Optimal power flow-based generation shedding for dynamic remedial action scheme

An optimal power flow (OPF)-based generation shedding for dynamic remedial action scheme (RAS) is proposed in this paper. A straightforward generation-shedding cost function is developed using pre-RAS and post-RAS OPF costs. The proposed method updates RAS control actions online based on the system operating conditions and cost functions. The proposed method is tested on a modified IEEE 39-Bus system. Test results demonstrate effectiveness of the proposed generation-shedding method.
