Abstract

The reactive nature of traditional frequency stability schemes can lead to delayed corrective actions and unnecessary loss of load. This work presents a complete framework for proactive system frequency stability via PMUs and the particle filter. By being able to estimate the future state of frequency, corrective actions can be taken before the system reaches a critical condition. This proactive approach makes it possible to optimize the response to a disturbance, which results in a decrease in the amount of compensation utilized. The framework was tested via Matlab simulations based on Kundur’s Two-Area System, and the IEEE 14-Bus system. The results were promising and outperformed other contemporary solutions by drastically reducing the amount of load dropped during compensation.
