RequiredSvVoltage

Possible fix

    # Fix missing injection voltages
    # Injections <- Terminal -> Topological Nodel <- Voltage
    injections = solved_data.type_tableview('EquivalentInjection').reset_index()
    injections = injections.merge(solved_data.type_tableview('Terminal').reset_index(), left_on="ID", right_on="Terminal.ConductingEquipment", suffixes=("_Injection", "_Terminal"))
    injections = injections.merge(solved_data.type_tableview('SvVoltage'), left_on="Terminal.TopologicalNode", right_on="SvVoltage.TopologicalNode")
    injections = injections.merge(solved_data.type_tableview('SvPowerFlow'), left_on="ID_Terminal", right_on="SvPowerFlow.Terminal")
    injections[['ID_Injection', 'EquivalentInjection.p', 'EquivalentInjection.q', 'ACDCTerminal.connected', 'SvVoltage.angle', 'SvVoltage.v', 'SvPowerFlow.p', 'SvPowerFlow.q']]

if #125 is solved then pypowsybl ver 1.6.0 can solve this issue (maybe need to check duplicate values). Update: still an issue over there: for one boundary node between two igms it gives two separate sets values (probably calculated from each igm side).

In newer version it iterates over the dangling lines to get the voltage values

private static void writeVoltagesForBoundaryNodes(Network network, String cimNamespace, XMLStreamWriter writer, CgmesExportContext context) throws XMLStreamException {
        for (DanglingLine dl : network.getDanglingLines(DanglingLineFilter.ALL)) {
            Bus b = dl.getTerminal().getBusView().getBus();
            String topologicalNode = dl.getProperty(Conversion.CGMES_PREFIX_ALIAS_PROPERTIES + CgmesNames.TOPOLOGICAL_NODE_BOUNDARY);
            if (topologicalNode != null) {
                if (dl.hasProperty("v") && dl.hasProperty("angle")) {
                    writeVoltage(topologicalNode, Double.parseDouble(dl.getProperty("v", "NaN")), Double.parseDouble(dl.getProperty("angle", "NaN")), cimNamespace, writer, context);
                } else if (b != null) {
                    writeVoltage(topologicalNode, dl.getBoundary().getV(), dl.getBoundary().getAngle(), cimNamespace, writer, context);
                } else {
                    writeVoltage(topologicalNode, 0.0, 0.0, cimNamespace, writer, context);
                }
            }
        }
    }

Quick Fix, drop one of the boundary SV results in post processing.

TODO - @mr0321 please reports this issue to Powsybl project

It seems that this is an intentional behaviour: If two dangling lines with the same Xnode are in the same geographical region in a CGMES file, they are not merged #2389
