“…The second one obtains the current components in the DQ synchronous reference frame, and the third one considers following a sinusoidal current with unitary power factor. The results emphasize that the performance is alike for ideal conditions; however, it is determined that, for voltage unbalances or voltage distortion, the synchronous reference frame largesse has the best performance, due to the fact that the system is unaffected by voltage disturbances [3].…”

“…In recent years, the use of power converters to control active and reactive power in AC-AC grid-connected systems has increased. Basically, the power converter is used to control the power flow between two AC sources with the same or different electrical characteristics [1][2][3][4]. However, the selection of the topology depends on the power application and the type of interfacing bus.…”

Nowadays, the use of power converters to control active and reactive power in AC–AC grid-connected systems has increased. With respect to indirect AC–AC converters, the tendency is to enable the back-to-back (BTB) voltage source converter (VSC) as an active power filter (APF) to compensate current harmonics. Most of the reported works use the BTB-VSC as an auxiliary topology that, combined with other topologies, is capable of active power regulation, reactive power compensation and current harmonic filtering. With the analysis presented in this work, the framework of the dynamics associated with the control loops is established and it is demonstrated that BTB-VSC can perform the three tasks for which, in the reviewed literature, at least two different topologies are reported. The proposed analysis works to support the performance criteria of the BTB-VSC when it executes the three control actions simultaneously and the total current harmonic distortion is reduced from 27.21% to 6.16% with the selected control strategy.

The development of microgrids is of great interest to facilitate the integration of distributed generation in electricity networks, improving the sustainability of energy production. Microgrids in DC (DC-MG) provide advantages for the use of some types of renewable generation and energy storage systems, such as batteries. In this article, a possible practical implementation of an isolated DC-MG for residential use with a cooperative operation of the different nodes is proposed. The main criterion is to achieve a very simple design with only primary control in a residential area. This application achieves a simple system, with low implementation costs, in which each user has autonomy but benefits from the support of the other users connected to the microgrid, which improves its reliability. The description of the elements necessary to create this cooperative system is one of the contributions of the work. Another important contribution is the analysis of the operation of the microgrid as a whole, where each node can be, arbitrarily, a consumer or an energy generator. The proposed structures could promote the use of small distributed generation and energy storage systems as the basis for a new paradigm of a more sustainable electricity grid of the future.

Boost converters have been widely employed in industrial applications, and cascading boost converters is a mature technique to realize ultrahigh voltage gains.However, the cascade structure inevitably increases the voltage stress of buffer capacitors, resulting in high costs and low energy efficiency. Targeting this issue, in this study, we propose a novel extendable single-switch n-cell boost converter (ESSnB), which utilizes the same number of components as the conventional positive output boost converter, but has lower buffer voltage stresses. Simulation and experimentation are conducted in this study, which verify the effectiveness and superiority of the proposed ESSnB over conventional boost converters. KEYWORDS extendable multicell converter, low component stress, single-switch boost converter INTRODUCTIONHigh step-up converters have been playing an indispensable role in modern renewable energy-integrated power grid, but traditional boost converters, with a simple circuit structure and control schemes, cannot realize the high voltage gains that are required in modern renewable energy sector. [1][2][3][4][5][6] In order to achieve a high voltage gain, various high step-up converters on a single-stage basis have been proposed and applied in wide-ranging applications to realize desired voltage gains, such as clamped-inductor, 7,8 switched-capacitor, 9,10 impedance network, 11-13 switched-inductor, [14][15][16] voltage multiplier, 17,18 and magnetic coupling. 19,20 However, single-stage converters can no longer satisfy high-voltage gain requirements in current power system applications, and a common method to overcome this limitation is to implement various voltage-pumping techniques into a number of identical or different converter modules. [21][22][23] As shown in Figure 1, cascading boost converter is the simplest method to obtain a high-voltage conversion ratio. However, a larger number of converters connected in series leads to lower energy efficiency and causes difficulties in control design. 24 To solve these problems, a group of positive Int J Circ Theor Appl. 2020;48:817-831.wileyonlinelibrary.com/journal/cta
