The application relates to the technical field of typical network configuration control, and discloses a stability domain adjustment method of a typical network configuration control strategy based on sequence impedance analysis, which aims to solve the shortcomings of a non-uniform stability domain framework, unclear MC control impedance characteristics, unclear parameter influence law and insufficient solution precision; the method establishes a control model of the typical network configuration control strategy, constructs a full-order small signal model based on small signal linearization disturbance processing, deduces a sequence impedance model in combination with the conversion relationship between positive and negative sequences and dq axis components, establishes a parameter-stability mapping relationship based on sequence impedance amplitude and phase characteristics in combination with gain margin and phase margin criteria, demarcates a stability domain range through two-dimensional parameter scanning and boundary fitting, and finally simulates and corrects the stability domain, so that the VSG control and the MC control stability domain can be accurately demarcated and compared horizontally, and the network configuration control parameter optimization and the power grid adaptability are improved.
