class Parameters:
    """
    Main classes representing the parameters of the game. The main parameters are described bellow.

    Note that changing the values of these parameters might not be enough. If these _parameters are not used in the
    :class:`grid2op.Rules.RulesChecker`, then modifying them will have no impact at all.

    Attributes
    ----------
    NO_OVERFLOW_DISCONNECTION: ``bool``
        If set to ``True`` then the :class:`grid2op.Environment.Environment` will **NOT** disconnect powerline above their
        thermal limit. Default is ``False``, meaning that grid2op will disconnect powerlines above their limits
        for too long or for "too much".

    NB_TIMESTEP_OVERFLOW_ALLOWED: ``int``
        Number of timesteps for which a soft overflow is allowed, default 2. This means that a powerline will be
        disconnected (if :attr:`.NO_OVERFLOW_DISCONNECTION` is set to ``False``) after 2 time steps above its thermal
        limit. This is called a "soft overflow".

    NB_TIMESTEP_RECONNECTION: ``int``
        Number of timesteps a powerline disconnected for security motives (for example due to
        :attr:`.NB_TIMESTEP_POWERFLOW_ALLOWED` or :attr:`.HARD_OVERFLOW_THRESHOLD`) will remain disconnected.
        It's set to 10 timestep by default.

    NB_TIMESTEP_COOLDOWN_LINE: ``int``
        When someone acts on a powerline by changing its status (connected / disconnected) this number indicates
        how many timesteps the :class:`grid2op.Agent.BaseAgent` has to wait before being able to modify this status
        again.
        For examle, if this is 1, this means that an BaseAgent can act on status of a powerline 1 out of 2 time step (1
        time step it acts, another one it cools down, and the next one it can act again). Having it at 0 it equivalent
        to deactivate this feature (default).

    NB_TIMESTEP_COOLDOWN_SUB: ``int``
        When someone changes the topology of a substations, this number indicates how many timesteps the
        :class:`grid2op.Agent.BaseAgent` has to wait before being able to modify the topology on this same substation. It
        has the same behaviour as :attr:`Parameters.NB_TIMESTEP_LINE_STATUS_REMODIF`. To deactivate this feature,
        put it at 0 (default).

    HARD_OVERFLOW_THRESHOLD: ``float``
        If a the powerflow on a line is above HARD_OVERFLOW_THRESHOLD * thermal limit (and
        :attr:`Parameters.NO_OVERFLOW_DISCONNECTION` is set to ``False``) then it is automatically disconnected,
        regardless of
        the number of timesteps it is on overflow). This is called a "hard overflow". This is expressed in relative
        value of the thermal limits, for example, if for a powerline the `thermal_limit` is 150 and the
        HARD_OVERFLOW_THRESHOLD is 2.0, then if the flow on the powerline reaches 2 * 150 = 300.0 the powerline
        the powerline is automatically disconnected.

    SOFT_OVERFLOW_THRESHOLD: ``float``
        .. versionadded:: 1.9.3
        
        Threshold above which delayed protection are triggered. A line with its current bellow `SOFT_OVERFLOW_THRESHOLD * thermal_limit`
        then nothing happens. If it's above the delay start. And if it's above `SOFT_OVERFLOW_THRESHOLD * thermal_limit`
        for more than :attr:`NB_TIMESTEP_OVERFLOW_ALLOWED` consecutive steps.
    
    ENV_DC: ``bool``
        Whether or not making the simulations of the environment in the "direct current" approximation. This can be
        usefull for early training of agent, as this mode is much faster to compute than the corresponding
        "alternative current" powerflow. It is also less precise. The default is ``False``

    FORECAST_DC: ``bool``
        DEPRECATED. Please use the "change_forecast_param" function of the environment
        Whether to use the direct current approximation in the :func:`grid2op.Observation.BaseObservation.simulate`
        method. Default is ``False``. Setting :attr:`FORECAST_DC` to `True` can speed up the computation of the
        `simulate` function, but will make the results less accurate.

