Abstract—To better performance and real time observability to Iraq networks (400KV, 132KV) by setting up PMU in different sites of the networks. In this paper the Power system observability analysis and the rules with phasor measurement unit (PMU) are presented. it is unnecessary as well as uneconomical to status PMU in each bus, therefore there are various algorithms: Depth First Search, a graph-theoretic procedure, Annealing Method, Rec. spanning Tree, Direct spanning Tree, Dir (N-1) Spanning Tree, Binary integer programming and Linear programming, are applied to find optimal number and optimal placement of PMU to obtain fully observability of the system in two cases: first case each bus can be seen at least one time from PMU and second case each bus can be seen at least two times from PMU, to networks of systems: IEEE 9-bus, IEEE 14-bus, IEEE 24-bus. Simulation results proved amongst optimal solutions obtained from these algorithms, it be by use binary integer programming therefore, applied it to obtained optimal number and optimal placement of PMU to Iraq networks (400KV, 132KV) to observability whole system for these two cases.
Index Terms—Binary integer programming, observability, optimal PMU placement (OPP), PMU.
