Optimal Placement of PMUs Considering Sensitivity Constraints
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 2
Abstract
Phasor Measurement Unit (PMU), which is based on the GPS technique, is able to provide power engineers with immediate and precise measurements. By utilizing PMUs, the reliability and stability in power system are expected to be improved. This paper presents an optimization model to calculation of the minimum number of PMUs for complete observability of electrical power networks. In addition to the goal minimizing the number of PMUs, the sensitivity indicator is developed and introduced into the PMU placement in order to enhance the security of the power system networks. Bus sensitivity analysis based on Decoupled Power Flow method is studied. Also, discussed will be about the effect of zero injection busses on the problem results. The Integer Linear Programming (ILP) approach is implemented to solve this problem. Numerical studies are conducted on the IEEE 14, 30, 57 and 118 busses systems and the results are analyzed.
