enex_analysis.ashpb_pv_ess

ASHPB Scenario: Heat Pump driven by PV + ESS with Grid/Dump integration.

Energy routing (all logic lives here, subsystems are pure physics):

  1. PV generation → pv.calc_performance()

  2. DC routing: - PV surplus → ess.charge(); leftover → dump - PV deficit → ess.discharge(); leftover → grid import

  3. Inverter conversion loss applied to DC supply

  4. Grid import covers any remaining AC shortfall

Note

Theoretical overview, system boundaries, and orchestration logic for hybrid systems are detailed in Hybrid Heat Pump Systems.

Classes

ASHPB_PV_ESS(*, pv[, ess, eta_inv, T_inv_K])

ASHPB scenario where the heat pump is supplied by PV + ESS + Grid.
class enex_analysis.ashpb_pv_ess.ASHPB_PV_ESS(*, pv, ess=None, eta_inv=0.95, T_inv_K=313.15, **kwargs)[source]

ASHPB scenario where the heat pump is supplied by PV + ESS + Grid.

The PV/ESS routing is resolved synchronously inside _augment_results after the HP compressor load is known. No 1-step lag: the PV energy is allocated to the exact HP load produced in the same timestep.

Parameters:

  • pv (PhotovoltaicSystem) – Pure-physics PV + charge-controller model.

  • ess (EnergyStorageSystem) – Pure-physics battery model with charge() / discharge().

  • eta_inv (float) – Inverter DC→AC efficiency [–].

  • T_inv_K (float) – Inverter temperature for entropy calculation [K].

  • **kwargs – Forwarded to AirSourceHeatPumpBoiler.
