1) The document discusses improving voltage stability and reactive power compensation in a transmission line using STATCOM (Static Synchronous Compensator) in MATLAB. 2) It simulates a three phase transmission line in MATLAB and observes the voltage drop when an additional load is added. 3) To mitigate this voltage drop, a STATCOM is used to dynamically inject reactive power and regulate the transmission voltage. The MATLAB model and results showing improved voltage stability with STATCOM are presented and analyzed.
