pywr.nodes.AggregatedStorage

class pywr.nodes.AggregatedStorage(*args, **kwargs)

An aggregated sum of other Storage nodes

This object should behave like Storage by returning current flow, volume and current_pc. However this object can not be connected to others within the network.

Parameters:

model - `Model` instance

name - str

storage_nodes - list or iterable of `Storage` objects

The Storage objects which to return the sum total of

Notes

This node can not be connected to other nodes in the network.

__init__(model, name, storage_nodes, **kwargs)

Methods
