Abstract :
Following the large development of grid, the emerging problem of reactive power and voltage mismatch is given an in-depth analysis in this paper, and the ideal control state and mismatch control state are distinguished. Then for the problem of reactive power and voltage mismatch, this paper presents a method of power Jacobian matrix and level of sensitivity to analyze the problem qualitatively in order to acquire the regulation strategy and direction. Finally, the Example of 14- bus system shows it is an effective method in the analysis.
