Over the years, power system engineers have faced difficulties in achieving the best possible power flow. To guarantee the best possible power flow, the power system has integrated a number of techniques and technologies, from traditional to the usage of contemporary FACTS devices. Numerous power system issues, such as line overloading, voltage instability, transient instability, power system congestion, and others, can be mitigated by the FACTS devices. By altering its phase angle, a phase shifting transformer (PST), a FACTS device, can regulate power flow issues in a network. PST may reroute and redistribute power flow from overloaded lines to the less laden ones when it is put in the proper places on the power system. The power flow regulation method based on PST has good steady-state effect. It can improve the utilization efficiency of power grid assets and optimize the power flow distribution in a short time and at low cost.
