TY - THES A1 - Osunde, Alex Osakpolor T1 - Medium and low voltage distribution grid network composition analysis and review for the North American and European networks N2 - The Distribution Network (DN) in Europe and North America today is witnessing a paradigm shift in operation from a conventional passive system where a top to bottom active and reactive power flow is maintained with a low level of monitoring to an active system where the power flow has become bi-directional with the influx of Distributed Generators (rooftop solar photovoltaic units, wind generating units, etc) in the low voltage (LV) and medium voltage (MV) networks. This implementation of DGs poses power quality problems as it causes stress on the existing voltage regulating strategy in the DN. To tackle this issue, utilities in both regions are integrating smart devices for controlling and monitoring the DN to guarantee power quality for their customers. The initial part of this paper focuses on individually and collectively studying the factors that determine how a network responds to voltage control. After which the impact and response of various load types and composition to voltage control were analysed. The difference between the MV and LV grid topology of the two regions was also highlighted. The second part of the project concentrates on the conventional and improved control devices implemented by utilities for achieving voltage stability. A case study of a representative network from both regions highlighting the advantages and challenges faced by adopting automated voltage regulation (AVR) was also carried out in this paper. In addition, the historical failure of the grids of both regions was examined to identify how the grid will react when a voltage control tool fails intending to suggest possible solutions.
