摘要(Abstract):
为保证微电网系统稳定运行、各发电单元之间功率平衡以及输出电能质量良好,采用混合储能装置作为含光伏发电微电网系统的储能部分。提出了含光伏发电单元的微电网系统并网运行时各储能单元和直流母线电压的控制策略。当光伏发电并网系统的能量管理采用功率分配型控制策略时,直流母线电压幅值的稳定受发电单元侧控制,通过控制微电源与三相逆变器输送给电网能量之间的平衡来保持直流母线电压稳定;当新能源或本地负载功率发生突变时,由于蓄电池和超级电容储能装置具有较好的能量互补特点,通过控制蓄电池吸收或释放低频功率,超级电容吸收或释放高频功率,可以抑制负载突变对直流母线造成的冲击。仿真和实验结果表明,上述控制策略能有效、快速地调节系统有功、无功功率输出,抑制微电网系统负荷突变引起的功率波动,改善系统输出电能质量,提高系统的可靠性和稳定性。
