摘要:
针对分布式发电及大量接入电动汽车对有源配电网功率和电压质量影响日益严峻的问题,首 先从储能容量及功率、日负荷曲线特性和单位时间角度分析了影响区间控制的因素,提出了一种改进区 间控制的储能出力模型来解决蓄电池储能电站一个周期内多次充放电问题进一步,基于随机变量相关 性的点估计概率潮流算法以分析分布式发电、电动汽车及储能电站接入配电网对电压水平的影响;最 后,针对含蓄电池储能电站的改进IEEE-33节点有源配电网系统进行仿真分析,实验结果验证了接入储 能电站可以有效地降低系统功率及电压波动.
Abstract:
With the massive integration of distributed generation and electric vehicles, the problems of power and voltage quality in active distribution network were increasingly shown. Aiming at this issue, the factors affecting the interval control were analyzed in terms of energy storage capacity and power, daily load curve characteristics and unit time firstly. An improved interval control method for energy storage output model was then proposed to solve the problem of multiple charging/discharging operation in one cycle. Considering the correlation of random variables, probabilistic load flow using point estimate method was analyzed to state the influence of distributed generation, electric vehicles and energy storage station on voltage level. Finally, simulation analysis was operated on the improved IEEE-33 node active distribution network system with battery energy storage station. The results showed that the integration of energy storage station could effectively reduce the fluctuation of system power and voltage.
