图1为本公开能源互联网系统的一些实施例的结构示意图。该能源互联网系统包括交流侧能源路由转换设备110、直流侧能源路由转换设备120和多个能源设备130。
交流侧能源路由转换设备110能够将交流电转换为直流电，还能够实现能量信息采集和信息路由的功能。直流侧能源路由转换设备120能够将一个直流电压值转换为另一个直流电压值，以及实现能量信息采集和信息路由的功能。
交流侧能源路由转换设备110包括多个第一路由端，直流侧能源路由转换设备120包括多个第二路由端，第一路由端数量与第二路由端数量相同，每个第二路由端通过相应的直流母线与对应的第一路由端连接。其中，在图1中仅示出两个第一路由端，两个第二路由端，即对应二维度能源互联网系统，本领域的技术人员应当理解，还可以根据实际情况设置更多维度的能源互联网系统。
能源设备130可以为储能设备、用电设备或发电设备等，能源设备130可以通过相应的第一交直流转换器或第一直流转换器连接至直流母线上，例如，如图2所示，若能源设备130为储能设备，则可以通过DC/DC转换器连接到直流母线上；若能源设备130为交流用电设备，则通过DC/AC转换器连接到直流母线上，若能源设备130 为厨房电器等直流用电设备，则通过DC/DC转换器连接到直流母线上，其中，若能源设备130为照明等低压直流用电设备，还可以再次通过DC/DC转换器接入低压母线，保证低压直流用电的安全；若能源设备130为发电设备，如分布式风电机组，则通过AC/DC转换器连接到直流母线上，若为光伏电池组件，则通过DC/DC转换器连接至直流母线上，当然，发电设备还可以为其他清洁能源，通过相应的DC/DC转换器或AC/DC转换器连接至直流母线上。其中，各级母线电压值可以被定义为其他任何直流电压等级。
交流侧能源路由转换设备110、直流侧能源路由转换设备120与多个能源设备130之间的信息交互可以采用无主通讯。
在上述实施例中，交流侧能源路由转换设备110和直流侧能源路由转换设备120采集各能源设备130的能量信息，基于能量平衡约束条件，对各个能源设备130的能量进行调节，从而实现能源互联网系统能量交换平衡运行。

图4为本公开能源互联网系统的又一些实施例的结构示意图。交流侧能源路由转换设备为交流侧能源路由器410，直流侧能源路由转换设备为直流侧能源路由器420，能源路由器可以从能源角度，维持能源互联网系统电能供需平衡，自主路由能源传输方向，实现能量自由分配。该实施例以三维能源互联网系统为例进行说明。
交流侧能源路由器410的三个第一路由端分别与直流侧能源路由器420的三个第二路由端通过直流母线连接，其中，用电设备430若为直流负载，则可以通过DC/DC转换器接入到直流母线的α4节点，用电设备430若为交流负载，则可以通过DC/AC转换器接入到直流母线的α3节点，其中，用电设备430具有行为特征，即能够实时采 集自身的电压参数、电流参数、功率参数和电量参数等能量信息，以及运行状态参数，并对各参数进行上报，同时能够接收系统下发的指令。储能设备440可以通过DC/DC转换器连接到直流母线的α2节点，发电设备450可以通过DC/DC转换器连接到直流母线的α1节点，其中，图中直流母线的β1，β2，β3，β4，γ1，γ2，γ3以及γ4节点等也可以接入对应的能源设备，图4未示出。

