Statcom is based on voltage source inverter that can be connected to the grid. It can be controlled in such a way that it can supply a particular desired value of reactive power or it can supply an amount of reactive power that is needed to keep the bus voltage at the Point of Common Connection (PCC) constant. Statcom is a power electronic device connected in shunt across the load to solve power quality problems, reduce fluctuations in bus voltage, reduce unbalance of three phase voltages and reduce flicker. Modeling of Statcom specifically to simulate for solving power quality problems presents various problems due to various types of control strategies.
