The increasing integration of intermittent renewable generation, especially at the distribution level, necessitates advanced planning and optimisation methodologies contingent on the knowledge of the admittance matrix, capturing the topology and line parameters of an electric network. However, a reliable estimate of the admittance matrix may either be missing or quickly become obsolete for temporally varying grids. In this work, we propose a data-driven identification method utilising voltage and current measurements collected from micro-PMUs. More precisely, we first present a maximum likelihood approach and then move towards a Bayesian framework, leveraging the principles of maximum a posteriori estimation. In contrast with most existing contributions, our approach not only factors in measurement noise on both voltage and current data, but is also capable of exploiting available a priori information such as sparsity patterns and known line admittances. Simulations conducted on benchmark cases demonstrate that, compared to other algorithms, our method can achieve greater accuracy.

“…By developing a dynamic model of the transmission line, the expected voltages at any locations of the transmission line either on the sources side or load sides can be predicted. The resistance of the conductors is the primary sources of transmission line losses [16]. As the current attempt to overwhelm the ohmic resistance of the line, useless heat is formed in the result of power dissipation.According to [17], AC transmission networks and distribution lines are purely reactive network.…”

<span>Transmission line is one of the important elements in the process of power transfer from the source of generation to the consumer. In order to analyze the performance of a transmission line, it has to be represented by an equivalent model with suitable circuit parameters at a per phase basis. The line models are used to measure voltages, currents and the amount of power flow depending on the line length. Transmission line performance is determined by the voltage regulation and its efficiency under their normal operating conditions. In this study, a systematic approach was developed in order to assists the lecturers in teaching this important topic to the students despite so many complicated mathematical equations involved in the calculation. With the aid of Graphical User Interface (GUI), the performance of transmission line can be determined and monitored due to the change of line parameters. The results obtained could assist the lecturers in delivering the concept of engineering in a more systematic approach. On top of that, it could also assist the power system utility in planning the transmission line that needed to be installed in the system.</span>

“…Therefore appropriate modeling and care is of paramount while designing and erecting a high voltage transmission system. The subsequent performance of the transmission depends on the kind of transmission model used in the system [3]. Instability on transmission line are caused by various factors such as sag, aerodynamic drag, wind, tension, ice loading, conductor size, insulators, line span e.t.c.…”

This paper examines the effects of wind environment on high voltage transmission lines span. Proper analysis of wind and its effects is important on high voltage transmission lines for the purpose of continuity and quality of electrical services. Strong wind has the potential of causing unexpected damages to conductors and thus erupting power transmission of the system. Various literatures on wind effects on high voltage transmission lines were reviewed. The various effects of wind environment on high voltage transmission lines span as well as possible solutions to these effects were examined.
