This paper presents the mathematical steady-state modelling of Static Synchronous Compensator (STATCOM), which is the most widely used member of Flexible Alternating Current Transmission Systems (FACTS). STATCOM Power Injection Model (PIM), derived from one voltage source representation, is presented and analyzed in detailed. A program, Flexible Alternating Current Transmission Systems Power Flow (FACTSPF) in MATLAB has been developed which extends conventional Newton-Raphson (NR) algorithm based on the Power Injection Model (PIM).The STATCOM PIM and Current Injection Model (CIM) implemented in Power System Analysis Toolbox (PSAT) are incorporated in a 5-bus system. The results obtained from simulation of the 5-bus using FACTSPF are matched with those of PSAT in acceptable tolerance and thus confirms the robustness of the PIM. The PIM model represents a robust and feasible alternative when compared with Current Injection Model (CIM) implemented in Power System Analysis Toolbox (PSAT).
