Abstract
Reactive power plays crucial roles in power systems reliability and security. This study proposes the gravitational search algorithm is applied to Optimal Reactive Power Dispatch (ORPD) problem for real power loss minimization, voltage deviation minimization and voltage stability enhancement. ORPD is a mixed integer, non-linear optimization problem which includes both continuous and discrete control variables. The proposed algorithm is used to find the settings of control variables such as generator voltages, tap positions of tap changing transformers and reactive power output of the compensating devices. The proposed algorithm is evaluated on an IEEE 30-Bus Power System, simulation results show that the proposed approach converges to better solutions much faster than the earlier reported approaches in the literature.
