This document summarizes a study on using STATCOM and UPFC devices to control power flow in a distribution system. It presents the mathematical models of STATCOM and UPFC, including their control design procedures. Simulation results show that STATCOM effectively regulates local reactive power load and UPFC controls real power flow by varying the phase angle of injected voltage. The study demonstrates how FACTS devices like STATCOM and UPFC can improve power flow control in distribution systems.
