Phasor data concentrator placement in phasor measurement unit networks considering communication channel uncertainty and failure

Abstract One challenge in Wide Area Measurement System is to design a reliable network which assures data availability. The availability of Phasor Unit (PMU) networks depends on two factors: 1‐Reliable measurements depend performance PMUs and transmission branches, 2‐Reliable the reliability communication used transfer from Data Concentrators (PDCs) control centre. can be improved by choosing proper locations for PDCs. In this paper, novel approach PDC placement proposed based pre‐defined indices; observability Loss Of Expectation (LODE). method, probability regional networks' failure uncertainty all components are also included calculation these indices achieve more realistic results. To handle uncertainty, fuzzy membership functions obtained repair time rate components, Monte Carlo method presented evaluate both each possible PDCs' location. minimum LODE find best investigated three sample systems prove system efficacy.
