It　is　a　practical　method　currently　to　do　network　loss　modification　by　incremental　transmission　losses　because　its　clear　physical　concept　and　simple　calculation　process　and　consistent　accuracy.　Now,　the　method　for　computing　incremental　transmission　losses　is　mostly　based　on　the　computing　of　power　flow.　In　the　practical　calculation,　the　unbalance　power　is　absorbed　by　the　buffer　machine.　This　paper　use　dispersed　generators　and　dispersed　load　to　absorb　the　unbalance　power,　and　based　on　these　experiments　to　research　the　influence　of　characteristics　of　generator　and　load　in　the　computation　of　the　incremental　transmission　losses-.　©　2011　IEEE.
