System, method and apparatuses for distribution network reconfiguration and a tangible computer readable medium

Abstract

The present disclosure presents a system, method and apparatuses for distribution network reconfiguration, and a tangible computer readable medium. The system may comprise: at least one processor and at least one memory storing computer executable instructions. The at least one memory and the computer executable instructions configured to, with the at least one processor, cause the system to: detect an abnormal loading condition in a distribution network based on real-time measurements on the distribution network; and perform, in response to the detected abnormal loading condition resulted from excessive real power, a reconfiguration analysis process on the distribution network to obtain a reconfiguration plan for the detected abnormal loading condition. The reconfiguration analysis process is performed based on a heuristic logic method combining both depth first searching and breadth first searching. With embodiments of the present disclosure, it may detect an abnormal loading condition based on real-time measurements, and through the reconfiguration analysis process, it may obtain a practical and optimized reconfiguration plan so as to alleviate or even eliminate the detected abnormal loading condition in time, which may further prevent possible pre-matured failures of equipments and consequently save cost of equipment replacement and the power outage. Accordingly, the distribution network may operate with improved stability and reliability, and the operation cost may be reduced.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of power grid technology, and more particularly, to a system, method and apparatus for power distribution network reconfiguration and a tangible computer-readable medium. Background technique [0002] Every industry has a network associated with it. One such industry is the utility industry that manages the electrical grid. An electrical grid may include one or all of the following: generation, transmission, and distribution. Electricity may be generated by power stations such as coal-fired thermal power plants, nuclear power plants, and the like. For efficiency purposes, the generated electricity is boosted to a very high voltage (eg 345K volts) and transmitted on transmission lines. Transmission lines can carry electricity over long distances, such as across state lines or across national borders, until it reaches its wholesale customer, which can be a company with its own local distributio...

AI Technical Summary

Problems solved by technology

Heavy loads or overloads can lead to temperature rises in the insulation system and damage to insulation materials, and can lead to an increased risk of equipment failure, which in turn can lead to premature failures and further affect grid reliability

However, the current distribution management system (DMS) cannot obtain all the load information of the entire network (such as distribution transformer information), which means that the problem of heavy load or overload cannot be identified and solved in time
