摘要：

In this paper, a synchronized control strategy of double fed induction generator that can provide reserve capability and primary frequency support for microgrid is firstly developed. The microgrid based small signal stability performance is investigated under multiple operating conditions. The effect of three categories of key controller parameters on dominant eigenvalues is studied by sensitivity analysis, including: 1) active power drooping coefficient; 2) reactive power drooping coefficient; 3) parameters of outer loop excitation current control. Finally, some constructive suggestions on how to tune controller parameters to improve microgrid's small signal stability performance are discussed.
