Hybrid Approach-Based Placement of Micro-Phasor Measurement Units in Active Distribution Networks

Abstract

The placement of monitoring devices like micro-Phasor Measurement Unit (μPMU), which works 24 hours, at all nodes in the distribution system, is contributing to temperature rise. This temperature rise can be reduced by placing the μPMUs at selected nodes. Therefore, this paper depicted a hybrid approach for μPMUs optimal placement in the distribution system. Optimal placement recognises the placement set containing the least number of μPMUs with optimum redundancy with which the phasors of voltage, as well as the current, can be calculated at each bus of the system. Constraints such as communication link unavailability, zero injection buses, and network reconfiguration are considered in the optimal μPMU placement formulation. The proposed approach overcomes the downside of Integer Linear Programming (ILP) which provides a single optimal location set. The proposed approach automatically assigned μPMUs to buses connected to radial buses, established by the degree of each bus, and reduces the computational concern. Provided algorithm efficiency is checked out with IEEE 40 bus feeder and IEEE 85 bus feeder system under Matlab/Simulink environment.
