Abstract
In this paper, an estimation approach using Moving Horizon Estimator (MHE) is proposed to estimate online the grid impedance between DC/AC converters and the main grid. The proposed approach estimates the states, i.e., DC/AC converter output current, grid voltage, and grid impedance parameters using only voltage and current measurements at the connection point. The MHE is computed online from the Amazon Web Services, which receives the measurements via UDP protocol. Experimental results show that the proposed approach using MHE closely estimates the grid impedance parameters.
