Curtailed VRE production

[Alexander Priven]

Hi all,

I am running a multi year optimization model with multiple generators using thermal and VRE energy along with batteries. 

I am examining the effect that adding new battery capacity has on VRE generation, specifically how decreasing battery capacity curtails VRE production.

I was wondering if pypsa is able to produce an output which shows how much generation has been curtailed for each investment year on a generator by generator basis? 

Thank you,

Alex

Hi Alex,

For each VRE generator a time-series is usually attached with the
maximum available feed-in from the generators (`p_max_pu`). After you
solve the optimisation/dispatch problem, you can retrieve each
generator's dispatch during each timestep:

n.generators_t["p_max_pu"] # avail. feed-in per gen./timestep [per unit]

if you weigh it with n.generators["p_nom_opt"], the capacity for each
generator, then you get the curtailment per generator by calculating the
difference to:

n.generators_t["p"] # dispatch per gen./timestep


Best,
Johannes

Thanks Johannes, this was very helpful!

With the freshly released PyPSA v0.21 you can also give

network.statistics.curtailment()

which is a convenience function to do the same thing. :)

Best,
Johannes
