Comparing accuracy and runtime of simulation to the measurements in a real grid for the control of a grid-connected PV inverter

Abstract

The proposition for this study is to assess how much simulation results can differ from real measurements on the implementation of a control strategy for a grid-connected PV inverter. The system is simulated in Matlab/Simulink and experimentally evaluated on a real low-voltage distribution grid. The PV inverter is implemented using a power-hardware-in-the-loop platform running the control algorithm. The influence of linear and nonlinear loads and the interaction with another distributed energy resource operating on the same grid is quantified both in simulation and in the measurements. Finally, the control strategy is applied and the results for simulation and experimental setup are shown.
