ETAP Intelligent Load Shedding (ILS) provides optimal, fast load shedding for electrical disturbances and loss of generation.

ILS calculates the minimum required MW to be shed for each subsystem according to the type and location of the disturbance, actual operating generation, spin reserve, loading, configuration, load distribution, and priority. ILS then selects the best combination of loads (CBs) that will satisfy this requirement. All of this is executed in less than 100 ms after a disturbance occurs in the system.

Load Preservation first calculates the minimum required power to be shed for each subsystem and accordingly selects the optimal combination of loads that will satisfy the requirements.

Load Restoration monitors system operating conditions after a load shedding event and restores loads while maintaining system stability and reliability.

Load Shedding Validation evaluates and confirms load shedding decisions in real-time mode. ETAP ILS integrates with the ETAP Transient Stability Analysis module to simulate and verify the load shedding requirements and recommendations before system commissioning.
