摘要(Abstract)：

在城市电网中配置用户侧储能是解决可再生能源消纳能力不足、局部过载等运行问题的有效途径之一。因此，提出了一种考虑多运行场景的城市电网储能需求评估方法。通过出现频率与危害性来量化城市电网不同场景间的权重构成，选取正常运行、可再生能源消纳不足、局部过载场景构建城市电网用户侧储能需求评估模型。使用浙江省某区域城市电网37节点模型进行算例分析，结果表明该方法能够有效地评估城市电网用户侧储能需求，提高用户侧储能在不同运行场景下的复用率，与单运行场景储能需求评估方法相比，能够显著减少城市电网的用户侧储能总需求，并节约其投资与运行成本。
Deploying user-side energy storage in urban power grids is an effective solution to operational challenges such as insufficient capacity for renewable energy consumption and local overloads. Therefore, an assessment method for energy storage demand on the user side in urban power grids that considers multiple operational scenarios is proposed. The approach involves quantifying the weights between different scenarios in the urban power grid based on their frequency of occurrence and severity. Scenarios including normal operation, insufficient renewable energy consumption, and local overloads are chosen to construct a model to assess energy storage demand on the user side in urban power grids. Case studies are conducted using a 37-node model of an urban power grid in a region of Zhejiang Province. The results indicate that the method is effective in evaluating energy storage demand on the user side in urban power grids and improving the reuse rate of energy storage on the user side across various operational scenarios. Compared to methods for assessing energy storage demand in a single operational scenario, this approach significantly reduces the overall demand for energy storage on the user side in urban power grids and decreases both investment costs and operational costs.
