AC lines and DC links capacity in myopic optimisation

[lisazeyen]

Currently, if one e.g. optimises the investment year 2030, all the optimised capacities from the previous year (in this case 2025) are neglected (this is happening here in add_browndfield.py). Probably duplicating each component of the transmission network for every investment period (as it is done e.g. for the onshore wind generators, with e.g. "DE0 0 onwind-2020", "DE0 0 onwind-2025",...) would slow down the optimisation but one could set the minimum capacity of each AC line and DC link on the optimised capacity of the previous year.

Here is a list of all the Link, Store and Generator carriers for which the previous optimised capacity is not considered. For all the other components (except for AC lines and DC links) it should be fine not to consider the previous optimised values (charger/discharger, gas store have no capital costs)

Link ['DC' 'co2 vent' 'BEV charger' 'V2G'
 'residential rural water tanks charger'
 'residential rural water tanks discharger'
 'services rural water tanks charger'
 'services rural water tanks discharger'
 'residential urban decentral water tanks charger'
 'residential urban decentral water tanks discharger'
 'services urban decentral water tanks charger'
 'services urban decentral water tanks discharger'
 'urban central water tanks charger'
 'urban central water tanks discharger' 'biogas to gas'
 'solid biomass for industry' 'gas for industry' 'process emissions']
Generator ['ror' 'lignite' 'coal' 'oil' 'uranium' 'gas']
Store ['lignite' 'coal' 'oil' 'uranium' 'co2' 'co2 stored' 'gas' 
 'battery storage' 'biogas' 'solid biomass']
