A hierarchical analysis of phasor measurement unit placement optimization in transmission network

This paper presents a new phasor measurement unit (PMU) placement algorithm based on Hierarchical Analysis, a hybrid algorithm combining the breadth-first algorithm (BFA) and greedy algorithm. With the optimized number of PMU, the system is to maintain full network view during normal operation with and without conventional zero-injection effect. The IEEE standard 14-, 30-, 57- and the New England 39-bus test systems are investigated. Based on the comparison of the proposed method in this paper with other published methods, the proposed method has achieve good results with minimal PMU required and maximum system observability redundancy index (SORI).
