Finite-set model predictive control (FS-MPC) algorithms provide excellent dynamic performance for the power electronics converters with the ability to easily include any non-linearities and constraints. However, the high number of iterations required for prediction and cost function evaluation, especially for multi-level converters, hampers the implementation of the FS-MPC techniques. In this paper, firstly, the deadbeat concept is utilized to directly obtain the reference voltage vector. Accordingly, the iterations required for prediction are eliminated. Secondly, the number of iterations for cost function evaluation is also reduced by selecting a certain number of voltage vectors based on the value of the reference voltage vector. Finally, experimental results using hardware in the loop (HIL) technology are given to validate the proposed FS-MPC technique. © 2023 IEEE.

This study focuses on the design and simulation of a robust 500 kW charger for electric vehicle (EV) charging applications using MATLAB SIMULINK software. The charger consists of two channels, each comprising five dual active bridge (DAB) converters arranged in a series configuration at the input side and interconnected in parallel at the output terminals. Each DAB converter can transfer up to 50 kW of power, resulting in a total power transfer capacity of 250 kW per channel. Precise control is achieved through a phase shift control strategy employed by each DAB converter. The system's performance was thoroughly tested within a dynamic power range of -50 kW to 50 kW for each DAB converter, showcasing excellent controller response. The results demonstrate the effectiveness and suitability of the DAB converter for EV charging stations. © 2023 IEEE.

This paper proposes a new method for improving the performance of grid-connected single-stage Quadratic Boost Inverters (QBIs). Compared to the other single-stage boosting inverters, such as ZSI, qZSI, and the basic SSI, QBI has several advantages. It combines the features of a quadratic dc-dc boost converter and Split-Source Inverter (SSI) to give a high voltage gain. As a result, it offers superior benefits in reducing the overall system's complexity, size, and cost. The grid-connected QBI is traditionally controlled via two control loops. The first loop regulates the dc-link voltage using a PI controller, while the second controls the current injected into a grid using the decoupled control approach. In this paper, a sliding mode controller (SMC) is proposed for the grid-side controller to achieve accurate and quick responses instead of using the decoupled approach that is based on PI controllers. The basic principles and detailed analysis of the proposed method are introduced. Moreover, comprehensive simulation results based on the actual parameters of a prototype have verified the overall control system and the advantages of the proposed SMC compared to the PI controller. © 2022 IEEE.

Additive manufacturing has enabled the use of advanced geometries such as lattice-structures in heatsinks. This study investigates the thermal performance of various advanced heatsink designs in the context of cooling the windings of an axial flux motor using active air cooling. Physical samples of the heatsinks are additively manufactured from an aluminum alloy and tested under realistic airflow conditions. The heatsink designs are compared against an optimized conventional finned geometry based on the measured thermal resistance at a given fan speed. This ensures that the results are representative of real-world use cases and applicable in practical solutions. The results indicate that airfoil-shaped pins can slightly outperform conventional straight fins in thermal resistance while weighing less. In terms of mass-based relative performance, the rhombi octet lattice structure outperformed the other prototypes. These findings reinforce conventional design principles in terms of absolute performance while suggesting that lattice structures can provide higher relative performance in certain weight sensitive applications. © 2013 IEEE.

Based on security constrained convex optimal power flow (SC-COPF), this paper proposes an energy and operational reserve scheduling approach for the power system. The proposed approach is capable of scheduling energy and operational reserve dynamically according to the power load forecast and the power generation from renewable energy. Reserve requirements to keep the power system in the acceptable security level is equivalently formulated as the linear constraints in the SC-COPF model. The reserve requirements are considered in a statistical way which is a common practice in the power system operations in Europe. For example, the practice in Switzerland of reserve scheduling is to ensure that the maximum probability of power insufficiency should be less than 0.2%. The objective is to minimize the economic cost of the energy production and the reserve provision. The convex optimal power flow (COPF) is used to model the AC power flows of the power network. The capacity constraints of transmission lines are considered in our SC-COPF model by equivalently constraining the power loss variables. The proposed approach is validated by using the modified European transmission network 1354pegase test case. The power load forecast and power generation from renewable energy data from Réseau de Transport d'EÉlectricite (RTE) in France are used for the validation. Numerical results show efficiency of our approach to dynamically schedule the energy and reserve. © 2021 IEEE.

