pywr.nodes.AnnualVirtualStorage

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

A virtual storage which resets annually, useful for licences

See documentation for pywr.core.VirtualStorage.

Parameters:

reset_day: int

The day of the month (0-31) to reset the volume to the initial value.

reset_month: int

The month of the year (0-12) to reset the volume to the initial value.

reset_to_initial_volume: bool

Reset the volume to the initial volume instead of maximum volume each year (default is False).
