One example provides a method for generating and using electric power in a hybrid power system for an aircraft. The hybrid power system has an engine and a high-voltage DC (HVDC) bus interconnecting a generator-motor system, an AC distribution system, and a DC distribution system. The method comprises operating the engine through a plurality of different operation phases. The method further comprises selectively providing, based on thrust demands of the engine, electric power from the HVDC bus to the generator-motor system to assist the engine in providing thrust. The method further comprises selectively extracting, using the engine driving the generator-motor system with a high-pressure spool (HPS) shaft and/or a low-pressure spool (LPS) shaft of the engine, electric power from the engine. The method further comprises selectively delivering the electric power extracted from the engine to the AC distribution system and/or the DC distribution system.
