Abstract:

Shunt Capacitors in power systems are generally used for reactive power compensation. The optimal location ofcapacitors plays a vital role for reducing real power losses in distribution system. This paper considers the problem of optimal allocation and sizing of capacitors in a radial distribution network. A power loss  sensitivity technique is used to determine the optimal location and sizing of capacitors in distribution system. The objective function is formulated to reduce real power losses and to improve voltage profile of the system. The performance of the proposed method has been tested on IEEE 69- bus standard system. Test results are also compared with other optimization techniques and found that the proposed method is more effective and has higher capability in finding optimum solution .
