Study of modeling method of distributed generators considering partial dropout for trunk transmission system

Simultaneous dropout of a large amount of distributed generators caused by a fault in a power line with voltage drop and/or phase change may worsen power stability of a trunk power system. A reduced model of distributed generators in secondary systems considering partial dropout is proposed for the...

Description
Summary:Simultaneous dropout of a large amount of distributed generators caused by a fault in a power line with voltage drop and/or phase change may worsen power stability of a trunk power system. A reduced model of distributed generators in secondary systems considering partial dropout is proposed for the stability analyses. To verify the reduced model, a detailed model and the proposed reduced model are compared under same conditions for a variety of load and fault conditions. For an example of practical applications, a relative comparison of power stability in IEE of Japan EAST 10 machine system model under fault ride through (FRT) requirements is demonstrated.
