Gaoya dianqi, 2018 随着直流微电网系统的广泛应用,其控制技术得到不断关注。直流微电网系统由光伏阵列、电动汽车充换站、大电网及其接口变换器构成。针对其结构特点,采用一种能量协调控制策略以维持直流母线的电压稳定。该控制策略根据直流微电网中母线电压信息（DBS）进行运行模式划分,不同运行模式下,直流微电网各单元的控制策略可进行无缝切换,实现系统协调自治。采用下垂控制实现对多个光伏阵列或者电动汽车蓄电池模块的功率均分。仿真结果表明,直流母线电压保持稳定的同时,直流微电网系统能够在并离网不同模式间进行平滑切换 ...

Dianci bileiqi光储微电网是解决偏远地区供电问题的重要手段，有必要做好雷电感应过电压防护以确保系统长期稳定运行。利用PSCAD软件搭建独立光储微电网仿真电路模型，计算微电网内埋地电缆雷电感应过电压，分析感应过电压在系统直流侧和交流侧的传递特性，讨论电缆埋深和电缆长度对过电压幅值的影响，最后分析安装SPD防护效果。研究结果表明：当独立光储微电网直流侧发生雷击时，埋地电缆感应产生较高幅值的过电压，过电压沿线缆传递至光伏阵列和储能系统，交流侧设备不受影响，同样，当交流侧发生雷击时，电缆感应过电压传递至逆变器交流侧和箱变前端 ...
