An effective binary integer linear programmed approach for optimal placement of PMUs in power systems
The Phasor Measuring Units provide synchronized measurements for monitoring and control of Power System State for Power System protection. The high PMU cost and installation cost are main reasons for minimizing the number of PMUs and their optimal placement should ensure Power System full Observability. This paper presents the investigation of Optimal placement of Phasor Measuring Units (PMU) and the use of reduced number of PMUs for ensuring Power system full observability. The Optimal PMU Placement (OPP) problem has been tackled considering different cases like with and without conventional measurements and zero injection buses. The OPP is considered for different contingencies such as single PMU or line outage to ensure full system observability. The PMU Channels, which limit the number of measurements at the installed bus is also taken into account in OPP formulation. MATLAB Simulations are carried out by Binary Integer Linear programming (BILP) method and tested on standard IEEE 14-bus, IEEE 30-bus, IEEE 57-bus and IEEE 118-bus systems. The results presented were compared with the recent literature and found the effectiveness of proposed method with regard to number of PMUs and execution time is appreciable.
