp}\): tp.fraction_return_gw (0 if no input file provided)

Configuration Options#

Currently, there are no specific configuration options in ReGWSWUSE that affect the simulation logic specific to the thermal power sector.

Simulation Logic#

Consumptive Water Use and Abstraction from Groundwater and Surface Water#

For consumptive groundwater use (\(CU_{gw,tp}\)) and surface water use (\(CU_{sw,tp}\)) in the thermal power sector:

\[CU_{gw,tp}(y,id) = CU_{tot,tp}(y,id) * f_{gw,tp}(id)\]
\[CU_{sw,tp}(y,id) = CU_{tot,tp}(y,id) * (1 - f_{gw,tp}(id))\]

For water abstractions from groundwater (\(WU_{gw,liv}\)) and surface water (\(WU_{sw,liv}\)) in the thermal power sector:

\[WU_{gw,liv}(y,id) = WU_{tot,liv}(y,id) * f_{gw,liv}(id)\]
\[WU_{sw,liv}(y,id) = WU_{tot,liv}(y,id) * (1 - f_{gw,liv}(id))\]

Calculation of Return Flows#

Thermal Power-specific return flows are calculated analogously to irrigation and domestic sector return flows. First, the total return flows from thermal power water use (\(RF_{tot,tp}\)) are calculated, followed by the division of these flows into groundwater (\(RF_{gw,tp}\)) and surface water (\(RF_{sw,tp}\)), according to the relative share of return flows to groundwater within total thermal power sector returns (\(f_{return,gw,tp}\)):

\[RF_{tot,tp}(y,id) = WU_{tot,tp}(y,id) - CU_{tot,tp}(y,id)\]
\[RF_{gw,tp}(y,id) = RF_{tot,tp}(y,id) * f_{return,gw,tp}(,id)\]
\[RF_{sw,tp}(y,id) = RF_{tot,tp}(y,id) * (1 - f_{return,gw,tp}(id))\]

Calculation of Net Abstractions#

Net abstractions for groundwater (\(NA_{gw,man}\)) and surface water (\(NA_{sw,man}\)) in the manufacturing sector are calculated similarly:

\[NA_{gw,tp}(y,id) = WU_{gw,tp}(y,id) - RF_{gw,tp}(y,id)\]
\[NA_{sw,tp}(y,id) = WU_{sw,tp}(y,id) - RF_{sw,tp}(y,id)\]
