Description
Summary:Hybrid dynamic simulation is an important tool for power system simulation and validation. In this paper, a hybrid dynamic simulation method of power system is proposed based on impulse load injection, which directly injects the measured data containing constant power and impulse power into the simulation subsystem to achieve decoupling between subsystems. This method avoids the simulation error that may be caused by the dynamic equivalent of the external system. Based on the load model provided by the commercial software PSASP and the inherent impulse disturbance module, the proposed method is simple and easy to implement, and avoids the use of UPI/UD to write the interface program, thus having high practicality. A case study is conducted on an IEEE 10 machine 39-bus test system and a provincial power grid, which has verified the effectiveness of this method.
