Reinforcement Learning Based Wide-Area Decentralized Power System Stabilizers

In this paper, the design of a real-time control framework consisting of wide-area decentralized power system stabilizers (WD-PSSs) for enhancing transient stability and oscillatory stability of power systems is investigated. The design is based on reinforcement learning methods incorporating wide-area measurements. The main goal of WD-PSSs is to stabilize a power system after a disturbance leading to transient instability. In addition, WD-PSSs are able to improve the damping of oscillations in the system. The proposed control framework is implemented using the 10-generator 39-bus power system. Simulation results are illustrated to validate the proposed design.
