Coordinated Control Study on Flexible Interconnection of Distribution Station Areas Considering Transformer Power Losses
摘要
Abstract
Aiming at the problems of voltage overrun,unbalanced load in station areas,unbalanced transformer capacity distribution and other problems that occur in the traditional low-voltage distribution network after the large-scale access to low-voltage stations by distributed generator,the power regulation capability of flexible interconnection devices is utilized to construct multi-station interconnections,and a load regulation strategy taking into account the power loss of transformers is proposed to realize the mutual aid of active power and load balancing among the interconnected distribution stations areas.Firstly,the control strategy of the flexible interconnection device with the capacitor current feedback active damping link is introduced to lay the foundation for ensuring the effective implementation of the subsequent load regulation strategy.Then,the load regulation strategy taking into account the transformer power loss is proposed to generate the power command of the flexible interconnection device.Finally,the simulation results show that the proposed strategy can flexibly control the transmission power of the ports and keep the DC voltage at the same time,and can effectively reduce the system loss compared with the traditional load control strategy.关键词
