The future Indonesian power grid will have significant REGs, especially in Java Island. Wind and solar photovoltaic (PV) will be the dominating technologies in future Indonesian grid. Although REG can provide clean and sustainable energy, they also cause undesirable effects on system stability due to the uncertainty in their output and different dynamic characteristics. Battery energy storage system (BESS) has been considered as the promising candidate to manage the intermittency and low inertia associated with wind and PV in many future power systems. In addition to the normal functionality, the resilient wide-area power oscillation damping (POD) can be implemented in the BESS to damp the low-frequency oscillation in the system. This research proposes a method to design a resilient wide-area POD in BESS. A grey wolf optimiser (GWO) has been used to synthesise the resilient wide-area POD. The representative dynamic model of Java-Indonesian power system is used to evaluate the performance of the GWO-based resilient wide area POD. From the results, it is evident that the implementation of the proposed controller at BESS successfully damped the critical mode of the system. It is also observed that the proposed controller is robust against the failure of the input signal.
