| 摘要: |
| 随着城市经济发展与终端用能电气化的普及，以制冷用电为首的电负荷需求持续增加且峰谷差情况愈发严重化，导致现有配电网运行负担逐渐加重。在此背景下，将综合能源站(IES)作为多能流耦合节点，在配电网中引入多能协调互补及蓄能移峰功能，计及多个阶段负荷发展及多类型负荷特征，提出在IES柔性调控作用下的配电网多阶段规划方法。基于IES能流结构及其运行机制，分别在不同气候类型地区负荷模拟场景下，以总规划期内投资与运行经济性最优为目标，建立由线路、变电站和IES构成决策对象的配电网双层多阶段规划模型，规划与运行层模型通过决策变量关联达成一体化协同求解。通过修改后的IEEE 33节点配电系统对所提方法的有效性进行校验，并进一步将所提方法应用于某地实际152节点配电系统，分析不同负荷特征下配电网规划运行效益、负荷峰谷差调节效果及IES运行状况，得出计及IES的城市配电网规划方法的实用性结论。 |

| Abstract: |
| With the development of urban economy and the popularization of electrified end-use energy, the demand for electric load, led by refrigeration electricity, continues to increase and the peak-to-valley difference becomes more and more serious, which causes gradual increasing operation burden of the existing distribution network. In this context, taking IES(Integrated Energy Station) as a multi-energy flow coupling node, the multi-energy coordination and complementary function and power storage peak load shifting function are introduced into distribution network. Taking multi-period load development and characteristics of multi-type loads into account, a multi-stage planning method for distribution network under the regulation of IES is proposed. Based on energy flow structure of IES and its operating mechanism, a two-layer multi-stage planning model of distribution network under multiple load simulation scenarios in different climatic regions is established, which takes optimal investment and operation economy during the total planning period as the objective, takes lines, substations and IES as decision objects. The planning and operation layer model achieves integrated collaborative solution through associated decision variables. The effectiveness and generality of the proposed method are verified by modified IEEE 33-bus distribution network system. Furthermore, the proposed method is applied to an actual 152-bus distribution system in a certain place, the benefit of distribution network planning operation, load peak-valley difference adjustment and IES operation under different load characteristics are analyzed, by which the practical conclusions of the urban distribution network planning method considering IES are obtained. |
