To　meet　the　application　requirements　of　flexible　power　flow　control　in　local　power　systems　across　voltage　levels,　the　PFCT　circuit　topology　and　its　power　flow　control　strategy　are　studied.　A　PFCT　circuit　topology　and　its　equivalent　model　are　proposed.　The　mathematical　modeling　for　the　series　and　parallel　components　of　the　PFCT　are　established,　along　with　corresponding　control　strategies.　Flexible　control　of　power　flow　transmission　along　the　line　is　accomplished　by　cross-decoupling　power　flow　control　and　feedforward　decoupling　control.　A　simulation　model　was　built　by　using　the　MATLAB/Simulink　platform　to　analyze　and　validate　the　PFCT＇s　control　of　power　flow　transmission　across　voltage　levels　in　a　typical　local　power　system.　A　prototype　was　constructed　to　validate　further　the　correctness　and　feasibility　of　the　proposed　mathematical　models　and　control　strategies.　©　2025　Institute　of　Physics　Publishing.　All　rights　reserved.
