Abstract
The increasing complexity of the dynamic behavior of low-voltage (LV) power grid makes it necessary for synchronous phasor measurement in LV grids. After a large disturbance, the dynamic behavior detected at the LV level is the coupling between dynamic behaviors of high-voltage (HV) major grid and LV local grid, which needs to be decoupled for different applications. This paper analyzes the response characteristics of LV power grid to a variety of common disturbances and proposes a mathematical model for the synchronized measurement data of high and low voltage grids. The coupling phenomenon of dynamic behaviors is explained for different load models. Finally, the theoretical analysis is verified by simulation.
