Design and Implementation of a Fast Load Reversal Method for Distribution Networks
Conventional distribution network feeders commonly suffer long-time heavy overload state,which accelerates the aging of feeder components,reduces the service life of feeders,increases the probability of feeder faults,and thus affects power supply reliability of distribution networks.In view of this,through introducing the current prevailing microservice architecture,the present study proposes a load reversal method which is based on load sharing and maximum reserve capacity of interconnection lines and can achieve rapid load reversal in the event of heavy overload encountered by distribution network feeders.Based on the application architecture of microservices,the heavy overload reversal function is decoupled into various functional modules.And by combining design concepts such as the Cloud Origin Twelve Factors and Conway's Law,the distribution network load reversal business is divided into regional load calculation microservices,overload monitoring microservices,load reversal microservices,and operation ticket execution microservices.Finally based on a certain cloud platform,the load reversal function verification is carried out.The verification results show that the method based on load sharing and maximum reserve capacity of connecting lines can quickly reverse closer loads,avoid unnecessary user power outages,and also improve user electricity efficiency.
