Abstract

Nowadays, microgrids (MGs) are receiving a lot of attention. In an economical MG, the battery energy storage system (BESS) plays an important role. One of the biggest challenges in MGs is the optimal choice of the BESS that can lead to better performance of the MG, which will be more flexible, efficient, and effective than traditional power systems. In this paper, we present the modeling and simulation of different energy storage systems including Li-ion, lead-acid, nickel cadmium (Ni-Cd), nickel-metal hybrid (Ni-Mh), and supercapacitor (SC), for renewable energy applications, and more specifically for MGs. The results of simulation show that Li-ion batteries have a better response time than lead-acid batteries, Ni-Cd batteries, and Ni-Mh batteries and thus are more suitable for combination with supercapacitors. Li-ion batteries are the best option for fast-charging applications in MGs. The discharge phase ends with SOC ≤ ±94%, SOC ≤ ±95%, SOC = 95%, SOC < 95%, and SOC < 60%, respectively, for Li-ion, lead-acid, Ni-Cd, Ni-Mh, and supercapacitor. Moreover, the use of the battery management system (BMS) can significantly improve the performance of BESS, leading to higher levels of SOC and longer life span. The obtained results have shown that with an optimization algorithm for energy storage systems, more specifically for the battery-charging mode, the response time of BESSs can be further improved. The effect of ambient temperature has also been investigated on the functional capacities of the batteries. The obtained results demonstrated that extreme temperatures (80°C to −80°C) have a significant impact on battery performance and capacity, especially for Li-ion batteries, with a drop in capacity of up to 50% at −40°C. This highlights the importance of considering the ambient temperature in the design and operation of MGs. Overall, our study provides valuable insights into the optimal selection of BESS and the impact of ambient temperature on their performance, which can help in the development of more efficient and reliable MGs.

微电网储能技术比较分析

如今，微电网（MGs）正受到广泛关注。在经济型微电网中，电池储能系统（BESS）发挥着重要作用。微电网面临的最大挑战之一是如何优化 BESS 的选择，从而提高微电网的性能，使其比传统电力系统更加灵活、高效和有效。在本文中，我们介绍了不同储能系统的建模和仿真，包括锂离子、铅酸、镍镉（Ni-Cd）、镍金属混合（Ni-Mh）和超级电容器（SC）。模拟结果表明，锂离子电池的响应时间优于铅酸电池、镍镉电池和镍氢电池，因此更适合与超级电容器结合使用。锂离子电池是导航仪快速充电应用的最佳选择。锂离子电池、铅酸电池、镍镉电池、镍氢电池和超级电容器的放电阶段分别以 SOC ≤ ±94%、SOC ≤ ±95%、SOC = 95%、SOC < 95% 和 SOC < 60% 结束。此外，使用电池管理系统（BMS）可以显著提高 BESS 的性能，从而提高 SOC 水平并延长使用寿命。研究结果表明，利用储能系统优化算法，特别是针对电池充电模式的优化算法，可以进一步改善 BESS 的响应时间。此外，还研究了环境温度对电池功能容量的影响。研究结果表明，极端温度（80°C 至 -80°C）对电池性能和容量有显著影响，尤其是对锂离子电池，在 -40°C 时容量下降高达 50%。这凸显了在设计和运行微型发电机时考虑环境温度的重要性。总之，我们的研究为最佳选择 BESS 以及环境温度对其性能的影响提供了宝贵的见解，有助于开发更高效、更可靠的 MG。
