Study on evaluation system of meteorological hazards for power grid based on Cloud GIS

With the increment of the amount of meteorological hazard recently, storms and severe weather have become the leading cause of power outages. The present study aims to provide an alternative approach to identifying and evaluating the risk of meteorological hazards in the power system. An integrated Cloud-GIS and supporting technologies for the rapid muti-sensor data fusion and risk assessment are introduced in the paper, and the integrated evaluation system including four layers satisfies the meteorological hazards assessment requirement. Then a model is designed for assessing meteorological risk for power system depending on hazard-formative factors, vulnerability, and anti-disaster capacity. The case study has been employed in East China Grid, and the experimental results show that the new methodology offers accuracy risk level, with which the operators can establish and implement control measures to control these hazards.
