At least one controller manages a gas turbine engine driving a generator directly or indirectly coupled to the engine. The controller is programmed to automatically determine and adjust inputs to the gas turbine engine in order to cause the generator to produce a user-specified electrical output. Multiple sets of generator, engine, and controller may be used, in which case a master controller individually manages the other controllers to collectively provide the a user-specified electrical output.

1. A power generating system, comprising: multiple generators each coupled to a common grid via a corresponding switch, each generator driven by a different gas turbine engine; andat least one controller coupled to the gas turbine engines, each of said at least one controller programmed to employ a predetermined computer-driven strategy to calculate and individually adjust target mechanical outputs of the gas turbine engines such that the generators supply a user-specified electric output to the common grid;where each of said at least one controller is programmed such that the predetermined computer-driven strategy comprises applying the following proportional-integral-differential (PID) control loops:a first-level PID control loop programmed to receive user-specified electric output of the power generating system, to receive measured electric output of the power generating system, to receive operating limitations including electrical limits of the generators and switches, and to provide output including an individual targeted electric output for each of the generators;a second-level PID control loop associated with each generator, where each of the second-level PID control loops is programmed to receive input including the targeted electric output for the associated generator from the first-level PID control loop, to receive measured electric output of the associated generator, to receive operating limitations including electrical limits of the associated generator and its corresponding switch, and to provide output including targeted engine output for the gas turbine engine coupled to the associated generator;a third-level PID control loop associated with each generator and the second-level PID loop associated with the generator, where each of the third-level PID control loops is programmed to receive targeted engine output from the associated second-level PID loop, to receive sensed engine conditions including temperature, speed, and torque, and to provide output including air, fuel, ignition, or other combustion inputs for application to the gas turbine engine driving the associated generator. 2. A method of operating a power generating system, comprising operations of: providing multiple generators each coupled to a common grid via a corresponding switch, each generator driven by a gas turbine engine;providing at least one controller coupled to the gas turbine engines; andeach of said at least one controller employing a predetermined computer-driven strategy to calculate and individually adjust target mechanical outputs of the gas turbine engines such that the generators supply a user-specified electric output to the common grid;the predetermined computer-driven strategy comprises applying the following proportional-integral-differential (PID) control loops:a first-level PID control loop programmed to receive user-specified electric output of the power generating system, to receive measured electric output of the power generating system, to receive operating limitations including electrical limits of the generators and switches, and to provide output including an individual targeted electric output for each of the generators;a second-level PID control loop associated with each generator, where each of the second-level PID control loops is programmed to receive input including the targeted electric output for the associated generator from the first-level PID control loop, to receive measured electric output of the associated generator, to receive operating limitations including electrical limits of the associated generator and its corresponding switch, and to provide output including targeted engine output for the gas turbine engine coupled to the associated generator;a third-level PID control loop associated with each generator and the second-level PID loop associated with the generator, where each of the third-level PID control loops is programmed to receive targeted engine output from the associated second-level PID loop, to receive sensed engine conditions including temperature, speed, and torque, and to provide output including air, fuel, ignition, or other combustion inputs for application to the gas turbine engine driving the associated generator.
