Args:
sessions_per_day (List[int]): Number of sessions to sample for each day
of the simulation.
period (int): Length of each time interval. (minutes)
voltage (float): Voltage of the network.
max_battery_power (float): Default maximum charging power for batteries.
max_len (int): Maximum length of a session. (periods) Default None.
battery_params (Dict[str, object]): Dictionary containing parameters for
the EV's battery. Three keys are supported. If none, Battery type
is used with default configuration. Default None.
- 'type' maps to a Battery-like class. (required)
- 'capacity_fn' maps to a function which takes in the the energy
delivered to the car, the length of the session,
the period of the simulation, and the voltage of the
system. It should return a tuple with the capacity of the
battery and the initial charge of the battery both in
A*periods.
- 'kwargs' maps to a dictionary of keyword arguments which will
be based to the Battery constructor.
force_feasible (bool): If True, the requested_energy of each session
will be reduced if it exceeds the amount of energy which could be
delivered at maximum rate during the duration of the charging
session. Default False. Returns: EventQueue: Queue of plugin
events for the samples charging sessions.
