论文摘要
本文提出了一个简单且灵活的存储模型，用于在各种多期最佳功率流问题中使用。该模型旨在在以下关键特征启用的各种环境中进行研究：（i）该模型可以代表各种尺度的能量缓冲区的动力学，从住宅电池存储到网格尺度泵送水力； （ii）它与功率流程方程的平衡和不平衡公式兼容； （iii）凸松弛和线性近似，以使所提出的模型无缝整合到需要开发凸度或线性的应用中； （iv）提出了一个简约和标准化的数据模型，以促进研究界易于使用。提出的模型使用概念验证二十四小时存储计划任务进行验证，该任务证明了模型的关键功能的值。作为PowerModels和PowerModelsDistribution优化工具箱的一部分，提供了模型的开源实现。
This paper proposes a simple and flexible storage model for use in a variety of multi-period optimal power flow problems. The proposed model is designed for research use in a broad assortment of contexts enabled by the following key features: (i) the model can represent the dynamics of an energy buffer at a wide range of scales, from residential battery storage to grid-scale pumped hydro; (ii) it is compatible with both balanced and unbalanced formulations of the power flow equations; (iii) convex relaxations and linear approximations to allow seamless integration of the proposed model into applications where convexity or linearity is required are developed; (iv) a minimalist and standardized data model is presented, to facilitate easy of use by the research community. The proposed model is validated using a proof-of-concept twenty-four hour storage scheduling task that demonstrates the value of the model's key features. An open-source implementation of the model is provided as part of the PowerModels and PowerModelsDistribution optimization toolboxes.
