Not able to start a generator which states is off

[camiloromers]

Hello,

I am not able to start a generator which is state at time T is 0MW or off. In the following script, I tried to start gen at node 23 increasing its power but I got an exception:

Grid2OpException AmbiguousAction InvalidRedispatching InvalidRedispatching('Impossible to dispatched a turned off generator')

import numpy as np
import grid2op

env = grid2op.make('wcci_test')

env.chronics_handler.tell_id(183)
print(env.chronics_handler.get_name())

# Set min up/down time = 0
env.gen_min_downtime = np.zeros(shape=env.gen_min_downtime.shape)
env.gen_min_uptime = np.zeros(shape=env.gen_min_uptime.shape)
env.gen_uptime = np.zeros(shape=env.gen_uptime.shape)
env.gen_downtime = np.zeros(shape=env.gen_downtime.shape)

# Run Game from specific ts
t0, tf = 7163, 7168

# Run donothing and trying to start a thermal unit
obs = env.reset()
env.fast_forward_chronics(t0)
for i in range(tf-t0+1):
    if t0+i == 7165:
        action = {'redispatch': [(13, +2.5)]} # Start a thermal unit 18 at node 23
    else:
        action = {} # Do nothing
    obs, reward, done, info = env.step(env.action_space(action))
    print ('Thermal MW: {:2f} MW at ts {:1d}'.format(obs.prod_p[13], t0+i))
    print (info['exception'])

EDIT (BD): I updated the above script to work

This was not a bug but rather the normal behaviour. Indeed, as you saw, it's clearly stipulated that today you cannot redispatch a turned off generator.

In the next realese we'll see how to best address this by giving the possibility to either:

• forbid the dispatch on the turned off generator (which is totally irrealistic btw)
• allow it for simplicity (which would make the game easier, not to mention the generation of the chronics...)

Thanks for raising this issue
