LOOP POWER FLOW CONTROL BY SERIES CONTROLLABLE REACTANCES FOR OPTIMAL POWER FLOW MANAGEMENT

The electric power industry is currently un- dergoing an unprecedented reform worldwide. The dereg- ulation has introduced new opportunity for competition to reduce the cost and cut the price. The power flow control ability of series FACTS devices produces feasible solutions on the transmission congestion management and the trans- mission loss reduction in power systems with loops or par- allel paths. As a result, it contributes to the cost reduction of power industry. This paper presents an optimal power flow calculation by determining the control amount of series reactance which assuming the use of FACTS, in which the interior point method is selected to obtain the optimal solu- tion. A method to determine the effective assignment of se- ries controllable reactance is derived based on the sensitivity analysis.
