【摘要】：储能电站接入电网具有改善电网电能质量、提高电力系统可靠性、参与电网的“削峰填谷”等的重要功能。另一方面,既使用电能又充当电能存储装置的动力电池作为分布式储能装置直接接入配电网后会引入各种扰动,引起系统电压波动、频率偏差和谐波等电能质量问题。如何通过调整集中充电站电池储能系统的并网方式,尽可能得发挥储能电站的功能,提高其经济利用率的同时实现与系统的稳定并网,亟需深入探讨。本文主要通过现有的电力系统软件,以杭州市滨江集中充换电站为实例建立储能电站模型,结合理论与储能电站接入前后的仿真结果,从储能电站接入对配电网可靠性、电能质量、电压及调峰三方面的影响展开研究。在现有的电力系统软件下,德国亚琛大学的电力系统可靠性软件RAMSES适用于评估配电网的可靠性；PSCAD软件下能够用于衡量配电网的电能质量情况；DIgSILENT软件适合建立储能模型,以此分析储能电站对配网潮流和调压的作用。在对应软件下建立储能电站的模型,通过储能电站接入前后的仿真结果比较进行分析。
[Abstract]:The access of energy storage power station to the power network has the important functions of improving the power quality, improving the reliability of the power system and participating in the "cutting peak and filling the valley" of the power network. On the other hand, the power battery, which uses both electric energy and energy storage device as a distributed energy storage device, will introduce a variety of disturbances into the distribution network, which will lead to power quality problems such as voltage fluctuation, frequency deviation and harmonics. How to adjust the grid-connected mode of battery energy storage system in centralized charging station, how to exert the function of energy storage power station as much as possible, and how to improve its economic utilization ratio and realize the stable grid connection with the system, need to be deeply discussed. Based on the existing power system software, the model of the storage power station is established with the example of Hangzhou Binjiang centralized charging power station. Combining with the theory and the simulation results before and after the access of the energy storage power station, the reliability of the distribution network is obtained from the access of the energy storage power station. The effects of power quality, voltage and peak regulation are studied. Under the existing power system software, the power system reliability software RAMSES of the University of Aachen in Germany is suitable for evaluating the reliability of the distribution network. Under the software RAMSES, it can be used to measure the power quality of the distribution network. The effect of energy storage power station on power flow and voltage regulation of distribution network is analyzed. The model of the energy storage power station is established under the corresponding software, and the simulation results before and after the access of the energy storage power station are compared and analyzed.
