PSS Design for a Single-Machine Power System Using Honey Bee Mating Optimization

A Honey Bee Mating Optimization (HBMO) technique is proposed for the optimal tuning of the Power System Stabilizer (PSS) in this paper. The design problem of robustly selecting PSS parameters is formulated as an optimization problem according to the time domain-based objective function which is solved by the HBMO technique that has a strong ability to find the most optimistic results. To achieve desired level of robust performance and improve power system low frequency oscillations damping, The design process takes a wide range of operating conditions. The effectiveness of the proposed HBMO based PSS is demonstrated on a Single-Machine Infinite-Bus (SMIB) power system through the nonlinear time domain simulation and some performance indices under different operating conditions in comparison with the genetic algorithm based tuned stabilizer and conventional PSS. Results evaluation show that the designed HBMO based PSS has an excellent capability in damping power system low frequency oscillations and enhance greatly the dynamic stability of the power systems.
