| 中文摘要: |
| 配电网中分布式光伏具有分布广、间歇性强的特点，其就地消纳的特性造成配电网减碳贡献分配不均。为公平衡量分布式光伏与储能装置在配电网中的减碳作用，首先通过双向网损分摊，将实际有损网络转化为无损虚拟网络，进而得到一个时间断面下的碳排放流分布。然后，计算长时间尺度下分布式光伏的计划功率与实际功率对应的碳流分布，从而得到分布式光伏的相对碳排放强度。最后，计算不同配电网储能容量场景下分布式光伏的相对碳排放强度，并以此为依据衡量储能装置的减碳作用，从而提出一种满足公平分配原则的含光伏储能的配电网减碳贡献分配方法，并在标准算例中进行验证。 |

| Distributed photovoltaic device in distribution network has the feature of wide distribution and strong intermittency. Its local consumption characteristic causes unbalanced distribution of carbon reduction contributions in distribution network. In order to measure the carbon reduction effect of distributed photovoltaic and energy storage devices in distribution network fairly,real lossy network is transformed into lossless virtual network through two-direction network loss allocation,and then the carbon emission flow distribution under a time section is obtained. Then,the carbon flow distribution corresponding to the planned power and actual power of distributed PV in longtime scale is calculated respectively to obtain the relative carbon emission intensity of distributed PV. Finally,the relative carbon emission intensity of distributed photovoltaic under different distribution network energy storage capacity scenarios is calculated,which is the basis of carbon reduction effect measurement of energy storage devices,so as to propose a carbon reduction contribution distribution method in distribution network including photovoltaic and energy storage devices that meets the principle of fair distribution,and the standard calculation example is verified. |
