Optimal Power Flow With Interline Power Flow Controller Using Modified Bat Algorithm

Normally, economic load dispatch problem schedules the generators in such a way that, the lowest cost of generation should be utilized properly and the total system load along with the transmission power losses are supplied. Because of the development of the Flexible AC Transmission System (FACTS) controllers, the power transfer capability of the power system is increased and the transmission lines are operating nearer to thermal limits. In power system economic aspects, it is necessary to minimize the generation fuel cost to increase the net saving of the power system. In this paper, the modified BAT algorithm is developed to solve OPF problem by considering conventional fuel cost as an objective. This problem is solved while satisfying equality and in-equality constraints. The effect of IPFC is analyzed in on standard IEEE-30 bus system with supporting numerical results.
