Unified power flow controller (UPFC) is a standout amongst the best Flexible AC Transmission Systems (FACTS) for improving power system security. Despite that, the performance of UPFC can be brought out; it profoundly relies on the location and parameter set of this device in the system. The goal of the proposed approach is to limit the power loss and improves the loadability and voltage stability of the power transmission system. Here, Optimal Unified Power Flow Controller (OUPFC) in IEEE 14 and 57 bus systems is considered to control the dynamic power flows in the transmission line. The DC link storage capacitor in the UPFC system helps to stabilize the real power between the two voltage source converters. By analyzing the parameters, for instance, dynamic and reactive power, voltage and power loss of load buses, loadability of the system is improved. Moreover, with the aim of keeping up the stability of the power system, the optimal location and capacity of OUPFC system is analyzed by the Random Crow Search Optimization (RCSO). The optimal location and capacity of OUPFC achieved depends up on the random search behavior of CSO algorithm. To validate effectiveness of the proposed method, comparison is made with existing Particle Swarm Optimization (PSO) method. The performance of the OUPFC device is compared with other FACTS devices such as STATCOM and IPFC. [ABSTRACT FROM AUTHOR] |
