This　paper　proposes　a　flexible　interconnection　device　control　strategy.　It　takes　transformer　power　loss　into　account　to　solve　the　problems　of　voltage　overrun,　station　load　imbalance,　and　unbalanced　transformer　capacity　allocation　that　occur　after　the　large-scale　connection　of　distributed　power　sources　into　the　low-voltage　distribution　network　to　realize　the　mutual　aid　of　active　power　and　load　balancing　between　interconnected　stations.　Firstly,　the　VSC　control　strategy　with　capacitor　current　feedback　active　damping　link　is　introduced　to　accurately　execute　the　power　commands　and　maintain　the　DC　bus　voltage　stability.　Then,　the　load　regulation　strategy　with　transformer　power　loss　is　proposed　to　generate　the　power　commands　of　the　flexible　interconnection　device.　Finally,　the　simulation　results　show　that　the　control　strategy　of　the　flexible　interconnection　device　with　transformer　power　loss　mentioned　in　this　paper　can　flexibly　control　the　power　transmitted　by　each　port　and　maintain　the　bus　voltage　stability.　The　simulation　results　show　that　the　flexible　interconnection　device　control　strategy　proposed　in　this　paper,　which　takes　into　account　the　transformer　power　loss,　can　flexibly　control　the　transmission　power　at　each　port　to　keep　the　bus　voltage　stable.　Moreover,　it　can　effectively　reduce　system　loss　compared　with　the　traditional　load　regulation　strategy.　©　2024　Institute　of　Physics　Publishing.　All　rights　reserved.
