With increased integration of renewable resources into the power distribution system,
bidirectional ac/dc converters are gaining popularity in interfacing the utility grid and
energy storage systems. This thesis presents design and modeling of a three-phase
bidirectional PWM ac/dc converter with high power factor, low current THD, and high
efficien...

... In a single-stage PV system, because of inherent limitations of inverters [10], the dc-link voltage, V dc , should always be kept above a minimum voltage threshold, so operation on the right side of the MPP is necessary. ...
This paper presents an algorithm for power curtailment 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.
