Abstract

Wind Energy Conversion systems (WECS), supplying islanded microgrids, often incorporate a Battery Energy Storage System (BESS) as an energy-buffer. To ensure safety and long life, the battery-bank (BB) in such systems must not be overcharged or deep-discharged. This paper proposes a reconfigurable operational strategy for a doubly-fed induction generator (DFIG) based islanded WECS integrated with a BESS. When the State-of-Charge (SoC) of the BB approaches the maximum limit, the rotor side converter regulates the DC bus voltage using a modified voltage controller while operating the DFIG away from the Maximum Power Point. When the BB-SoC approaches the minimum limit, a minimum consumer-discomfort factor based load-shedding strategy is proposed so that the BESS can regulate the DC-bus voltage without deep discharging the BB. The DFIG-BESS system supplying the benchmark CIGRE residential distribution network has been simulated in an Opal-RT real-time simulation environment. The proposed voltage controller shows 69.44% and 46.66% lower undershoot in the DFIG-stator active-power and 3.45% and 99.83% lower DC-voltage deviation compared to a PI-controller and latest literature, respectively, while transiting from the BESS to RSC based DC-bus voltage regulation. The proposed load-shedding strategy also reduces the DC-bus voltage dip significantly compared to a similar strategy proposed in the literature.

BESS辅助离网风能转换系统在不利的电池soc条件下运行

为孤岛微电网供电的风能转换系统（WECS）通常包含电池储能系统（BESS）作为能量缓冲。为确保安全性和长寿命，此类系统中的电池组（BB）不得过度充电或深度放电。提出了一种双馈感应发电机（DFIG）与BESS集成的孤岛WECS的可重构运行策略。当BB的充电状态（SoC）接近最大限制时，转子侧转换器使用修改的电压控制器调节直流母线电压，同时操作远离最大功率点的DFIG。当BB- soc接近最小极限时，提出了一种基于最小消费者不适因素的减载策略，使BESS能够在不深度放电BB的情况下调节直流母线电压。在Opal-RT实时仿真环境中，对提供CIGRE住宅配电网基准的DFIG-BESS系统进行了仿真。与pi控制器和最新文献相比，该电压控制器在从BESS过渡到基于RSC的直流母线电压调节时，dfig1 -定子有功功率的欠冲降低了69.44%和46.66%，直流电压偏差降低了3.45%和99.83%。与文献中提出的类似策略相比，所提出的减载策略还显著降低了直流母线电压降。
