AI总结:

该研究针对电池容量选型模型过度简化运行细节易引发非最优容量及长期财务损失的问题,对比了传统方法与纳入滚动时域运行的模型,经社区电池储能案例验证,现有方法最多可致22%的财务损失。

摘要:

最优电池容量选型研究往往在电池容量选型框架内过度简化电池运行的实际层面。此类假设可能导致电池容量非最优,进而给运营周期可超过十年的电池项目带来重大财务损失。本文将文献中最常见的现有选型方法,与纳入电池实际运行模式(即滚动时域运行)的电池容量选型模型进行对比。随后,我们针对社区电池储能(CBS)的真实案例研究,量化了这些模型得出的非最优容量所造成的财务损失。我们通过为CBS及本地终端用户构建数学框架来开展案例研究。结果表明,现有选型方法可能导致高达22%的财务损失。

英文摘要:

Optimal battery sizing studies tend to overly simplify the practical aspects of battery operation within the battery sizing framework. Such assumptions may lead to a suboptimal battery capacity, resulting in significant financial losses for a battery project that could last more than a decade. In this paper, we compare the most common existing sizing methods in the literature with a battery sizing model that incorporates the practical operation of a battery, that is, receding horizon operation. Consequently, we quantify the financial losses caused by the suboptimal capacities obtained by these models for a realistic case study related to community battery storage (CBS). We develop the case study by constructing a mathematical framework for the CBS and local end users. Our results show that existing sizing methods can lead to financial losses of up to 22%.
