“…For one SISO model, there is only one corresponding set of nonlinear estimators for input and output, and one set of linear parameters, i.e. pole b n, zero f n and delay n k , as written in the equation (9). For SIMO, MISO and MIMO models, there would be more than one set of nonlinear estimators and linear parameters.…”

“…Fluctuation of weather condition, variations of loads and grids, connecting PV-based inverters to the power system, requires power quality control to meet standards of electrical utilities. PV can reduce or improve power quality levels [6][7][8][9]. Different aspects should be taken into account.…”

-This paper proposes a point of common coupling (PCC) voltage compensation algorithm using a current limitation strategy for use in distributed generation (DG). The proposed strategy maintains the PCC voltage by prioritizing currents when an output current reference is larger than the current capacity of the power condition system (PCS) of the DG. With this strategy, the DG outputs the active current, reactive current, and the negative sequence current. The DG uses the reactive current for maintaining the PCC voltage within a normal range; the negative sequence current is used for reducing the PCC voltage unbalance. The proposed method was verified using PSIM simulation and experimental results.

“…In all the aforementioned applications, multilevel converters are being increasingly considered as a fundamental technology, as a result of their capability to handle high-power, utilizing low voltage power devices, whilst maintaining superior quality output waveforms, even at low device switching frequency [12]- [17]. Amongst all the possible multilevel converter topologies [2], [18], [19], Cascaded HBridge converters (CHB) represent an interesting solution in several applications where its reduced number of components when compared to other multilevel converter topologies and high modularity are important features which lend themselves to the improvement of overall system efficiency and reliability [20].…”

Abstract-In this paper a dedicated PWM technique specifically designed for single-phase (or four wire three-phase) multilevel Cascaded H-Bridge Converters is presented. The aim of the proposed technique is to minimize the DC-Link voltage unbalance, independently from the amplitude of the DC-Link voltage reference, and compensate the switching device voltage drops and on-state resistances. Such compensation can be used to achieve an increase in the waveform quality of the converter. This is particularly useful in high-power, low supply voltage applications where a low switching frequency is used. The DCLink voltage balancing capability of the method removes the requirement for additional control loops to actively balance the DC-Link voltage on each H-Bridge, simplifying the control structure. The proposed modulation technique has been validated through the use of simulation and extensive experimental testing to confirm its effectiveness.
