This work presents a mathematical model and control process of a three-phase VSC static synchronous compensator (STATCOM) in a hybrid grid made up of a 100 KW PV plant and a traditional power source. This approach is used to address the issues caused by the presence of both reactive and resistive loads at the common coupling point (PCC). The suggested control approach controls the STATCOM in a way that forces the source quadrature current component to zero, allowing only the active current component to be pulled from the source while the STATCOM satisfies the harmonic and reactive current requirements of the non-linear load. This approach will reduce the reactive power driven from the grid and eventually increase the transmission capacity and enhance the grid stability.
