Storage
Objects for representing electricity storage units and aggregates within the grid.
EnergyStorage
An object representing the aggregate storage capaciticies of a single kind of storage.
name
property
Return the storage aggregate's textual identifier.
output
property
Return the current power output in MW. Negative if charging, positive if discharging.
remaining_capacity
property
Return the amount of remaining energy storage capacity in MWh.
__init__(name, nominal, max_storage, efficiency=1.0)
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
name
|
str
|
Short textual identifier of the storage aggregate, e.g. "p2g" or "pumped". |
required |
nominal
|
Power
|
Nominal (installed) capacity of the storage unit in MW. |
