Abstract :
We consider the problem of joint optimal placement of Phasor Measurement Units (PMU) and conventional measurements to ensure full observability in power systems. The problem is first formulated as a nonlinear integer programming problem and then recast in to an equivalent integer linear programming (ILP) problem by introducing auxiliary variables and constraints. The ensuing ILP problem is solved for the IEEE 14, 57 and 118 bus systems considering zero-injection buses. The results provide a far more economical solution to system observability compared to those obtained solely with PMU placement.
