Reactive Power Compensation in Grid Connected Photovoltaic System Using Static Synchronous Compensator

Generally, when reactive power is considered, it is primarily focused upon the disadvantages and losses that it brings. Those are mainly active power losses, voltage losses, reduced power quality, deterioration of cos φ, etc. However, reactive power is an integral part in electrical grid and has its contributions. Reactive power is an essential factor in operation of electric motors as rotating magnetic fields are dependent on reactive power. Utilization of a photovoltaic (PV) system with static synchronous compensator (STATCOM) is a modern and efficient method of regulating active and reactive powers. In this paper is presented compensation of reactive power by utilizing a PV system with STATCOM connected to the grid. A simulation model in MATLAB/Simulink environment is also presented.
