Abstract

This paper proposed a novel multi-input multi-output (MIMO) linear zero dynamic controller (LZDC) for a three-phase grid-connected photovoltaic (PV) system. The relative degree is investigated through the concept of Lie derivative to execute the LZDC for three phase grid connected PV system. To implement the control theory, system stability is checked by the LZDC scheme. The linear zero dynamic control law is obtained to control the injected power into the grid through the system's inverter. Finally, the simulation results are presented to show the performance of MIMO LZDC scheme with weather disturbances such as 10%, 20%, and 30% sunshade on the PV strings and also proved that the system operated at the unity power factor.
