This paper presents an application of improved particle sawrm optimization (IPSO) algorithm for solving the optimal reactive power dispatch (ORPD) problem in power systems and a case study for a practical 110kV power system of Shoutern Vietnam. The IPSO is an improvement of PSO with an integration of pseudo- gradient to enhance the search ability of PSO for application to large-scale systems. The proposed IPSO has been tested on the IEEE 30 bus system and the obtained results have indicated that the proposed method is enffective for the ORPD problem via result comparations with other methods. From the obtained results, the IPSO method has been also implemented to the ORPD problem for the 110 kV Southern Vietnam power system and the the obtained result is verified by the PSS/E program. The obtained results have indicated that the IPSO method is very effective for solving the large-scale practical systems.
