Baseload electricity demand should match sum of demand curves

[marliekeverweij]

There is now some space between the baseload curves and the sum of all demand curves. We are probably missing a demand series in this chart, we have to find out which one!

[mabijkerk]

It seems to be caused by a missing series for electric vans. However, there are more issues with this chart:

• We distinguish only 'electric vehicles' merit_ev_demand and 'other' merit_transport_other_demand transport demand
• Electric vehicles only consists of cars, which is somewhat strange because trucks and vans are also electric vehicles
• The reasoning seems to be that electric cars charge at the LV network, as you can see in transport_car_using_electricity
• Both trucks and vans are connected to the MV network, which you can see in transport_car_using_electricity and transport_truck_using_electricity, and are therefore assigned to the 'other' category, along with all other electric transport demand (with the exception of electric cars)
• Vans are however missing from the underlying query of merit_transport_other_demand, which is mv_transport_load_curve, which is why it doesn't show in the chart

These network queries are very easily overlooked and not updated automatically, since each node is hardcoded into the query:

- query =
    SUM_CURVES(V(
      transport_bicycle_using_electricity,
      transport_bus_using_electricity,
      transport_freight_train_using_electricity,
      transport_motorcycle_using_electricity,
      transport_passenger_train_using_electricity,
      transport_tram_using_electricity,
      transport_truck_using_electricity,
      electricity_input_curve
    ))
- unit = curve

A more dynamic query that as far as I can tell obtains the same result is:

INTERSECTION(G(mv_net_demand),SECTOR(transport))

For transport_ship_using_electricity it is even stranger, because it does not seem to be included in the total either. This is probably because it has no network group assigned to it.

- groups = [application_group, freight_transport]

For now I would propose the following:

• [ ] Discuss with @marliekeverweij @mabijkerk and @Charlottevm whether we can update these queries in a more dynamic way or add some kind of test
• [ ] Discuss whether bicycles, motorcycles, vans and trucks should charge at LV or MV network
• [x] Add vans (and possibly) trucks correctly to the dynamic demand curve
• [ ] Update 'electric vehicles' series label if necessary
• [x] Discuss to which network ships should be added and add this group to the node file
• [x] Add ships to the chart
• [ ] Check if other recently added electricity demand curves may be missing from this chart
