Abstract

This paper mainly concentrates in finding enhanced optimal solution for Multi-Objective Problem (MOP) with Thyristor Controller Series Compensator (TCSC) formulated using generation fuel cost, emission, and loss objectives with practical and operating constraints. Here, the optimal location is selected to enhance the system security in terms of minimizing line overloads and bus voltage violations under severe contingency. Cuckoo Search Algorithm (CSA) along with genetic algorithm cross over operation treated as Hybrid Cuckoo Search Algorithm (HCSA) is proposed to select best value as compared with existing evaluation algorithms. Optimizing multiple objectives simultaneously and selecting a best compromised solution as per the requirements of decision maker needs an application of MOP along with fuzzy decision making tool. The proposed Non-dominated Sorting Hybrid Cuckoo Search Algorithm (NSHCSA) with TCSC is tested on IEEE test system and corresponding results are analyzed. The OPF results obtained using proposed method is compared with the existing methods.

Keywords

Abstract

This paper proposed a novel load flow technique using Newton-Raphson (NR) polar form method with hybrid bus. In the former literature bus admittance matrix, YBus , is used for the computation of the load flow problems, that will take more number of iterations to converge the problem. To overcome this drawback, in this paper a novel NR polar form method using hybrid bus,HBus is proposed. The NR polar form load flow equations using HBus are derived. Standard IEEE test system and Indian utility systems are used to demonstrate the performance of the proposed approach. The results for NR power flow problem are physically interpreted on the IEEE-30 bus, 103 and 140 Indian utility bus systems with supporting numerical and graphical results and also validated against existing methods. The results using proposed approach show their superiority over existing approaches.
