Grey Wolf Optimizer Applied to the Wide-Area Damping Controller Design

Data from PMUs from remote locations proved to be useful for improving the observability of power systems and many applications have been proposed. The development of the Wide-Area Damping Controller (WADC) that uses data from PMUs is effective in damping control of inter-area oscillation modes of power systems. However, the design of WADC robust to communication failures is still a challenge. This article proposes an optimization model for the design of WADC robust to communication failures, the metaheuristic Grey Wolf Optimizer is used to solve the optimization problem and an initialization procedure for the variables of the optimization problem is proposed. Case studies are presented and discussed for the IEEE 68 bus system.
