Early Warning Weather Hazard System for Power System Control

Abstract

Power systems and their primary components, mostly the transmission and distribution of overhead lines, substations, and other power facilities, are distributed in space and are exposed to various atmospheric and meteorological conditions. These conditions carry a certain level of risk for reliable electrical power delivery. Various atmospheric hazards endanger the operation of power systems, where the most significant are thunderstorms, wildfire events, and floods which can cause various ranges of disturbances, faults, and damages to the power grid, or even negatively affect the quality of life. By utilizing a weather monitoring and early warning system, it is possible to ensure a faster reaction against different weather-caused fault detections and elimination, to ensure a faster and more adequate preparation for fighting extreme weather events, while maintaining overhead line protection and fault elimination. Moreso, it is possible to bypass overhead lines that have the highest risk of unfavorable meteorological events and hazards, and reroute the energy, thus providing electricity to endangered areas in times of need while minimizing blackouts, and consequently, improving the quality of human life. This paper will present an analysis of the various risks of atmospheric phenomena, in the meteorological and climate context, and discuss various power system components, the power system control, operations, planning, and power quality. A concept with the main functionalities and data sources needed for the establishment of an early warning weather hazard system will be proposed. The proposed solution can be used as a utility function in power system control to mitigate risks to the power system due to atmospheric influences and ongoing climate change.

Research on the construction of a “full-chain” rapid response system for power emergencies

“…Satellite remote sensing technology makes up for the harsh working environment on site, the low efficiency of emergency response, the difficulty in reaching personnel, and the poor adaptability by ensuring the safe operation of the power system [ 32 ]. During the extreme weather warning period, the weather monitoring and early warning system are applied to the main risk points, supplemented by the above intelligent equipment to monitor the risk factors in real-time, which promotes the modernization of the monitoring and early warning capabilities of various disasters [ 33 ]. At the same time, the application of cloud-assisted big data to grasp the key disaster information in the disaster area [ 34 ].…”

The Causes and Forecasting of Icing Events on Power Transmission Lines in Southern China: A Review and Perspective

“…Scholars concur that the major difficulties in the construction of microterrain and micrometeorological numerical models are as follows: the lack of categorization of micrometeorological hazard analysis, the lack of uniform criteria for classifying the hazard level of icing events, and the lack of early warning criteria [40][41][42][43]. Therefore, many scholars have put forward bold analyses and hypotheses in the construction of micrometeorological monitoring systems and early warning system framework structures [44][45][46][47][48][49]. For example, Xu and Jin [50] used the MM5 model to study the impact of the topography of the Nanling Mountains on freezing rain weather in Hunan Province.…”

Overhead Power Line Damage Detection: An Innovative Approach Using Enhanced YOLOv8

“…Overhead power lines play a crucial role in power transmission systems, which are responsible for delivering electrical energy. However, these power lines face various natural and man-made threats, such as lightning strikes, wind and snow, birds, trees, pollution, and corrosion [1,2]. These threats can cause damage to the power lines, thereby affecting the safety and stability of power transmission.…”
