    Abstract: With the continuous access of the microgrid, the randomness and intermittence of its output have brought challenges to the voltage control of the distribution network. The concept of reactive power-voltage sensitivity is proposed, and a reactive power control space matrix of microgrid is considered considering the effect of microgrid reactive power output on node voltage of distribution network. According to the obtained micro-grid reactive power control space matrix, the hierarchical clustering analysis method is used to partition the distribution network. Finally, taking IEEE 33 Node System as an example, based on MATLAB Simulink simulates the reactive power control capability under microgrid interconnection. It focuses on the analysis of the voltage adjustment process of the nodes in the microgrid, under the condition of sudden load increase and sudden load decrease, and verifies the rationality of the reactive power control partition.
    Key words: microgrid; reactive control space matrix; hierarchical clustering; distribution network
