Load rejection

Load rejection in an electric power system is the condition in which there is a sudden load loss in the system which causes the generating equipment to be over-frequency.

A load rejection test is part of commissioning for power systems to confirm that the system can withstand a sudden loss of load and return to normal operating conditions using its governor.<ref>"ASME DC | Journal of Engineering for Gas Turbines and Power | Load Rejection Tests and Their Dynamic Simulations With a 150 kW Class Microsteam Turbine".
