AB  - 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.
