Merge two networks as DSO/TSO network? #2352
Comments
@samabu2011 you can merge two networks. It should work, but you have to identify the merging points / busses. What exactly do you mean with one functions as dso and one as tso? |
Thanks for the answer! I would like to construct an example where I can use two of the IEEE cases from here: https://pandapower.readthedocs.io/en/v2.1.0/networks/power_system_test_cases.html#pandapower.networks.case24_ieee_rts and build a new network with them. Ideally one would represent a TSO and one would respresent DSO, such that I can do some further simulations. Currently for example I am trying to connect case14() as a TSO with case4gs() playing the role as a DSO. How would you identify the merging points and busses? Here is the code example I am using, but I am unsure if it is correct: import pandapower as pp def fix_nan_values_in_boolean_columns(net): Load the IEEE 14-bus system as the TSO networktso_net = pn.case14() Load the IEEE 4-bus system as the DSO networkdso_net = pn.case4gs() #pplot.simple_plotly(tso_net) #pplot.simple_plotly(dso_net) Add a bus in the TSO network to connect the DSOtso_bus_new = pp.create_bus(tso_net, vn_kv=135, zone = 1.0, name="TSO Bus New") Connect the new bus in the TSO network to an existing bus in the TSO network with a linepp.create_line(tso_net, from_bus=1, to_bus=tso_bus_new, length_km=10, std_type="149-AL1/24-ST1A 110.0") Add a transformer to connect the TSO bus and the DSO buspp.create_transformer(tso_net, hv_bus=tso_bus_new, lv_bus=dso_net.bus.index[0], std_type="25 MVA 110/20 kV") #pplot.simple_plotly(tso_net) Ensure there are no NaN values in boolean columns in all elements of the networksfix_nan_values_in_boolean_columns(tso_net) Merge the networksmerged_net = pp.merge_nets(tso_net, dso_net, std_prio_on_net1=True, net2_reindex_log_level='INFO', return_net2_reindex_lookup=False) Run power flow calculation`import pandapower as pp def fix_nan_values_in_boolean_columns(net): Load the IEEE 14-bus system as the TSO networktso_net = pn.case14() Load the IEEE 4-bus system as the DSO networkdso_net = pn.case4gs() #pplot.simple_plotly(tso_net) #pplot.simple_plotly(dso_net) Add a bus in the TSO network to connect the DSOtso_bus_new = pp.create_bus(tso_net, vn_kv=135, zone = 1.0, name="TSO Bus New") Connect the new bus in the TSO network to an existing bus in the TSO network with a linepp.create_line(tso_net, from_bus=1, to_bus=tso_bus_new, length_km=10, std_type="149-AL1/24-ST1A 110.0") Add a transformer to connect the TSO bus and the DSO buspp.create_transformer(tso_net, hv_bus=tso_bus_new, lv_bus=dso_net.bus.index[0], std_type="25 MVA 110/20 kV") #pplot.simple_plotly(tso_net) Ensure there are no NaN values in boolean columns in all elements of the networksfix_nan_values_in_boolean_columns(tso_net) Merge the networksmerged_net = pp.merge_nets(tso_net, dso_net, std_prio_on_net1=True, net2_reindex_log_level='INFO', return_net2_reindex_lookup=False) Run power flow calculationpp.runpp(merged_net)` |
Hi
I was wondering if and how you can use the merge function to merge two networks such that one functions as a dso and one as TSO?
