论文摘要
最佳BESS分配问题中电池储能系统（BESS）最常用的模型是恒定效率模型。但是，贝斯的充电和放电效率随着其最新电荷，温度，充电/放电能力以及所考虑的贝斯技术的功能而异。因此，恒定效率模型可能不准确地代表BES的非线性工作特性。在本文中，我们首先创建了从实际非线性BESS模型中得出的技术特异性线性化BESS模型。然后，我们将线性化的BESS模型纳入混合构成线性编程框架中，以进行最佳的多技术BES分配。对2,604个公共汽车的传输网络进行的研究表明，从模型的准确性，凸性和计算性能的角度使用线性化的BES模型的好处。
The most commonly used model for battery energy storage systems (BESSs) in optimal BESS allocation problems is a constant-efficiency model. However, the charging and discharging efficiencies of BESSs vary non-linearly as functions of their state-of-charge, temperature, charging/discharging powers, as well as the BESS technology being considered. Therefore, constant-efficiency models may inaccurately represent the non-linear operating characteristics of the BESS. In this paper, we first create technology-specific linearized BESS models derived from the actual non-linear BESS models. We then incorporate the linearized BESS models into a mixed-integer linear programming framework for optimal multi-technology BESS allocation. Studies carried out on a 2,604-bus U.S. transmission network demonstrate the benefits of utilizing the linearized BESS models from the model accuracy, convexity, and computational performance viewpoints.
