Question
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.
Solution
The correct statement is "The AC-DC distribution system is more complex than a pure AC distribution system." This is because an AC-DC system involves both alternating current (AC) and direct current (DC) components, which adds complexity in terms of design, control, and operation. The other statements are not necessarily true. The number of elements in an AC-DC system can vary and may not necessarily be fewer than in a pure AC system. Also, while some load flow methods for transmission systems may be applicable to AC-DC distribution systems, this is not always the case due to the different characteristics and requirements of these systems.