在一些实施例中，交流侧能源路由器410采集用电设备430、储能设备440、发电设备450和交流配电网设备460的能量信息，基于能量平衡约束条件分别对用电设备430、储能设备440、发电设备450和交流配电网设备460进行能量调节。可以忽略系统的转换损耗及其他损耗，并且规定一个能量流动方向的前提下，在直流母线连接点应存在能量平衡关系，用电设备430、储能设备440、发电设备450和交流配电网设备460可根据交流侧能源路由器410的自主控制需要参与自主调度响应。
能量平衡约束条件包括：用电设备430、储能设备440、发电设备450和交流配电网设备460的电压参数、电流参数、功率参数和电量参数分别在各自相应的阈值范围内，用电设备430、储能设备440、发电设备450和交流配电网设备460的功率之和为0，电流之和也为0。另外，对于三维能源互联网系统，三个直流母线上的功率之和以及电流之和均为0。
在一些实施例中，直流侧能源路由器420采集用电设备430、储能设备440、发电设备450和直流配电网设备470的能量信息，基于能量平衡约束条件分别对用电设备430、储能设备440、发电设备450和直流配电网设备470进行能量调节，其调节方式与上一实施例相似。
在上述实施例中，通过三维能源互联网系统中各部件的连接关系，以及信息交互，解决了能源互联网系统架构下，发电设备、储能设备、用电设备、配电网设备的自主控制与稳定运行，以及经济调度问题。
另外，原有维度能源互联网系统中若增加一维度的能源互联网系统，由于路由器能够及时进行能量调度，各设备能够自行响应调整用电需求，可以使得系统快速达到 能量平衡，保证系统可靠安全运行，减小系统环流问题。
图5为本公开能源互联网系统的又一些实施例的结构示意图。该实施例以三维能源互联网系统为例进行说明，其中，交流侧能源路由转换设备包括三个第三交直流转换器(AC/DC)510、511和512，直流侧能源路由转换设备包括三个第三直流转换器(DC/DC)520、521和522，其中，第三交直流转换器510的第一端、第三交直流转换器511的第一端和第三交直流转换器512的第一端相连接在PC节点，第三直流转换器520的第一端、第三直流转换器521的第一端和第三直流转换器522的第一端相连接在DPC节点。每一个第三交直流转换器的第二端作为第一路由端，每个第三直流转换器的第二端作为第二路由端，即第三交直流转换器510的第二端通过直流母线与第三直流转换器520的第二端连接，第三交直流转换器511的第二端通过直流母线与第三直流转换器521的第二端连接，第三交直流转换器512的第二端通过直流母线与第三直流转换器522的第二端连接。交流配电网设备460连接至PC节点，直流配电设备470连接至DPC节点，用电设备430、储能设备440和发电设备450与图4中的连接关系相一致。
在该实施例中，第三交直流转换器510、511和512以及第三直流转换器520、521和522可以自带传感器、计量元件实现各部件的运行状态及能量监测，也可以通过外部附加计量电表实现，从而实现各维度之间、以及各能源设备、配电网设备之间的能量平衡。
在一些实施例中，各转换器之间可以采用无主的通信方式。由于多维度系统采用交流、直流互联的组网方式和无主调度形式，决定了系统中各单维度系统间是平等、并行的架构。方便分布式系统的“即插即用”，同时，实现能量的自由分配、协同互补和一体化均衡运行。

(u,i,p,q) load_min<(u,i,p,q) load<(u,i,p,q) load_max；
其中，(u,i,p,q) gene、(u,i,p,q) bat、(u,i,p,q) grid、(u,i,p,q) load分别为发电设备、储能设备、配电网设备和用电设备稳定运行时的电压参数u、电流参数i、功率参数p和电量参数q值，(u,i,p,q) gene_min、(u,i,p,q) bat_min、(u,i,p,q) grid_min、(u,i,p,q) load_min分别为发电设备、储能设备、配电网设备和用电设备的电压参数u、电流参数i、功率参数p和电量参数q的最小值，(u,i,p,q) gene_max、(u,i,p,q) bat_max、(u,i,p,q) grid_max、(u,i,p,q) load_max分别为发电设备、储能设备、配电网设备和用电设备的电压参数u、电流参数i、功率参数p和电量参数q的最大值。

