Design of Wide-Area Multi-Mode Controller Using Genetic Algorithm for Power System Stability

In wide-area power systems managing frequency and stability is crucial particularly given the complexities of interconnected networks and vast distances. The introduction of advanced control strategies is essential to enhance resilience, reliability, and stability across the network. This paper present an approach that integrates a wide area multi mode controller which is optimized using a genetic algorithm. The wide area Multi-mode controller(MMC) is implemented in the IEEE 9-bus system as a standard studying system. This study meticulously evaluates the MMC's performance and resilience in damping frequency oscillations under several challenging and critical scenarios including short circuits, communication latency, and failures in protection devices during these events and compared to others supplementary controllers. The results demonstrate that the MMC has best performance effectively in damping the oscillation mode within the system under critical conditions among the other controllers even when facing latency in communication and protection control signals.
