This paper presents a novel concept of utilizing the photo voltaic solar farm inverter as STATCOM(Static Compensator), named PV-STATCOM, in order to improve the voltage profile of the power system. The entire STATCOM is able to transmit either active or reactive power into the grid. This system is connected to a 14 BUS IEEE standard grid as a case study to simulate the performance of the system. By decoupling active and reactive power, the inner loop control algorithm is used to trace the active power and the reactive power current separately. Meanwhile, outer loop regulates DC link voltage and grid-connected voltage. The simulation results shows that the photo voltaic system with STATCOM can improve the active power stably, keep grid connected voltage stable, and improve power quality of output voltage and current. Moreover the mathematical modeling of the whole system is verified. The simulation process is validated in MATLAB/SIMLULINK environment.