即配电网设备的功率参数与电压参数、电流参数和功率因数参数相关。
其中，对于单维度能源互联网系统，系统能量平衡应该满足u dc＝u dc_ref，其中，u dc为直流母线电压，u dc_ref为直流母线参考电压；发电设备、储能设备、配电网设备和用电设备的功率参数p之和为0，即p grid+p gene+p bat+p load＝0；同时发电设备、储能设备、配电网设备和用电设备的电流参数i之和为0，即i grid_dc+i gene_dc+i bat_dc+i load_dc＝0。另外，系统能量平衡还满足u dc＝u gene＝u bat，其中，u gene为发电设备电压，u bat为储能设备电压。
当系统能量发生变化时，系统中发电设备、储能设备、配电网设备、用电设备等各部件均可参与能量调节。能量发生变化后系统仍然保持稳定运行，即能量平衡、母线电压恒稳。
对于多维度能源互联网系统运行时，若光照突然增强，新能源发电突然增大，储能设备、电网设备、用电设备等各部件均超出自身允许冗余能力范围，无法消纳时多余能量时必须进行限功率运行，其中，离网时电网允许冗余能力为0。如图4、5所示，多维系统运行时，系统α出现前述情况，可将多余能量自由分配到系统β或系统γ予以消纳，多个系统之间相互协同。同样，若单维系统能量不足时，可从与母线相连的其余系统自由获取剩余能量。
各直流母线上的功率之和为0，即各维度能源互联网系统功率之和为0，需满足p dc_dg1+p dc_dg2+...+p dc_dgn＝0，其中，p dc_dgn＝f n(f n(f 1(v,i,t,s),f 2(v,i,t,s)...),f n(v,i,T,soc),f n(f 1(v,i),f 2(v,i)...))，p dc_dgn是各维系统根据自身发电、储能、用电系统构建的能量实时函数，是多维系统之间的直接交互调度对象。同时，各直流母线的电流之和为0，即各维度能源互联网系统电流之和为0，需满足i dc_dg1+i dc_dg2+...+i dc_dgn＝0。
由于系统所涉发电设备、储能设备、配电网设备、用电设备的负荷均应在自身允许冗余能力范围内，每一个维度内的发电设备、储能设备、用电设备和配电网设备的电压参数u、电流参数i、功率参数p和电量参数q应满足以下条件：
(u,i,p,q) gene_n_min<(u,i,p,q) gene_n<(u,i,p,q) gene_n_max；
(u,i,p,q) bat_n_min<(u,i,p,q) bat_n<(u,i,p,q) bat_n_max；
(u,i,p,q) grid_n_min<(u,i,p,q) grid_n<(u,i,p,q) grid_n_max；
(u,i,p,q) load_n_min<(u,i,p,q) load_n<(u,i,p,q) load_n_max；
其中，(u,i,p,q) gene_n、(u,i,p,q) bat_n、(u,i,p,q) grid_n、(u,i,p,q) load_n分别为发电设备、储能设备、配电网设备和用电设备稳定运行时在同一个维度内的电压参数u、电流参数i、功率参数p和电量参数q值，(u,i,p,q) gene_n_min、(u,i,p,q) bat_n_min、(u,i,p,q) grid_n_min、(u,i,p,q) load_n_min分别为发电设备、储能设备、配电网设备和用电设备在同一个维度内的电压参数u、电流参数i、功率参数p和电量参数q的最小值，(u,i,p,q) gene_n_max、(u,i,p,q) bat_n_max、(u,i,p,q) grid_n_max、(u,i,p,q) load_n_max分别为发电设备、储能设备、配电网设备和用电设备在同一个维度内的电压参数u、电流参数i、功率参数p和电量参数q的最大值。
同时，系统能量平衡应该满足u dc＝u dc_ref，其中，u dc为直流母线电压，u dc_ref为直流母线参考电压；发电设备、储能设备、配电网设备和用电设备在同一个维度内的功率参数p之和为0，即p grid_n+p gene_n+p bat_n+p load_n＝0；同时发电设备、储能设备、配电网设备和用电设备在同一个维度内的电流参数i之和为0，即i grid_n_dc+i gene_n_dc+i bat_n_dc+i load_n_dc＝0。另外，系统能量平衡还满足u dc＝u gene_n＝u bat_n，其中，u gene_n为发电设备在某一维度内的电压，u bat为储能设备在某一维度内的电压。
多维系统正常运行时，其母线电压恒定，其中某一单维系统切入或切出不影响系统的正常运行。多维系统中各单维系统是并行的、独立的具有自主控制能力的个体，相互之间实现无主通讯，能量数据可实时参与控制调度。
在一个具体实施例中，对于单维度能源互联网系统，系统中发电设备、储能设备、配电网设备、用电设备的额定功率可以采用1:1:1:3的极限架构配置。具体如下：
发电设备为光伏发电，额定发电功率为5kW；储能设备额定充放电功率为5kW，容量为20kwh(可放电4小时)；电网侧额定工作功率为5kW；用电设备额定用电功率为15kW。
能源互联网系统满负荷运行时，发电设备、储能设备、配电网设备均满功率输出；当光伏发电功率减小3kW时，为了保证满足约束条件，用电设备自主调节用电功率同样减小3kW，满足能量平衡关系。而当用电设备功率减小3kW，破坏原有能量平衡时，光伏发电设备、储能设备、配电网设备按照1:1:1的配置关系(发电设备、储能设备、配电网设备各减小1kW)或特定的调节比例进行自主调节。极限调节方式为 单一能源调节，例如当用电设备功率减小3kW时，仅由配电网设备功率减小3kW来调节；用电设备功率一直减小直到电网出力不满足约束条件时，配电网设备不再接受能量调节。此时系统配置光伏发电设备功率为5kW，储能设备功率为5kW，用电负载功率为10kW，相当于发电设备、储能设备、用电设备按照1:1:2的离网极限架构；同样，在光伏或负载能量发生变化时，在上述能量平衡关系下，以配置比例或特定调节方式进行调节。
系统中发电设备、储能设备、用电设备、配电网设备某部件能量有发生变化时，其余各部件将按照预设的调节方式进行调节。若系统内多部件能量同时发生变化，则调节量按规则叠加即可。其中，系统离网运行时(u,i,p,q) grid＝0。
对于多维度能源互联网系统，如图4、5所示的三维度系统中，系统α、系统β、系统γ均单独正常运行，系统实时监测发现系统α能量突增10kW，经系统α内部调节至各部件均达到自身允许冗余能力上限，还有4kW无法消纳，此时将能量调度至系统β、系统γ进行消纳，系统β、系统γ则根据提前预设的调度方法进行能量分配，再自行调节。又如系统运行过程中系统β用电负载突然增大，经系统β内部调节至各部件均达到自身允许冗余能力上限，还无法满足用电需求，则调度系统α或(和)系统γ进行能量补充。
另外，能源互联网还可以通过管理系统设置一些特定运行模式或定制化的调度。如：系统β运行在峰值电价时，可要求光伏等发电设备盈余时不给储能设备充电，而进行并网，创造收益；在谷值电价时由电网设备给储能设备充电等等。

在该实施例中，各个维度电压参数、电流参数、功率参数和电量参数都应满足能量平衡约束条件，从而实现系统能量平衡，使得系统能够稳定运行。
