“…When the coupling system shown in Figure 1 connects a single-phase AC grid to a DC source, the problem of power ripple occurs. For this project, the ripple problem for on-board grids was solved and is described in detail in [25]. To design the power electronics coupling system an indirect photovoltaic converter, which consists of a boost converter, a DC-link circuit and a single-phase grid-tied inverter, was used.…”

This paper proposes a method for synchronizing a grid inverter with the voltage of an on-board high-frequency power grid. The described synchronization method belongs to the adaptive methods, which use fuzzy logic in the process of estimating the fundamental component of the voltage. The synchronization system has been tuned to achieve the primary goal of achieving synchronization in the shortest possible time. This is to allow for the efficient energy fed from photovoltaic sources into the on-board grid at 400 Hz. The proposed method was implemented in the field programmable gate array (FPGA) based power converter controller and static and dynamic tests for harmonic, interharmonic and subharmonic voltage disturbances were performed. Dynamic tests for phase jump, frequency jump and sag of the on-board voltage were also performed. To evaluate the effectiveness of synchronization with high-frequency voltage, the grid current control system in the grid tied inverter was elaborated. Proper current waveforms at the perturbed voltage were recorded while identifying the effectiveness of power ripple suppression. The results obtained were compared with the enhanced phase locked loop (EPLL) synchronization method. Satisfactory test results confirmed the suitability of the proposed method in systems coupling the photovoltaic source to the on-board high-frequency power grid.

“…The first feedback comes from the DC-link circuit voltage and is designed to control its value. To perform this task, a continuous low-bandwidth energy-storage capacitor voltage PI controller was implemented (according to [25]). The second feedback loop is to control the current feeding the on-board grid.…”

“…The elements of x * are selected to achieve the control objectives and fixed by a secondary level controller. The reference of the DC-link voltage is selected as v * dc = V * dc (constant), i * Bat comes from (29), and i * PV is obtained from a maximum power point tracker (MPPT) algorithm such as an incremental conductance (IC) algorithm [9,34].…”

Voltage Regulation of an Isolated DC Microgrid with a Constant Power Load: A Passivity-based Control Design

et al. 2021

View full text Add to dashboard Cite

Passivity-based nonlinear control for an isolated microgrid system is proposed in this paper. The microgrid consists of a photovoltaic array and a battery energy storage connected to a point of common converters, supplying a constant power load. The purpose of this control strategy is to maintain the output direct current voltage in its reference value under load variations, improving battery interaction. The system is represented by its state space averaged model and the proposed controller is designed using the interconnection and damping assignment strategy, which allows obtaining controller parameters while ensuring the closed-loop system stability. The unknown constant power load is estimated using an observer based on the energy function of the system. The behavior of the proposed control strategy is validated with simulation and experimental results.

“…The use of a grid converter connecting a dc bus to a single-phase ac grid causes a number of problems, the main one being the occurrence of power ripples with double grid frequency. The problem of their elimination has been studied in many research centers and presented in many articles [4,5,6,7,8].…”

This article presents a proposed system that enables energy transfer from the dc grid to a single-phase onboard grid, operating at an hi frequency. In addition to the energy transfer function, it additionally enables compensation of reactive power in the ac grid when the converter operates at less than rated power. To operate in compensator mode, it is necessary to decouple the current from the grid into active and reactive components and control them independently. To achieve good dynamics, synchronizers that operate in the dq system are used. In the case of a single-phase grid, it requires such a synchronizer to generate virtual quadrature signals. The used systems based on second-order generalized integrator are good, but to improve dynamics in the work a quadrature generator based on trigonometric calculations was proposed. The developed system was implemented in a proportional resonant current control system. Tests performed in steady state and in dynamic states related to typical grid disturbances showed better dynamic properties than the standard integrator-based system.Keywords: power transfer; compensator; P+R controller
