Power grid dispatching determining method and system

Abstract

The invention discloses a power grid dispatching determining method and system and relates to a power grid dispatching simulation method and system. Currently, power grid faults are frequently influenced by outside environments, and under extreme weather conditions, people can only wait for happening or developing of faults or accidents passively and cannot conduct prognosis and prevention on dispatching risks initiatively. A power grid structure and topological information are obtained from a power grid SCADA/EMS system, spare power automatic switching information is automatically generated, a repair schedule is combined, and the state information of a spare power automatic switching device is adjusted; combination with weather information can be achieved, the change of equipment outage probability is calculated, the load shedding amount is calculated specific to a threshold-crossing device and a power outage device, and early warning is given specific to large risk changes. According to the technical scheme, a dispatcher can find various risks in the operation process of a power grid in time.

AI Technical Summary

Benefits of technology

The present technology allows for accurate analysis of changing environmental conditions on an electrical power system's grids based upon their girdline models and topologies. This helps prevent damage from severe weathings or other factors affecting critical components such as equipment.

Problems solved by technology

The technical problem addressed in this patented technology relates to improving planning and reducing power loss during severe weathings caused by external environments like snow storms that affect power grids. Current methods involve manual adjustments made manually over time with limited data from remote sources. This approach has limitations due to its reliance solely relying upon measurements provided through an automatic monitoring system (AMT) which does not provide sufficient detail into how much outside influence could be happening when there were any issues before they happened.
