摘要：

Assessment of node importance is essential for the reliable operation of microgrids. The absence of key nodes for voltage support during voltage deviation may significantly escalate the severity of an incident. Distributed generators in microgrids are highly susceptible to going off-grid during disturbances and are more likely to experience node failure. This study proposes a voltage support capability assessment method for distributed generators, which integrates the electrical characteristics of microgrids with the structural features of graph theory, enabling an accurate assessment of the voltage regulation capabilities of distributed generators. The concurrence of time-domain simulation and calculation results demonstrates the effectiveness of the proposed method in identifying key nodes for voltage support.
