Storage Dispatch#

HOPP includes a variety of storage dispatch options based on the PowerStorageDispatch class below:

Power Storage Dispatch#

class hopp.simulation.technologies.dispatch.power_storage.power_storage_dispatch.PowerStorageDispatch(pyomo_model, index_set, system_model, financial_model, block_set_name, dispatch_options)#

Bases: Dispatch

Dispatch algorithm for power storage.

Parameters:

  • pyomo_model (ConcreteModel)

  • index_set (Set)

  • block_set_name (str)

__init__(pyomo_model, index_set, system_model, financial_model, block_set_name, dispatch_options)#

Initialize PowerStorageDispatch.

Parameters:

  • pyomo_model (pyomo.ConcreteModel) – Pyomo concrete model.

  • index_set (pyomo.Set) – Indexed set.

  • system_model – System model.

  • financial_model – Financial model.

  • block_set_name (str, optional) – Name of the block set.

  • dispatch_options (dict, optional) – Dispatch options.

dispatch_block_rule(storage)#

Called during Dispatch’s __init__.

Parameters:

storage – Storage instance.

max_gross_profit_objective(hybrid_blocks)#
