Abstract: Optimal Placement of Automatic Voltage Regulator (AVR) in distribution system with Modified Cuckoo search algorithm is proposed. The optimal Location of AVR's in distribution network has been achieved using the voltage stability index values at each node and the minimum total active power loss that is obtained for a particular location of the AVR at a node. The Tap-settings of the AVR has been descided based on the optimization of objective function subjected to constraints using Modified Cuckoo Search Algorithm. The proposed method has been tested on standard 15-node, 33-node and 69-node distribution systems and the results obtained are better than the existing methods.
