Optimal power flow with TCSC device using cuckoo optimization algorithm

This paper is applied Cuckoo Optimization Algorithm (COA) for the solution of the OPF problem of power system equipped with TCSC. The proposed approach has been examined and tested on the IEEE 30-bus system. The results presented in this paper demonstrate the potential of COA algorithm and show its effectiveness for solving the OPF problem with TCSC devices over the other evolutionary optimization techniques. | Journal of Science and Technology 54 (3A) (2016) 52-63 OPTIMAL POWER FLOW WITH TCSC DEVICE USING CUCKOO OPTIMIZATION ALGORITHM Duong Thanh Long*, Cao Van Tuan Department of Electrical Engineering, Industrial University of Hochiminh City, 12 Nguyen Van Bao Street, Ward 4, Go Vap District, Ho Chi Minh City * Email: duongthanhlong@iuh.edu.vn Received: 15 June 2016; Accepted for publication: 26 July 2016 ABSTRACT Optimal Power Flow (OPF) problem is an optimization tool through which secure and economic operating conditions of power system is obtained. In recent years, Flexible AC Transmission System (FACTS) devices, have led to the development of controllers that provide controllability and flexibility for power transmission. Series FACTS devices such as Thyristor controlled series compensators (TCSC), with its ability to directly control the power flow can be very effective to power system security. Thus, integration TCSC in the OPF is one of important current problems and is a suitable method for better utilization of the existing system. This paper is applied Cuckoo Optimization Algorithm (COA) for the solution of the OPF problem of power system equipped with TCSC. The proposed approach has been examined and tested on the IEEE 30-bus system. The results presented in this paper demonstrate the potential of COA algorithm and show its effectiveness for solving the OPF problem with TCSC devices over the other evolutionary optimization techniques. Keywords: Cuckoo optimization algorithm, OPF, FACTS, TCSC. 1. INTRODUCTION Power systems are becoming increasingly more complex due to the interconnection of regional system, deregulation of the overall electricity market and increased in power demand. Therefore, transmission networks require a substantial increase of power transfer which demands adequate available transfer capability to ensure all energy transactions. However, tight restrictions on the construction of new transmission lines due to increasingly difficult .
