Reading Bids Strategy
The ReadingBidsStrategy is an easy way to pre-program time-varying behavior of a satellite model
without relying on any computation logic. The exact bids that should be submitted to the central
market can be defined, for as many or few days as desired. This strategy will continuously iterate
over the bids, looping back to the start of the file when the end is reached.
Example use cases for this strategy include submitting the same set of profile bids every day, or defining fixed weekly behavior that will repeat every 7 days.
Configuration
The ReadingBidsStrategy has various parameters to configure to perform its function. They
are listed below with an explanation.
These attributes are mandatory: the strategy cannot function without this information. All paths are interpreted as relative to the location of the configuration file they are specified in. This is the recommended usage. Alternatively, paths can be given as absolute, although this is discouraged for the sake of reproducibility across different machines.
strategyMust bereading_bidsto tellannularthat this file configures aReadingBidsStrategy.bids_csv_pathThe bids to be repeated should be listed in this csv file. The expected format is:

profile_block_id |

timestamp |
quantity |
acceptance_ratio |
price |
|---|---|---|---|---|---|---|
… |

Note that the earliest value in the timestamp column must match the first timestamp used by
the central market and other bidding strategies. The global start_hour attribute (or local
overwrite of it) is ignored.
Inherited From Global Simulation Settings
rolling_horizon_stepDefines the number of timesteps for the bidding window. Changing this value to anything other than that used for the whole simulation is not recommended, and will likely result in infeasibility issues.
Any other globally shared or defined attributes are ignored by this strategy.
Example
This example assumes the folder structure as suggested in the basic project page:
energy-system-simulation/
├── ...
├── satellite-configurations/
│ ├── repeating-5h-bids.yml
│ └── ...
└── csv_files/
├── repeating-5h-bids.csv
└── ...
The required configuration to add a ReadingBidsStrategy to the coupled simulation is minimal:
strategy: reading_bids
bids_csv_path: ../csv_files/repeating-5h-bids.csv
All behavior is specified in the bids table CSV file. The truncated example below submits a
collection of bids that repeat on a daily basis. It consists of 20 profiles, each for a demand of
75 units of power for 5 consecutive hours. Since all are listed under the same exclusive_group_id
(1), and they are all submitted at ceiling price, exactly one of the profiles will be accepted.
