Optimal & Fast Solution
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.

Shed Less Load with ILS
The longer that it takes to shed load during a disturbance, the more load that must ultimately be shed. Because of the intelligence and speed of ILS, the actual amount of load that is shed is far less than that of using the conventional methods such as frequency relay and PLC-based schemes.
Unlimited Load Schedules
EMS is utilized for power system planning, design, and operation optimization. Demand-Side Management (DSM) produces a more reliable and economical operation, while maintaining the power systems operational integrity. EMS state-of-the-art load management application provides intelligent load flow solutions to minimize operating costs and maximize system performance. EMS allows you to maximize the value of your energy investment.
