Abstract

This paper presents an improved imperialist competitive algorithm (ICA) for real power loss minimization using optimal VAR control in power system operation. In this paper, the modified imperialist competitive algorithm (MICA) is then offered for handling optimal reactive power dispatch (ORPD). The ORPD problem is formulated as a mixed integer, nonlinear optimization problem, which has both continuous and discrete control variables. The MICA is applied to ORPD problem on IEEE 30-bus, IEEE 57-bus and IEEE 118-bus test power systems for testing and validation purposes. Simulation numerical results indicate highly remarkable results achieved by proposed MICA algorithm compared to those reported in the literature.
