“…The OpenPMU system was originally designed and developed at Queen's University Belfast (QUB), United Kingdom, to meet the needs of specific projects investigating anti-islanding detection and phase control of islanded generators [19], [31], [32]. The original motivation was to produce a low cost PMU optimized for real-time applications.…”

“…These two components are assessed independently, by fixing amplitude and varying phase, then fixing phase and varying amplitude. The OpenPMU's internal burden resistors are selected for measurements between 95 and 115 Vac, for its application in anti-islanding detection [32]. 115 Vac is also the upper limit of the Omicron test unit.…”

“…Islanding detection can be one of the other applications of PMUs. Although many researchers have already investigated the islanding detection techniques [49]- [51], there are recent improvements in this field using PMUs [11], [52]- [54]. They have concentrated on complete islanding detection techniques, based on phase and frequency measurements, but they have not studied the situation when only one phase of a multiphase microgrid is disconnected from the main grid.…”

To handle the increased level of real-time data exchange, this dissertation develops a supervisory control and data acquisition (SCADA) system that is equipped with a state estimation scheme from the real-time data. This system is verified on a specially developed laboratory-based test bed facility, as a hardware and software platform, to emulate the actual scenarios of a real hybrid power system with the highest level of similarities and capabilities to practical utility systems. It includes phasor measurements at hundreds of measurement points on the system. These measurements were obtained from especially developed laboratory based Phasor Measurement Unit (PMU) that is utilized in addition to existing commercially based PMU's. The developed vii PMU was used in conjunction with the interconnected system along with the commercial PMU's. The tested studies included a new technique for detecting the partially islanded micro grids in addition to several real-time techniques for synchronization and parameter identifications of hybrid systems.Moreover, due to numerous integration of renewable energy resources through DC microgrids, this dissertation performs several practical cases for improvement of interoperability of such systems. Moreover, increased number of small and dispersed generating stations and their need to connect fast and properly into the AC grids, urged this work to explore the challenges that arise in synchronization of generators to the grid and through introduction of a Dynamic Brake system to improve the process of connecting distributed generators to the power grid.Real time operation and control requires data communication security. A research effort in this dissertation was developed based on Trusted Sensing Base (TSB) process for data communication security. The innovative TSB approach improves the security aspect of the power grid as a cyber-physical system. It is based on available GPS synchronization technology and provides protection against confidentiality attacks in critical power system infrastructures.

The advancements in the field of wind turbine, solar photovoltaic (PV), fuel cell coupled with improved power electronics have increased reliability of renewable energy sources. The environmental benefits of these sources have forced the power industry to switch over for more distributed generations to meet the increasing load demand. Islanding in distribution system occurs when a portion of distribution system gets isolated from the rest of the grid and continues to supply the local load. Practically, all distributed generations (DG) are required to be disconnected immediately after the formation of island. It is done primarily to take care of safety of the operating personnel and to prevent power quality issues. Effective detection of islanding is an important area of concern. Prior to the integration of DG to the main electrical grid, each DG must be equipped with a suitable anti-islanding detection technique. In this paper, phasor measurement unit (PMU)based islanding detection technique is presented. The requirement of channel limits of PMUs is also incorporated, and significant results of industry and utility have been obtained. The study has been carried out using MATLAB/Simulink (version 2018a) creating several islanding and non-islanding cases in a PV integrated distribution grid.
