Undefined buses for (H2 pipeline) links

Describe the Bug

We have observed a behaviour in the sector-coupled version of PyPSA-Earth, in which the buses for (H2 pipeline) links are not properly connected. This results in a warning (see below), and leads to wrong H2 balances since pipelines "create" hydrogen. This has been observed by @doneachh for Ethiopia, and also by @hazemakhalek (see #1463 (comment))

Error Message

Warning:

Resulting H2 balance, in which H2 pipelines "create" H2 (reported by @doneachh):

@energyLS many thanks for opening an issue on that!

Just flagging that same issues have been found in a modeling project for both CO2 pipelines and biomass transport. @SermishaNarayana @davide-f and @hazemakhalek have found that having links which are not connected to a bus leads to the weird behaviour similar to what is observed for H2 in this issue

[doneachh]

@energyLS @ekatef My guess is that this is related to gadm clustering when there is no load on a bus. As soon as I switch the alternative_clustering parameter, I get realistic values. We already had a workaround PR for the no load on bus case: #1432
But I think we need to look at this again.

[Eric-Nitschke]

@energyLS the pipelines creating hydrogen sounds a bit like what I observed in #1213. Maybe its worth ckecking, whether its the same issue and if my original fix for it (#1192) still works.

Hi all,

I managed to recreate this with a minimal PyPSA example. This seems to happen when you have a link that is not connected to bus from one end, seems to be working as a source. This doesn't happen anymore, I tested it with newest PyPSA version.

import pypsa
import random
import numpy as np


nt = pypsa.Network()
hours = 24  
nt.set_snapshots(range(24))

no_of_buses = 4  # Define the number of buses
link_p_min_pu = -1  # Minimum power flow as a fraction of p_nom

for i in range(no_of_buses):
    nt.add("Bus", f"Bus {i+1}")

# Connect buses with links 
for i in range(4):
    nt.add("Link",
           f"Link {i+1}",
           bus0=f"Bus {i+1}",
           bus1=f"Bus {(i+1)%5 + 1}",
           p_nom=100,
           p_min_pu=link_p_min_pu,)  # bidirectionality


# Add generators with random parameters to each bus
for i in range(4):
    nt.add("Generator",
           f"Gen {i+1}",
           bus=f"Bus {i+1}",
           p_nom=random.uniform(50, 150),  
           marginal_cost=random.uniform(20, 80), 
           efficiency=random.uniform(0.3, 0.6))

# Add different load profiles to each bus
for i in range(3):
    # Create a daily load profile with randomness
    base_load = random.uniform(30, 70)
    profile = base_load + 10 * np.sin(np.linspace(0, 2 * np.pi, hours)) + np.random.normal(0, 3, hours)
    nt.add("Load",
           f"Load {i+1}",
           bus=f"Bus {i+1}",
           p_set=profile)
    
nt.consistency_check()
nt.optimize()
#nt.lopf()
print(nt.statistics.energy_balance().round())

This gives the below energy balance when using an older version of PyPSA. In the case of the project I was checking it is 0.24.0:

If you however change the no_of_buses to be 5, so that no link is "dangling", the results is as below:

With newer versions PyPSA throws an error, see below:

[doneachh]

Debugged a little bit more in detail:

When jumping into the prepare_sector_network scripts, I've set a breakpoint and observed:
print(n.loads[~n.loads.bus.isin(n.buses.index)])
Empty DataFrame
Columns: [bus, carrier, p_set, q_set, sign, type]
Index: []

print(n.links[["bus0", "bus1"]].apply(lambda x: x.isin(n.buses.index)).all(axis=1).value_counts())
True 38
Name: count, dtype: int64

At the end of the script:
print(n.loads[~n.loads.bus.isin(n.buses.index)])
bus carrier p_set q_set sign type
Load
ET.2_1_AC H2 for industry ET.2_1_AC H2 H2 for industry NaN 0.0 -1.0
ET.2_1_AC land transport fuel cell ET.2_1_AC H2 land transport fuel cell 0.0 0.0 -1.0

print(n.links[["bus0", "bus1"]].apply(lambda x: x.isin(n.buses.index)).all(axis=1).value_counts())
True 477
False 11
Name: count, dtype: int64

