In this research, Zero Injection Buses (ZIBs) were modeled to minimize the number of Phasor Measurements Units (PMUs) and ensure the full observability of power systems. To determine the operation of the proposed method, all ZIBs that are connected to each other and other buses were presented in models H, M, and D, each of which featured new observability constraints. The H set, is defi ned as the set of buses that are connected to a ZIB. Also, the M set is defi ned as the H set that is connected through ZIBs. The D set is defi ned as the M set that is connected through ZIBs to a common bus. To increase the assurance of complete power system observability in the method put forward in this work, conditions such as line outage, single PMU loss, and line or PMU exit were examined. To demonstrate the effi ciency of the approach, it was applied to 14, 30, 39, 57 and 118 IEEE test systems. The simulation results showed that the developed topologies enhanced network observability under a minimum number of PMUs.