IEEE PES Conference on Innovative Smart Grid Technologies - Middle East (ISGT Middle East)

作者： Vedran Bobanac Hrvoje Pandžić Department of Energy and Power Systems University of Zagreb Faculty of Electrical Engineering and Computing Croatia

Wide adoption of lithium-ion batteries brings up the question of their fast charging ability which is still an issue in many applications. This is probably the most important for electric vehicles, but also for battery energy storage and even consumer electronics. Charging times can be reduced by using new battery materials, but also by using alternative charging strategies. This paper presents a novel method for quantifying battery’s ability to accept charge in some arbitrary time interval. The proposed method can be used to quickly and effectively compare different battery technologies, different charging strategies or any possible charging condition that might be adjusted, while taking into account battery’s charging ability throughout the entire state-of-charge range. This is achieved by introducing novel fast charging comparison metrics. The method is demonstrated by analyzing and comparing the fast charging ability of four lithium-ion battery cells of different chemistries. Input data are obtained experimentally, on a proprietary laboratory testbed.

As global energy demand continues to rise, concerns about climate change, environmental issues, and the depletion of fossil fuel resources require a careful consideration of the use of renewable energy, including solar energy. Vietnam's solar power plant (SPP) capacity has expanded considerably in recent years. However, technical and economic calculations for large-scale solar power plants and comparisons with other power plants are still limited. In this paper, the technical and economic aspects of solar power plants will be evaluated, with key economic indicators such as net present value (NPV), levelized cost of energy (LCOE), internal rate of return (IRR), benefit-cost ratio (BCR), and payback period (PB) being analyzed for both current and future scenarios. The results show that all power plants are economically effective. Furthermore, with investment costs for solar power plants decreasing rapidly, solar power plants will have high economic efficiency in the future. The useful information for investing and developing renewable energy policies in Vietnam is also presented in this paper. © 2025 IEEE.

This paper presents the speed control of a six-phase induction machine (SPIM) fed by a multi-modular matrix converter (M-MMC) with input source reactive power minimization, using predictive torque and electromagnetic flux control (PTC). This new system inherits the advantages of both multiphase machines (i.e fault tolerance and better power distribution per phase compared to three-phase machines) and those of M-MMC (i.e smaller size and weight, and no bulky storage elements). In addition, with the M-MMC topology it is possible to use two power generation sources of different characteristics instead of a single three-phase source. Results are provided for speed, torque and flux control of the SPIM and minimization of reactive power at the input source. © 2022 IEEE.

Photovoltaics (PV) play an essential role in energy networks by promoting clean, sustainable energy and reducing reliance on fossil fuels. However, their operational characteristics introduce new challenges, particularly concerning grid reliability and voltage stability. In this paper, the impact of solar photovoltaic plant (SPP) penetration on voltage behavior in the central region of Vietnam is examined using dynamic models at different integration levels, ranging from 0% to 40%. The results reveal that while low SPP penetration has minimal effects, high penetration levels (30% and 40%) significantly reduce reactive power support, exacerbating voltage collapse risks. These findings underscore the necessity for advanced voltage and reactive power control strategies to ensure grid stability in high-SPP scenarios. © 2025 IEEE.

Impact of Road Tunnel Consumption on the power Quality, power Factor and Reactive power Flow

Transportation Research Procedia 2023年 74卷 884-891页

In recent years there has been an increase in reactive power flow from lower voltage levels to higher voltage levels due to changes in the power grid. Road tunnels also contribute to the reactive power flow by their nature of loading. Tunnel consumption is mostly made up of lighting sources. Currently, the most commonly used lighting is LED-based, which includes current sources with non-linear volt-ampere characteristics and high capacitance. As a result, they draw distorted current from the grid and also generate reactive power to the grid. This paper analyzes the overall power quality based on STN EN 50 160, the total harmonic distortion of current, power factor, and reactive power of the road tunnel. The paper especially shows the effect of harmonic distortion of current on the difference between the fundamental harmonic power factor and the total power factor, and also the difference between the reactive power of the fundamental harmonic and the total reactive power.
