The proposed method is concerned with optimal scheduling of pump-storage hybrid system, aiming to maximize the hybrid system profit under frequency based pricing for a day ahead electricity market. The pump-storage hydro plant is utilized to minimize unscheduled interchange flow and maximize the system benefit by participating in frequency control based on energy price. Because of uncertainties in power generation of renewable sources, generation scheduling is modeled by a stochastic optimization problem. In order to verify the efficiency of the method, the algorithm is applied for various scenarios with different wind and photovoltaic power cases in a day ahead electricity market. The numerical results demonstrate the effectiveness of the proposed approach. %> http://ieijqp.ir/article-1-377-en.pdf %P 42-53 %& 42 %! %9 Research %L A-10-653-1 %+ Sahand University of Technology %G eng %@ 2322-2344 %[ 2017
