Binary cuckoo search based optimal PMU placement scheme for united Indian grid - A case study

N. V. Phanendra Babu, P. Suresh Babu, D.V.S.S. Sivasarma


The Phasor Measurement Unit (PMU) is becoming very effective device for power system as it produces synchronized parameters of power system. This measurement data helps us in monitoring, controlling and protecting the system effectively. To design a wide-area measurement system that could observe the complete system, a Binary Cuckoo Search (BCS) method is suggested in this paper. It also considers the system observability under line/PMU outage conditions. After testing the  methodology on some  benchmark systems, it has been applied on the Indian power grid. The results are then compared with the methods available in literature. This comparison has proven the proposed method as the best and accurate.
