Determination of optimal capacity for today energy storages has been specially noticed. The delay in increasing storage production capacity is one of the applications for energy storage supplies in which utilization from energy storage supplies along with improvement in the power status at peak hours of consumption may postpone the demand for installation of a new power plant module. In this essay, the optimal capacity of energy storage is determined in order to reduce exploitation costs by second-order non linear programming. This method expresses this problem with a target quadratic function based on the produced power of units and capacity of energy storage supply. The requirements have been modeled as linear equality and inequality equations. The related constraints for produced power and incremental and decremental power ratio in generators have been considered as well.