--> We're creating most of the invalid entries in all the functions in prepare_sector_network (add_industry(), add_land_transport()) - i guess we have to check here whether buses are existent in clusters

[doneachh]

I (or chatGPT) implemented a debugging function and investigated more in depth:

def debug_invalid_bus_references(n):    
    single_bus_comps = ["loads", "generators", "stores", "storage_units", "shunt_impedances"]
    dual_bus_comps = ["lines", "transformers"]
    bus_set = set(n.buses.index)

    print("🔍 Checking for invalid bus references...\n")

    # Single bus components
    for comp in single_bus_comps:
        df = getattr(n, comp, pd.DataFrame())
        if "bus" in df.columns:
            invalid = df[~df["bus"].isin(bus_set)]
            if not invalid.empty:
                print(f"⚠️  {comp}: {len(invalid)} entries with invalid 'bus' values.")
                print(f"    → {invalid.index.tolist()}")

    # Dual bus components (lines, transformers)
    for comp in dual_bus_comps:
        df = getattr(n, comp, pd.DataFrame())
        if {"bus0", "bus1"}.issubset(df.columns):
            mask = df["bus0"].isin(bus_set) & df["bus1"].isin(bus_set)
            invalid = df[~mask]
            if not invalid.empty:
                print(f"⚠️  {comp}: {len(invalid)} entries with invalid 'bus0' or 'bus1'.")
                print(f"    → {invalid.index.tolist()}")

    # Multi-bus components (links)
    df = getattr(n, "links", pd.DataFrame())
    bus_cols = [c for c in df.columns if c.startswith("bus")]
    if not df.empty and bus_cols:
        valid_mask = df[bus_cols].apply(lambda x: x.isin(bus_set)).all(axis=1)
        invalid = df[~valid_mask]
        if not invalid.empty:
            print(f"⚠️  links: {len(invalid)} entries with invalid bus columns {bus_cols}.")
            print(f"    → {invalid.index.tolist()}")

    print("\n✅ Bus reference check complete.")

Here my results:

Investigated further:
The main problem leading to all these components with undefined buses ist, that there is one bus missing in pop_layout.index, which is existing in nodes (ET.2_1).

As we're using spatial to add all these components, we get all these components with undefined buses.

So I investigated further:
--> build_population_layout and build_clustered_population_layout already have the one bus missing

--> cluster_network: Until
clustering = get_clustering_from_busmap( n, busmap, aggregate_generators_weighted=True, aggregate_generators_carriers=aggregate_carriers, aggregate_one_ports=["Load", "StorageUnit"], line_length_factor=line_length_factor, line_strategies=line_strategies, bus_strategies=bus_strategies, generator_strategies=generator_strategies, one_port_strategies=one_port_strategies, scale_link_capital_costs=False, )
the bus 'ET.2_1' is existing, afterwards we have just 9 buses.

Unfortunately this function is part of pypsa and i can not debug any further here, but i guess in this function is the source of the error.

[doneachh]

Tried to investigate the clustering further afterwards:

ET.2_1_AC gets clustered into ET.8_1_AC, which does not make any sense as we then just have 9 buses for 10 clusters

for old_bus, new_bus in busmap.items():
    if new_bus == "ET.2_1_AC":
        print(old_bus)

60

print(clustering.busmap[old_bus])
ET.8_1_AC

[doneachh]

Interesting: all components of this bus are empty --> will investigate why there is no load, generators and storage units in this node.

print(n.loads[n.loads.bus == "Bus 60"])
print(n.generators[n.generators.bus == "Bus 60"])
print(n.storage_units[n.storage_units.bus == "Bus 60"])

Strategies to fix it:

• find out, why there is no load, generators and storage units
• fix it either with creating dummy load, generator and storage units in front of "get_clustering_from_busmap()"
• fix it by using nodes instead of population_layout.index when defining spatial in prepare_sector_network

@hazemakhalek @davide-f @energyLS
Found the error:
If “remove_stubs” is enabled in the config, the loads, generators, and stores are removed from bus ET_2_1 in simplify_network and added to bus ET_8_1.

Disabling remove_stubs results in realistic marginal prices.

Nevertheless, we should think about how we can ensure that no bus is left without load, etc. when remove stubs is enabled to ensure realistic behaviour in all cases.
How should we proceed with this?
