“…Basically, the amplitude of the dc-link voltage is dynamically modified, while the PV-string is not generating its maximum energy. In [48], a topology was introduced, denominated as an active NPC inverter. Such topology allows the interface of an ESS to be directly connected to the dc-link voltage, also eliminating the MPPT converter.…”

Nowadays, new challenges arise relating to the compensation of power quality problems, where the introduction of innovative solutions based on power electronics is of paramount importance. The evolution from conventional electrical power grids to smart grids requires the use of a large number of power electronics converters, indispensable for the integration of key technologies, such as renewable energies, electric mobility and energy storage systems, which adds importance to power quality issues. Addressing these topics, this paper presents an extensive review on power electronics technologies applied to power quality improvement, highlighting, and explaining the main phenomena associated with the occurrence of power quality problems in smart grids, their cause and effects for different activity sectors, and the main power electronics topologies for each technological solution. More specifically, the paper presents a review and classification of the main power quality problems and the respective context with the standards, a review of power quality problems related to the power production from renewables, the contextualization with solid-state transformers, electric mobility and electrical railway systems, a review of power electronics solutions to compensate the main power quality problems, as well as power electronics solutions to guarantee high levels of power quality. Relevant experimental results and exemplificative developed power electronics prototypes are also presented throughout the paper.

“…The control of the energy flow of DER can be performed by various isolated converters dedicated to each energy device or through a multiport converter. For technical and economic reasons multiport converters have some advantages over isolated ones, they present less complexity when controlling the entire system and they do not require communication between devices, making possible the centralization of energy management while reducing the number of system's controllers [4][5][6].…”

FBM-CSoC Control and Management System for Multi-Port Converter Applied in Hybrid Energy Storage System Used in Microgrid

et al. 2022

Several management and control techniques for hybrid energy storage systems (HESS) with batteries and supercapacitors are presented in the literature applied to microgrids (MGs). The filter-based control strategy for defining the control loop actuation is one of the most widely used approaches with satisfactory performance. Variations of the Filter-Based Method (FBM) method are proposed to improve the control efficiency of the HESS under load disturbance and intermittent generator sources. However, not enough attention has been paid to the impacts of MG on the operational performance of batteries, despite the fact that they represent a non-negligible percentage of the total cost of MGs. In this paper, a control strategy called FBM-CSoC is proposed that focuses primarily on mitigating battery safety and degradation issues. The control strategy proposes a distribution of the charging and discharging current in a weighted proportional way to the normalized rated capacity and current state of charge (SoC) of each battery in the MG. This control strategy favors both the reduction of the internal temperature variation of the cells and the possibility of them operating in overcharging or over-discharging conditions. A comparative case study between the traditional FBM method and the FBM-CSoC, by means of numerical simulations, demonstrated that the load distribution occurs satisfactorily in energy storage systems. Finally, the FBM-CSoC method can be flexibly used for different types of battery technology and/or batteries with different SoCs integrated with supercapacitors.

“…Finally, when a comparison with MMC-based systems [13] is considered, ANPC converters seem more appropriate, as MMC introduces a bulkier structure, and adds further complexity to the system [8]. Furthermore, ANPC systems were positively verified in terms of both three-wire [14] and EV charging systems [15].…”

All-SiC ANPC Submodule for an Advanced 1.5 kV EV Charging System under Various Modulation Methods

This work is focused on the design and experimental validation of the all-SiC active neutral-point clamped (ANPC) submodule for an advanced electric vehicle (EV) charging station. The topology of the station is based on a three-wire bipolar DC bus (±750 V) connecting an ac grid converter, isolated DC-DC converters, and a non-isolated DC-DC converter with a battery energy storage. Thus, in all types of power converters, the same three-level submodule may be applied. In this paper, a submodule rated at 1/3 of the nominal power of the grid converter (20 kVA) is discussed. In particular, four different modulation strategies for the 1.5 kV ANPC submodule, exclusively employing fast silicon carbide (SiC) MOSFETs, are considered, and their impact on the submodule performance is analyzed. Moreover, the simulation study is included. Finally, the laboratory prototype is described and experimentally verified at a switching frequency of 64 kHz. It is shown that the system can operate with all of the modulations, while techniques PWM2 and PWM3 emerge as the most efficient, and alternating between them, depending on the load, should be considered to maximize the efficiency. Furthermore, the results showcase that the impact of the different PWM techniques on switching oscillations, including overvoltages, can be nearly fully omitted for a parasitic inductance optimized circuit, and the choice of modulation should be based on power loss and/or other factors.
