计及可入网电动汽车的阻塞管理研究摘要随着电动汽车的规模性发展，主动配电网中电动汽车的渗透率逐渐提高，它拥有随时可以控制充电及放电时间转移的功能，让电动汽车充电、放电时间的规律成为左右主动配电网负荷峰值的关键要素之一。在目前政府对电力市场采取鼓励政策的环境下，电动汽车群充电展现了较好的灵活性。因此在此基础上，本文针对电动汽车在主动配电网中的充电柔性，开展了当前电力市场环境中利用市场机制管理控制电动汽车充电负荷的研究，以达到消除电力负荷尖峰及配电系统拥堵的目的。针对电动汽车不同的充电活动所需的不同功率，本文提出了电动汽车充电、放电负荷的一种运算方式，即是蒙特卡洛模拟抽样起始荷电状态、起始充电时间来得到充放电中可控容量的曲线，对我国将来电动汽车充电、放电负荷的整体态势开展了分析研究。利用Matlab软件来改善程序，分别分析了传统模式与电动汽车参与阻塞管理的情况下，消除输电线路阻塞的方法与可行性。在传统模式下，可以通过中断某节点的负荷和调节分布式发电机两种方法来消除阻塞；在电动汽车参与阻塞管理时，建立计及电价的基于V2G的输电阻塞管理模型，将电动汽车作为分布式储能单元，从负载端调节并通过发电机的配合调整以消除输电阻塞。通过matpower潮流计算成程序，计算并比较使用三种方法消除阻塞的费用。最后以IEEE14节点为例，证明该文的阻塞管理模型可实现降低主动配电网的阻塞效应，有利于提高电网运行的安全性和经济性。关键词：电力市场，阻塞管理，电动汽车，V2GABSTRACTWiththelarge-scaledevelopmentofelectricvehicles,thepenetrationrateofelectricvehiclesintheactivedistributionnetworkisgraduallyincreasing.Ithasthefunctionofcontrollingthecharginganddischargingtimetransferatanytime,andtheregularityofcharginganddischargingtimeofelectricvehiclesbecomesanactivedistributionnetwork.Oneofthekeyelementsofloadpeaks.Inthecurrentenvironmentwherethegovernmenthasadoptedanincentivepolicyfortheelectricitymarket,thechargingofelectricvehiclegroupshasshowngreaterflexibility.Therefore,basedonthis,thisarticleaimsatthechargingflexibilityofelectricvehiclesinactivedistributionnetworks,andconductsresearchontheuseofmarketmechanismstomanageandcontrolthechargingloadofelectricvehiclesinthecurrentelectricitymarketenvironmentinordertoeliminatepowerloadspikesandpowersystemcongestion.thegoalof.Aimingatthedifferentpowerrequiredfordifferentchargingactivitiesofelectricvehicles,thispaperproposesacalculationmethodforthecharginganddischargingloadsofelectricvehicles,thatis,theinitialstateofchargeandinitialchargingtimeofMonteCarlosimulationtoobtainthechargeanddischarge.ThecurveofcontrollablecapacityhascarriedontheanalysisandresearchtotheoverallsituationofelectricvehiclecharginganddischargingloadinChinainthefuture.Matlabsoftwarewasusedtoimprovetheprogram,andthemethodandfeasibilityofeliminatingtheblockageofthetransmissionlineundertheconditionthatthetraditionalmodeandtheelectricvehicleparticipatedinthecongestionmanagementwereanalyzed.Inthetraditionalmode,blockingcanbeeliminatedbyinterruptingtheloadofanodeandadjustingdistributedgenerators.Whenanelectricvehicleparticipatesinblockingmanagement,aV2G-basedpowertransmissioncongestionmanagementmodelthattakesintoaccountthepriceisestablished,andtheelectricvehicleistreatedasThedistributedenergystorageunitisadjustedfromtheloadsideandadjustedbythegenerator'sfittoeliminatetheresistanceplug.Throughmatpowerpowerflowcalculations,calculateandcomparetheuseofthreemethodstoeliminatethecostofblocking.FinallytakingtheIEEE14nodeasanexample,itisprovedthatthecongestionmanagementmodelofthispapercanreducetheblockingeffectoftheactivedistr...
