Title:CityIntegratedEnergyNetwork:UnifiedForwardandBackwardEnergyFlowCalculationMethod
Abstract:
Therapidurbanizationandtheincreasingenergydemandsincitieshaveposedsignificantchallengesforsustainableenergymanagement.Acomprehensiveunderstandingofenergyflowswithinacity'sintegratedenergynetworkiscrucialforoptimizingenergyutilization,identifyingefficiencyimprovements,andreducingenvironmentalimpact.Thispaperfocusesonthedevelopmentofaunifiedforwardandbackwardenergyflowcalculationmethodforcitycomprehensiveenergynetworks,aimingtoprovideaholisticperspectiveonenergyflowsandfacilitateeffectiveenergymanagementstrategies.
1.Introduction:
Citiesarecomplexsystemswithmultipleinterconnectedenergysectors,includingelectricity,heating,cooling,andtransportation.Acity'sintegratedenergynetworkrepresentsthemutualinteractionandinterdependenceofthesesectors,necessitatingaholisticapproachtoenergymodeling.Traditionalenergyflowanalysisoftenfocusesonasinglesector,neglectingtheinfluenceandfeedbackbetweendifferentsectors.Therefore,aunifiedforwardandbackwardenergyflowcalculationmethodisrequiredtocapturesuchinterdependenciesandprovideacomprehensiveunderstandingofenergyutilizationwithinacity.
2.Methodology:
Theproposedmethodintegratesbothforwardandbackwardenergyflowcalculationswithinacity'scomprehensiveenergynetwork.Theforwardcalculationanalyzestheenergyflowfromtheprimaryenergysourcestotheend-usesectors,consideringboththedirectandindirectenergyconsumption.Thisstepinvolvesdatacollection,energybalancecalculation,andsector-wiseenergyflowanalysis.
Thebackwardcalculation,ontheotherhand,dealswiththefeedbackloopfromend-usesectorsbacktotheprimaryenergysources.Itquantifiestheenergylossesandemissionsassociatedwiththeenergyconversionprocessesanddistributionsystemsandconsidersthepotentialforenergyrecoveryandreuse.Thebackwardcalculationassistsinidentifyingenergylossesandinefficienciesintheenergysystems,enablingtargetedinterventionstoimproveoverallenergyperformance.
