During normal operation, which component serves as the primary source of DC power for the DC electrical system?

DC power in normal operation comes from converting the power produced by the engine-driven generators. Those generators supply AC, and the DC converters rectify and regulate that AC into stable DC voltage for the DC buses. This arrangement keeps the DC system powered consistently as engine speed varies. The battery is used mainly for starts and emergencies, and the APU generator can supplement power when needed, but the regular DC supply is provided by the DC converters converting the generators’ AC output to DC.
