What is/are the challenges of AC-DC load flow analysis? Requires proper modeling of various types of power converters in the load flow equations. Requires modeling of storage and various DC loads. Modeling of various types of distributed generations (PV Systems, Geothermal, Wind Generators, Hydropower, etc.) is difficult. All of the above

Select the correct statement. The AC-DC distribution system is more complex than a pure AC distribution system. The AC-DC distribution system has fewer elements. Available load flow methods for transmission systems can also be applied to AC-DC distribution systems. All are correct.
