ILS (Intelligent Load Shedding) 

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 a few milliseconds after a disturbance occurs in the system for transient events or after user-defined time delay for steady-state overload conditions.


Features and Benefits

  • Eliminate unnecessary load shedding
  • Reduction of downtime for critical loads
  • Reduction of spinning reserve requirements
  • Reliable load preservation system
  • Fast response to disturbances
  • Operator alerts for marginal operating conditions

Return on Investment 

Short-Term Savings

ETAP saves energy costs due to the overall system optimization and power loss reductions. Depending on the size of the facility, the expected average savings can be thousands of dollars per MVA of load per year. Savings can be considerably higher for systems that have abnormal losses, circulation power, or energy cost penalties. The informed decision-making is achieved through:

  • Prevention of human errors by predicting the system behavior based on the operator actions or disturbances
  • Increased system knowledge by utilizing up-to-date status of the system operating conditions
  • Short-term savings are also achieved by operators and engineers gaining experience with the power system operation and reaction.


Long-Term Savings

ETAP can provide a major reduction in the equipment capitalization cost by increasing equipment lifetime. Ongoing savings are achieved by continuously operating at a near-to-optimal condition and preventing possible system overload situations. Intelligent Load Shedding (ILS) will save you money by dynamically minimizing required load shedding, hence reducing system downtime. ETAP ILS load preservation system translates to savings of millions of dollars in lost revenues, equipment repairs, and penalties.
