Not too sure about this "emergency power" term either
I'm not sure about the term, either, but the MD80's JT8D-200 engines, being mechanically controlled (non-FADEC), can deliver more than maximum rated thrust, if needed. This is called "MAX THROTTLE", and should be limited to stall and wind shear recovery at low altitudes; a normal go-around should not require more than maximum rated thrust.

If flight path control becomes marginal at low altitude, initiate the windshear recovery maneuver without delay. If ground contact appears imminent, either pilot calls “MAX THROTTLE.” Accomplish the first three steps simultaneously:

2. Aggressively apply maximum thrust [...]. To ensure maximum thrust is obtained with minimum delay, an overshoot to the mechanical stops is recommended until positive indications of recovery are confirmed
Similarly for stall recovery.
