Nowadays, price-based demand response (PDR) programs with compressed air energy storage (CAES) systems have been rapidly developed in China for wind power generation propagation. Based on this development trend, an optimal scheduling model considering thermal power units (TUs), wind power plants, PDR mechanisms and CAES plants is studied in this paper. Considering the factors of uncertainties in PDR, wind power output and electricity demand, a fuzzy power system optimal scheduling model for minimizing the sum of TUs operation cost, CAES plants cost and wind curtailment penalty is proposed. According to the fuzzy scheduling theory, the fuzzy chance constrains are converted into their clear equivalent forms. The simulation study is implemented with using the data from the Huntorf CAES plant, which can verify the feasibility and effectiveness of the optimal scheduling model. It is found that the use of CAES and PDR results in 11.1% reduction in thermal power units operation cost and 71.6% reduction in the penalty of wind curtailment.
