Abstract
This paper proposes a power smoothing scheme of a doubly-fed induction generator. The proposed scheme aims to mitigate system frequency deviation caused by the variable wind. To achieve this, a dynamic droop loop is used and its gain changes with rate of change of frequency so that it can release a large amount of kinetic energy at the initial stage of a frequency event. The performance of the proposed scheme was investigated in a model system with high wind penetration using EMTP-RV simulator. The test results indicate that the scheme can smooth the output power by absorbing or releasing the output power under a varying wind condition.
