Data logger

class fleetrl.utils.data_logger.data_logger.DataLogger(episode_length)

Bases: object

Logs data to allow for postprocessing, graphs, etc. The log is a dataframe, where each row can be a float or an array. Deepcopy to avoid risk of mutability (logs pointing back to changing variables)

log_data(time, obs, action, reward, cashflow, penalty, grid, soc_v, degradation, charge_log, soh)

While the env object is the same, the episode counter will recognise different episodes. A dict is created with the required values, and then appended to the log dataframe

Parameters:

• time (Timestamp) – Current timestamp

• obs (ndarray) – Observation array

• action (ndarray) – Action array

• reward (float) – Reward float

• cashflow (float) – in EUR

• penalty (float) – penalty float

• grid (float) – Grid connection in kW

• soc_v (float) – Amount of SOC violated in # of batteries

• degradation (float) – Degradation in that timestep

• charge_log (ndarray) – How much energy flowed into the batteries in kWh

• soh (ndarray) – Current SoH, array

Returns:

None
