1. A system for pre-heating a gas turbine (GT) engine of a power generation system in a standby mode, the system comprising:
a first heated fluid manifold coupled to the GT engine;
a first conduit coupling a heated fluid supply external to the GT engine to the first heated fluid manifold;
a first plurality of valves configured to control an amount of heated fluid flow through the first conduit between the heated fluid supply and one or more fatigue-prone components of the GT engine; and
a controller in communication with the first plurality of valves, wherein the controller;
selects a position of at least one of the first plurality of valves based on a temperature of the one or more fatigue-prone components, and
adjusts an open extent of at least one of the first plurality of valves to the position to control the temperature of the one or more fatigue-prone components based on an operating condition of the GT engine.
