| Abstract: | The application of a general Compressed Air Energy Storage (CAES) power system design optimization methodology to the class of CAES plants having aquifer air storage reservoirs is discussed. The resulting procedure incorporates performance and economic models for the aquifer reservoir, wells, piping, and air compression system. Its use allows identification of designs which minimize the subsystem power generation cost (mills/kWh), while satisfying constraints related to the geology, equipment, and utility load curve. The design specification resulting from the optimization procedure includes: land area to be purchased, well depth, number of wells, well spacing, wellbore diameter, main pipeline diameter, required compressor system power and discharge pressure, and required compression time durations for each day of the week. A capital and operating cost summary for the optimum design is a final output of the procedure. The paper reviews the models and constraints incorporated in the optimization procedure. Although the basic framework is well-developed, some refinements or additions to the modeling may be necessary to improve the results; these possibilities are discussed. Results of case studies are included in order to illustrate the power and potential economic impact of the techniques described, to demonstrate some of the economic tradeoffs which occur in the optimal design of aquifer reservoir-based CAES systems, and to show the influence of certain cost parameters. |
