The　multi-port　energy　router　(ER)　is　an　effective　topology　for　integrating　train　traction　load,　AC　load,　the　energy　storage　system　and　photovoltaic(PV)　energy.　The　start　and　stop　process　of　urban　rail　transit　trains　and　the　access　of　distributed　energy　sources　to　rail　transit　ER　lead　to　serious　fluctuations　of　DC　bus　power,　so　it　is　necessary　to　route　energy　between　different　ports,　involving　multi-operating　modes,　while　seamless　switching　is　a　major　challenge.　In　this　paper,　a　hierarchical　coordinated　control　strategy　is　proposed　to　enable　the　multi-port　ER　to　operate　in　a　coordinated　fashion　under　the　conditions　of　train　parking,　acceleration,　constant　power　driving　and　deceleration,　and　to　switch　seamlessly　under　various　working　conditions.　The　energy　central　dispatching　layer　sends　working　condition　instructions　by　sampling　the　state　information　of　each　port,　while　the　microgrid　control　layer　adopts　centralized　control,　receiving　upper　working　condition　instructions　and　sending　drive　signals　to　the　local　control　layers　to　maintain　the　balanced　energy　flow　of　each　port.　In　the　local　control　layers,　the　PV　adopts　the　improved　perturbation　and　observation　method　of　power　control　(PC-P&O),　while　the　ES　system　adopts　voltage　loop　control　with　an　SOC　influence　factor,　voltage　loop　control　with　switching　factor　and　power　loop　control　according　to　the　different　working　conditions,　so　as　to　transmit　the　required　train　load　power　accurately　and　maintain　the　stability　of　the　DC　bus　voltage.　Finally,　the　effectiveness　of　the　proposed　hierarchical　coordination　control　is　verified　by　MATLAB/Simulink　simulations.