    MAX_SUB_CHANGED: ``int``
        Maximum number of substations that can be reconfigured between two consecutive timesteps by an
        :class:`grid2op.Agent.BaseAgent`. Default value is 1.

    MAX_LINE_STATUS_CHANGED: ``int``
        Maximum number of powerlines statuses that can be changed between two consecutive timesteps by an
        :class:`grid2op.Agent.BaseAgent`. Default value is 1.

    IGNORE_MIN_UP_DOWN_TIME: ``bool``
        Whether or not to ignore the attributes `gen_min_uptime` and `gen_min_downtime`. Basically setting this
        parameter to ``True``

    LIMIT_INFEASIBLE_CURTAILMENT_STORAGE_ACTION: ``bool``
        If set to ``True`` (NOT the default) the environment will automatically limit the curtailment / storage actions that otherwise
        would lead to infeasible state.

        For example the maximum ramp up of generator at a given step is 100 MW / step (
        ie you can increase the production of these generators of maximum 100 MW at this step) but if you cumul the storage
        action and the curtailment action, you ask + 110 MW at this step (for example you curtail 100MW of renewables).

        In this example, if param.LIMIT_INFEASIBLE_CURTAILMENT_ACTION is ``False`` (default) this is a game over. If it's ``True``
        then the curtailment action is limited so that it does not exceed 100 MW.

        Setting it to ``True`` might help the learning of agent using redispatching.
        
        If you want a similar behaviour, when you don't have access to the parameters of the environment, you can
        have a look at :func:`grid2op.Aciton.BaseAction.limit_curtail_storage`. 
        
        .. note::
            This argument and the :func:`grid2op.Action.BaseAction.limit_curtail_storage` have the same objective:
            prevent an agent to do some curtailment too strong for the grid.
            
            When using this parameter, the environment will do it knowing exactly what will happen next (
                its a bit "cheating")  and limit exactly the action to exactly right amount.
            
            Using :func:`grid2op.Aciton.BaseAction.limit_curtail_storage` is always feasible, but less precise.

    INIT_STORAGE_CAPACITY: ``float``
        Between 0. and 1. Specify, at the beginning of each episode, what is the storage capacity of each storage unit.
        The storage capacity will be expressed as fraction of storage_Emax. For example, if `INIT_STORAGE_CAPACITY` is
        0.5 then at the beginning of every episode, all storage unit will have a storage capacity of
        0.5 * `storage_Emax`. By default: `0.5`

    ACTIVATE_STORAGE_LOSS: ``bool``
        You can set it to ``False`` to not take into account the loss in the storage units.
        This deactivates the "loss amount per time step" (`storage_loss`) and has also the effect to set
        to do **as if** the
        storage units were perfect (as if `storage_charging_efficiency=1.` and `storage_discharging_efficiency=1.`.

        **NB** it does **as if** it were the case. But the parameters `storage_loss`, `storage_charging_efficiency`
        and storage_discharging_efficiency` are not affected by this.

        Default: ``True``

    ALARM_BEST_TIME: ``int``
        Number of step for which it's best to send an alarm BEFORE a game over

    ALARM_WINDOW_SIZE: ``int``
        Number of steps for which it's worth it to give an alarm (if an alarm is send outside of the window
        `[ALARM_BEST_TIME - ALARM_WINDOW_SIZE, ALARM_BEST_TIME + ALARM_WINDOW_SIZE]` then it does not grant anything

    ALERT_TIME_WINDOW : ``int``
        Number of steps for which it's worth it to give an alert after an attack. If the alert is sent before, the assistant
        score doesn't take into account that an alert is raised. 

    MAX_SIMULATE_PER_STEP: ``int``
        Maximum number of calls to `obs.simuate(...)` allowed per step (reset each "env.step(...)"). Defaults to -1 meaning "as much as you want".

    MAX_SIMULATE_PER_EPISODE: ``int``
        Maximum number of calls to `obs.simuate(...)` allowed per episode (reset each "env.simulate(...)"). Defaults to -1 meaning "as much as you want".
