Improving Primary Frequency Control of Wind Integrated Power System with RFB

The employing of Redox Flow Battery (RFB) for enhancing primary frequency capability of a power system with wind integration is presented in this paper. Differential evolution algorithm is manipulated for tuning the parameters of PID controller. The frequency and tie-line power variations of a multi-area, diverse source network is analyzed for better understanding. The system is examined to operate under three different wind penetration levels with and without inertial support from a wind turbine. The influence of RFB in enhancing the virtual inertial support with the wind turbine is also investigated.
