ORPD in highly stressed system-A comparative study using DE and BAT algorithm
Vijay B. Desle,  Kartik S. Pandya
Optimal reactive power dispatch (ORPD) is a complex optimization problem in which we try to “optimally” set the values of control variables like reactive power output of generators (generator bus voltages), tap ratios of transformers and reactive power output of shunt compensators like capacitors etc. to minimize the total transmission active power losses while satisfying a given set of constraints. In this paper solution of ORPD problem is done by stochastic population based search algorithms like differential evolution (DE) and BAT algorithms. The numerical results clearly show that DE algorithm gives better results required to reach global best solution. In order to illustrate the effectiveness of the proposed algorithm, it has been tested on highly stressed modified IEEE 300-bus test system.
Keywords- reactive power dispatch, optimization, active power loss, metaheuristics.
