A system includes a primary, combustion turbine based system that includes one or more power shaft assemblies including a generator or motor/generator, a compressor and an expansion turbine associated with the one or more power shaft assemblies, and a combustor to feed the expansion turbine. The primary system includes a first flow network allowing outlet air from the compressor to pass downstream to the combustor for combustion and the expansion turbine for expansion. The primary system is modified by integration of an adiabatic compressed air energy storage sub-system that includes a compressed air store and a thermal energy storage system for removing and returning thermal energy to the compressed air upon charging and discharging the store. The sub-system includes a second flow network allowing outlet air from the compressor to pass, upon charging, to the compressed air store, and to pass, upon discharging, back to the combustor and/or expansion turbine. |

1. A hybrid combustion turbine power generation system (CTPGS) comprising:
a primary, combustion turbine based system, the primary system comprising one or more power shaft assemblies comprising at least a first generator or motor/generator, at least a first compressor and at least a first expansion turbine operatively associated with the one or more power shaft assemblies, and at least one combustor configured to feed the at least first expansion turbine, wherein the primary system comprises a first flow network allowing outlet air from the at least first compressor to pass successively downstream to the at least one combustor for combustion and the at least first expansion turbine for expansion, respectively, wherein the primary system is modified by integration of:
an adiabatic compressed air energy storage (ACAES) sub-system,the sub-system comprising at least one compressed air store and at least a first thermal energy storage (TES) system for removing and returning thermal energy to the compressed air upon charging and discharging the store, respectively, wherein the sub-system comprises a second flow network allowing outlet air from the first compressor to pass, upon charging, via the TES system to the at least one compressed air store, and to pass, upon discharging, back to the at least one combustor and/or first expansion turbine, via the TES system, wherein the hybrid CTPGS further comprises flow valve arrangements and mechanical coupling arrangements so configured as to provide the necessary flow and mechanistic connections to allow the hybrid CTPGS to be operable in at least the following modes of operation:—
(i) a power generating first mode in which the hybrid CTPGS produces power and the sub-system is not discharging; and,(ii) a power generating second mode in which the hybrid CTPGS produces power and the sub-system is discharging. |
