Optimal Allocations of FACTS Controllers for Economic Dispatch using Evolutionary Programming

摘要

In this paper, FACTS controllers are set to improve economic dispatch problem of electrical power system. In additional, the total transfer capability is used to indicate in parallel that FACTS controllers can be improved performance of power transfer ability in electrical power system. Evolutionary programming is used to determine optimal allocations of FACTS controllers. Two types of FACTS controller are set for using. The first type of FACTS controller is UPFC. The second type of FACTS controller is SVC. The optimal allocations are optimal parameter settings and optimal locations. The IEEE 30-bus system is used to demonstrate as test system. Test result shows that minimum, average and maximum fuel cost with FACTS controller are lower than those without FACTS controller. Moreover, total transfer capability with FACTS controller is closed to test result without FACT controller.
