论文摘要
本文提出了一种在快速太阳辐照度间歇性下的光伏（PV）系统功率降低算法。基于扰动和观察（P＆O）技术，该方法包含一种自适应增益，可实时补偿以说明较低功率可用性的时刻。另外，将累加器添加到台阶的计算中，以减少由大型辐照度波动引起的过冲。 OPAL-RT EMEGASIM实时模拟器上开发了三相单阶段的500 kVA PV系统的测试台。使用PJM（RTO）的现场辐照度数据和调节信号来比较所提出的方法的性能与文献中发现的其他技术。结果表明操作较小，较小的直流链接电压振荡和提高功率参考跟踪能力的操作。
This paper presents an algorithm for power curtail-ment of photovoltaic (PV) systems under fast solar irradiance intermittency. Based on the Perturb and Observe (P&O) technique, the method contains an adaptive gain that is compensated in real-time to account for moments of lower power availability. In addition, an accumulator is added to the calculation of the step size to reduce the overshoot caused by large irradiance swings. A testbed of a three-phase single-stage, 500 kVA PV system is developed on the OPAL-RT eMEGAsim real-time simulator. Field irradiance data and a regulation signal from PJM (RTO) are used to compare the performance of the proposed method with other techniques found in the literature. Results indicate an operation with smaller overshoot, less dc-link voltage oscillations, and improved power reference tracking capability.
