Grid feeders

Grid feeders are considered as fix power or current sources in the power flow calculation.

"grid_feeders":[{"bus": "Bus_2","bus_nodes": [1, 2, 3,4],
                 "kW": [0.5,0.5,0.5], "kvar": [0,0,0],
                 "kA": [0,0,0], "phi_deg":[30, 30, 30]}
               ]

where:

• "bus": name of the bus
• "bus_nodes": list of nodes where the grid former source is connected
• "kW": active power for each phase
• "kvar": reactive power for each phase
• "kA": RMS value of the current in each phase
• "phi_deg": angle between voltages and currents
