چکیده    This paper focuses on improving the active and reactive power control of wind energy conversion system (wecs) by employing the battery energy storage system (bess) and controlling the frequency and voltage regulation instantaneously. the proposed power control scheme is composed of two control loops so that they are implemented and designed for active power control and controlling the reactive power, respectively, which both are equipped with pi type controllers. in addition, two control loops were utilized to control the frequency and voltage on the rotor side converter under balance and unbalance grid conditions. in this paper, the presented control strategy optimally tuned all the parameters of controllers at the same time by utilizing a mixed integer nonlinear optimization programming and solved by the ica algorithm. moreover, in order to demonstrate the effectiveness of the proposed strategy, non-linear time domain simulations were carried out in matlab software. the obtained simulation results verified that the proposed control scheme efficiently utilize bess to control the active and reactive power control and confirm the effectiveness of the proposed strategy under the balanced and unbalanced grid conditions.
