In　recent　years,　the　ultra-low-temperature　district　heating　(ULTDH)　systems　has　been　developed　to　further　reduce　the　heat　loss　in　the　district　heating　network.　In　this　paper,　on　the　basis　of　the　ULTDH　system,　a　double-　loop　booster　heat　pump　(DLBHP)　system　used　for　terminal　heating　is　proposed　to　improve　the　uniformity　of　temperature　difference　and　heat　transfer　efficiency.　The　building　heat　load　in　Beijing　was　simulated　using　DEST　software,　and　then　the　heating　simulation　model　of　the　DLBHP　was　established　through　the　TRNSYS　software　simulation　platform.　By　changing　the　various　control　strategies　on　the　heat　source　side　and　the　heat　sink　side,　the　optimization　of　the　operation　and　control　strategies　and　the　system　performance　were　analyzed.　The　simulation　results　indicate　that　compared　with　the　traditional　operation　modes,　the　system　average　COP　with　optimized　control　strategy　can　be　increased　by　up　to　9.24　%,　and　the　power　saving　during　the　heating　season　can　be　up　to　1389　kW　&　sdot;h.　It　can　satisfy　the　real-time　heat　load　demand　of　users,　and　has　a　large　energy-saving　potential　as　well　as　a　broad　market　application　prospect.
