Increase power transfer capability and controlling line power flow in power system installed the FACTS

This paper presents possibility to increase power system capability and controlling line power flow in power system with FACTS controllers. FACTS enhance power system performance, improve quality of supply and also provide an optimal utilization of existing resources. Various FACTS controllers devices, especially SVC and STATCOM, enable load flow on parallel circuits to be optimized and controlled, with a minimum of power wheeling, the best possible utilization of line, and a minimizing of overall system losses at the same time. The objectives were to determine the power transfer capability in power system, identify means of increasing the transfer limit, and test the potential application of FACTS devices. The paper describes the analytical approach, computational tools and simulations models. (6 pages)
