A fast load shedding remedial action scheme using real-time data for BC Hydro System

In this paper, a fast load shedding remedial action scheme is introduced for the BC Hydro system. The shedding scheme has been developed based on the dynamic and steady state responses for different system contingencies in order to mitigate transient instability and voltage collapse. The shedding amount is calculated and updated depending on the real-time data collected from Energy Management System (EMS). In the developed scheme, shedding candidates are selected based on the sensitivity analysis regarding the load impacts on voltage profile and transient performance of the system. The developed scheme has been verified for different system contingencies using PSS/E dynamic simulation.
