A simplified and effective approach of PMU placement for large-scale distribution systems is presented in this paper. The proposed algorithm finds an optimal solution to placement problem by decomposition of network into two sub-networks. Since the problem size is reduced due to splitting into two stages. this decomposition reduces the …
