Abstract
The performance of the power system can be affected by the variation in grid impedance. Hence, continuous monitoring of the grid impedance is very essential. This paper presents a method for the measurement of grid impedance variation in low-voltage network. The estimation method is computationally very simple, and it is dependent on the variance in voltage of the grid at two successive time sampling instants. A quadratic equation is formed using grid voltage. The proposed method is modeled in MATLAB Simulink to measure the grid impedance. Simulation results obtained in MATLAB Simulink are showing or demonstrating the efficacy of the measurement technique for discerning the impedance in low-voltage network.
