This paper presents a novel concept of utilizing adaptive corrective capability of the network for enhancing oscillatory stability limit.Researchers have analyzed this stability and suggested optimization of controller parameters for mitigating the problem. When such measures are found to be inadequate during operations and instability with expected load growth is imminent, the proposed approach shows how it is possible to tackle the problem by adaptive real and reactive controls rescheduling. This is achieved through reactive and real power optimization problems for optimizing the margin of oscillatory instability, which is periodically assessed in real time. Results for a sample test system demonstrate the feasibility of the proposed approach.
