Abstract

Recently, the electromechanical oscillations are becoming the primary concerns in power grids due to the integration of renewable energy generations (REGs). The inherent characteristics of REGs, e.g. low or no inertia, stochastic generation, could lead to the lower damping margin in power systems. A supplemental control such as power system stabiliser or power oscillation damping (POD) controller is widely applied to augment the damping margin in power systems. However, the PSS or POD using local signal is not adequate to damp the oscillation contributed from different sources. Hence, a wide-area damping controller can be employed in this context. Nonetheless, the wide-area controller suffers from communication failure. Therefore, the wide-area controller with resilient to communication failures is inevitable. This study proposed a wide-area POD design method considering resiliency. A modified differential evolution algorithm is employed to synthesise the wide-area damping control. The two-area and Java-Indonesian (three-area) power systems are used to evaluate the performance of the proposed controller for oscillation damping. From the results, it is evident that the critical mode(s) of the system successfully damped by employing the proposed controller. It is also found that the proposed controller is robust against communication failures.
