摘　　要：为应对日趋严峻的气候问题,中国提出了“双碳”战略目标,能源低碳转型已成为共识。配电系统在可再生能源消纳和用户侧减排方面发挥着重要作用,同时面临新的挑战。城市作为能源消耗的中心,具有显著的聚集碳排效应,城市配电网的低碳转型需求迫切。本文首先提出了计及源网荷储协同运行的城市配网侧储能系统框架。其次,考虑储能系统各项成本,构建储能容量配置模型。进而,计及系统中储能运行、配电网潮流约束等条件,目标为系统运行成本最低,构建系统优化调度模型。最后,计及储能容量配置与源网荷储协同调度运行,构建规划-运行双层优化模型,并通过算例验证本文所提优化配置方案的有效性。In order to cope with the increasingly severe climate change problem,China has put forward the“double carbon”target,and energy low-carbon transformation has become a global consensus.While the distribution system plays an important role in promoting accommodation of renewable energy and reduction of users'carbon emission,it will also face new challenges.As the center of energy consumption,cities have significant carbon emission effect,so the low-carbon transformation of urban distribution network is in urgent need.Firstly,the framework of urban distribution network side energy storage system considering the cooperative operation of source network load storage is proposed.Secondly,the capacity optimization configuration model of energy storage system is established,considering the cost of energy storage system in the whole life cycle.Thirdly,a system optimization scheduling model is established considering the constraints such as energy storage and power flow in the distribution network,and aiming at the lowest comprehensive operation cost of the system.Finally,a dual-layer optimization model of planning-operation is constructed,considering the capacity optimization of the energy storage system and the optimal scheduling of the load-storage cooperative operation system of the source network,and the effectiveness of the proposed optimal configuration scheme is verified by a numerical example.
