multiple_hubs¶
Solving energy hub model for n number of hubs with any network of connections wanted between the hubs.
- To run for multiple hubs:
- $ python multiple_hubs.py -n NUMBER OF HUBS
If n (NUMBER OF HUBS) is not inputted the code will not run.
- Naming input excel files:
- file names should start with “hub” followed by increasing numbers starting from 0. The files should be in the ‘network’ folder
- To set the connections between the hubs ( the links):
All the links between the hubs should be set in a separate excel file in the ‘network’ folder. It should be called “network.xlsx”
The default set up is one directional connections. To set bidirectional connections, the connections should be defined per each direction, i.e:
one direction: link 0: start_id: 0 end_id: 1
- bidirectional: link 0: start_id: 0 end_id: 1,
- link 1: start_id: 1 end_id: 0
The link ids should start from 0 and increase by 1. The node ids (start_id and end_id) correspond to hubs numbering in the names of the hubs excel files.
Note: Do not name constraints specific names in the EHubModel class -> will not be able to construct constraints in multiple_hubs

network_constraint
(hub, link_end, link_start)[source]¶ Yields the constraints that allow a network connection between two hubs.
Parameters: - hub – The hub
- link_end – all the links that the hub ends at
- link_start – all the links that the hub start at
Yields: A network energy balanced constraints for each hub
