2022 scenario peak PV production is too low #8

Closed MaykThewessen closed 2 years ago

MaykThewessen commented 2 years ago

too much DC/AC fixed in. the model, in reality this is less, so spikes are higher

since currently only 10GW max occurs with 14.8GWp in model

in reality it will be closer to 12 or so - so task: reduce flexibility dc/ac ratio of pv in ETM and export data set again

MaykThewessen commented 2 years ago

maybe this isn't a real problem, maybe it is realistic, thus low priority

MaykThewessen commented 2 years ago

sunday 24 april: 10.05GW actual production dutch PV estimated by function installed NL capacity: 14.8 GWp thus ratio: 67,9%

in my code: actual max production solar: 8.22 GW max in april! this is low, and the max stays the same the rest of the year ratio: 55.5% hypothesis: probably due to max AC/DC ratio's set in ETM model:

problem with this is: non true value of PV curtailment, + non true accuracy for possible V2G charge moments etc

MaykThewessen commented 2 years ago

Updated ETM, reduced all curtailment settingwith 5% points, to match current NL situation more closely:

note: in 2030 actual average fixed curtailment will be higher, since paradigm shifts occurs with newly installed PV installations due to electricity prices flooring during 11-14h on sunny days, and due to SDE++ regulations having 30 or 50% fixed curtailment and due to increased difficulty of having transport capacity available to new PV projects

MaykThewessen commented 2 years ago

this now results in having zero prices in 2022 as well! the little higher power in PV pushes residual load negative in 2022 as well already, this also activates V2G for a very small part

so it did make an impact that is useful, glad to have done it
