【摘要】：微电网既可以并网运行,也可以孤岛运行,而孤岛模式下主控微源对电压和频率调节作用的强弱对微电网能否稳定运行影响显著。基于已搭建的以储能电池为主控微源的光储柴微电网,分别在蓄电池不同荷电状态、负载不同程度扰动、是否投入柴发微源的情况下进行三组对比实验,用三相电能质量分析仪记录相关波形,分析不同实验条件下微电网的运行特性。实验结果表明,蓄电池的荷电状态、负载的扰动情况对微电网的稳态孤岛运行有重要影响;柴发微源的投入会抢占蓄电池对电压和频率调节的主导作用,需对蓄电池容量进行优化配置。根据实验结果,对蓄电池容量进行了优化,可以保证蓄电池的主导作用。
[Abstract]:The microgrid can be operated both grid-connected and islanding. The effect of the main control microsource on voltage and frequency regulation is significant in isolated island mode. Based on the built optical storage microgrid with energy storage battery as the main control micro-source, the microgrid has a significant effect on the stability of the micro-grid. Three groups of comparative experiments were carried out under the condition of different charging state of battery, different disturbance of load, whether or not to put into firewood microsource, and the relevant waveforms were recorded by three-phase power quality analyzer. The operating characteristics of microgrid under different experimental conditions are analyzed. The experimental results show that the charging state and load disturbance of the battery have an important effect on the steady island operation of the microgrid. The input of Chai Fa micro source will preoccupy the leading role of battery in voltage and frequency regulation, so the battery capacity needs to be optimized. According to the experimental results, the battery capacity is optimized. Can guarantee the leading role of the battery.
