摘要:
本文提出了一种利用多功能光伏–蓄电池发电系统参与电网二次辅助调频的新方案。该方案利用并网逆变器快速灵活的可控性,将光伏发电由间歇波动的不可调度电源转变为主动参与电网安全稳定运行的“好公民”,不仅有助于增强电网对分布式光伏的消纳能力,更能改善电网的电能质量。当电网频率异常时,综合考虑并网逆变器的额定容量、光照条件、蓄电池充放电状态等实际情况,分析光伏–蓄电池发电系统参与电网二次辅助调频的多种运行模式,提出了一种分层控制策略。

Abstract: A novel control strategy was proposed to participate in auxiliary second frequency regulation of the power grid by using the multi-functional Photovoltaic (PV)-battery system. The scheme can make the intermittent, fluctuating and non-dispatched PV to participate in grid security and sta-bility operation as “good citizens” actively based on the fast and flexible controllability of grid-connected inverter. That can enhance grid absorbability to PV power generation and the value of PV power generation. When the grid frequency is abnormal, multiple operation modes of the PV-battery generation systems participating in the auxiliary second frequency regulation were analyzed and a hierarchical control strategy was presented considering the rated capacity of grid-connected inverter, solar radiation conditions, battery charge and discharge status, etc.
