Calculation and Reduction Technology of Distribution Network Line Loss under Distributed Power Supply Access
This article mainly explores the calculation method of line loss and measures to reduce line loss when distributed photovoltaic power sources are connected to the distribution network.The forward and backward substitution method is used to calculate the power loss generated by each section of the line from the end of the line to the power supply end,and the sum result is the power supply end power.Recalculate the voltage drop for each section based on the known power supply and rated voltage.Loop back and forward calculation until the power deviation of the node is within the allowable range,then the power loss of the line can be obtained.Introduced loss reduction technologies from both technical and management perspectives.Technical loss reduction includes selecting reasonable access locations and capacities,as well as installing energy storage devices such as supercapacitors;Management loss reduction includes implementing scientific economic incentives,and adjusting peak and valley electricity prices reasonably.
