Storage

The Storage class contains data related to storage. One Storage instance is given for each storage technology.

Parameters

id (str): Used to represent the storage name.

capex ({region:{year:float}}) - OSeMOSYS CapitalCostStorage. Investment costs of storage additions, defined per unit of storage capacity. Required parameter, must be specified by user.

operating_life ({region:int}) - OSeMOSYS OperationalLifeStorage. Useful lifetime of the storage facility in years. Required parameter, must be specified by user.

minimum_charge ({region:{year:float}}) - OSeMOSYS MinStorageCharge. It sets a lower bound to the amount of energy stored, as a fraction of the maximum, with a number reanging between 0 and 1. The storage facility cannot be emptied below this level. Optional, defaults to 0.

initial_level ({region:float}) - OSeMOSYS StorageLevelStart. Level of storage at the beginning of first modelled year, in units of activity. Optional, defaults to 0.

residual_capacity ({region:{year:float}}) - OSeMOSYS ResidualStorageCapacity. Exogenously defined storage capacities. Optional, defaults to 0.

max_discharge_rate ({region:float}) - OSeMOSYS StorageMaxDischargeRate. Maximum discharging rate for the storage, in units of activity per year. Optional, defaults to None.

max_charge_rate ({region:float}) - OSeMOSYS StorageMaxChargeRate. Maximum charging rate for the storage, in units of activity per year. Optional, defaults to None.

Examples

A simple example of how a storage technology "STO" might be defined is shown below, along with how it can be used to create an instance of the Storage class:

from tz.osemosys.schemas.storage import Storage

basic_storage = dict(
    id="STO",
    capex={"*": {"*": 100}},
    operating_life={"*": 10},
    minimum_charge={"*": {"*": 0}},
    initial_level={"*": 1},
    residual_capacity={"*": {2020: 3, 2021: 2, 2022: 1}},
    max_discharge_rate={"*": 100},
    max_charge_rate={"*": 100},
)
