Abstract:
1. A system, comprising: a gas turbine engine, wherein the gas turbine engine comprises a low pressure compressor, a high pressure compressor, an intercooler between the low pressure compressor and the high pressure compressor, a high pressure turbine, an intermediate pressure turbine, a low pressure turbine, and at least one combustor between the high pressure compressor and the high pressure turbine; an electrical generator coupled to the gas turbine engine, wherein the electrical generator is configured to output a power to a power grid; and a flywheel coupled to the gas turbine engine, wherein the flywheel is configured to store a rotational energy from the gas turbine engine, and the rotational energy stored by the flywheel is configured to resist changes in a rotational speed of the electrical generator to stabilize a frequency of the power during a grid destabilizing event on the power grid.
