Congestion management using FACTS

What is it about?

that IPFC controls the power flows in the network without generation rescheduling or topological changes and thus improves the performance of the system. It is found that the benefit achieved in the expected security cost due to the installation of IPFC is greater than the annual investment cost of the device. Independent system operator (ISO) cannot achieve minimum total system cost by merely rescheduling generators. Instead of rescheduling, FACTS devices can be used for compensation by achieving minimum cost. IPFC can be used to compensate the congested lines and transfer cheaper power from generators to consumers.

Why is it important?

Instead of using multiple FATCS devices, if a single FACTS Device like IPFC which itself can compensate a several transmission lines is used, then in addition to the facility for independently controlled reactive (series) compensation of each individual line, it provides a capability to directly transfer real power between the compensated lines.Hence an attempt has been made in this paper to incorporate IPFC for relieving congestion in a deregulated environment
