A microturbine power generating system includes an electrical generator and a turbine having a fixed inlet nozzle geometry. Maximum thermodynamic efficiency of the microturbine power generating system is achieved by maintaining the turbine inlet at or near maximum temperature. When power demanded of the system is constant, power is supplied by the electrical generator. When an increase in power is demanded, at least a portion of the entire demand is supplied by a battery or other energy storage device until the electrical generator can satisfy the increased power demand. Conversely, when a decrease in power is demanded, the load on the generator is temporarily increased (effectively putting a brake on the generator and turbine) and such load is absorbed by the battery or other energy storage device.

[ What is claimed is:] [1.] A method of controlling the turbine of a turbine powered generating system regardless of the load on said system, to maximize the efficiency of said turbine, said turbine having a fixed inlet nozzle geometry, said system further including an electrical generator, and a storage device, said method comprising:(a) maintaining said inlet nozzle at a substantially constant temperature;(b) using said electrical generator to satisfy the power demand on said system until said system is required to satisfy an additional power demand;(c) when said additional power is demanded, temporarily using said storage device to satisfy said additional power demand and at least a portion of said power demand;(d) increasing the speed of said turbine from the speed required to satisfy said power demand to a higher speed required to satisfy said power demand and said additional power demand; and(e) once said higher speed is achieved, using said electrical generator to satisfy both said power demand and said additional power demand.
