A comparative analysis of Optimal Power Flow techniques based on Equivalent Current Injection with conventional optimal power flow methods

This paper presents the comparative analysis of conventional optimal power flow methods - Newton Raphson method, Fast Decoupled Load Flow method with the Optimal Power Flow Techniques based on Equivalent Current Injection. With the use of Predictor Corrector Interior Point Algorithm (PCIPA), an Equivalent Current Injection based OPF models - Equivalent Current Injection Optimal Power Flow, Decoupled Equivalent Current Injection Optimal Power Flow, and Fast Decoupled Equivalent Current Injection Optimal Power Flow - are proposed and analyzed in this paper. The algorithm has been tested on IEEE 9 bus, 14 bus and 30 bus networks. The minimization problem based on equivalent current injection has been compared with the conventional Optimal Power Flow techniques. The result shows that, the previous ones converge nicely compared to conventional methods.
