The transient response of power electronic loads is unlike traditional linear loads. Therefore, a composite power electronic transient load model is developed. The load model dynamics are validated with actual utility voltage sag response data, laboratory controlled load response testing, and power electronic load dynamic simulations. The power electronic load model is applied in the University of Texas at Austin power system. The system transient response is unique and considerably different from what it would be with traditional linear loads. The power electronic load can be friendly or unfriendly to the system depending on the fault and system configuration.electronicengCopyright is held by the author.
