This paper proposed a novel isolated buck-boost dc-dc converter with wide range of voltage regulations. The proposed converter has significant features such as zero voltage switching operation, as well wide input voltage regulation range. This topology can be used in several application including Photovoltaic microconverter, when the voltage varies between 10 to 60 volts, and the output needs to be a constant dc voltage. The Buck, Buck-Boost, as well as Boost capabilities of proposed converter beside their switching states and equations of each switching states are presented. The steady state analysis is used to calculate the voltage gain for each mode. Finally, the simulation using PowerSim software is verifying the theoretical evaluation.

This paper presents a permanent magnet electrical motor prototype with an additively manufactured (AM) core, using a polymer binder based soft magnetic composite (SMC) material. The relative permeability of the electrically non-conductive SMC material was measured to be 2.4, which makes it a viable solution to be used in air-core machines. The AM prototype motor was tested under load and it generated a maximum torque of 0.31 Nm. This measured value is 30% higher than the simulated torque for an equivalent air-core machine. Therefore, the composite material can be considered a superior material in the context of ironless motors.

In this paper, isolated single-stage three-phase SEPIC differential mode inverter is presented for grid-connected applications. Grid current control is implemented by a two-loop control technique to inject pure AC current into grid and mitigate Negative Sequence Harmonic Component NSHC which is a common $2^{mathrm{n}mathrm{d}}$ order component in all differential inverter topologies. The first loop is simply validated by using a PI controller. Also, a novel feedforward control is used in the second loop instead of conventional feedback control method by detecting third-order $3^{mathrm{r}mathrm{d}}$ component in the input current of the inverter rather than direct sensing of $2^{mathrm{n}mathrm{d}}$ order NSHC from the output currents. Then, a simple PI controller is implemented to mitigate the 3rd component from input current which directly removes $2^{mathrm{n}mathrm{d}}$ NSHC from grid output current. Proposed control has higher bandwidth than traditional control method and provides pure input and output current waveforms. On other hand, simple active-clamp circuit, consisting of one switch and two small capacitors, is designed, and integrated to verify ZVS and ZCS of the main and synchronous switches of the utilized SEPIC converters which enhance the efficiency by reducing the switching losses. Moreover, the active-clamp circuit diminishes the peak voltages of the switches and enhances the reliability of the inverter. Inverter operation along with mathematical analysis of the proposed control method and soft-switching operation is presented. Finally, the theoretical assumptions are supported by simulations and experimental results.

The Four Switch Buck-Boost converter (FSBB) is a widely used topology for DC-DC applications in which isolation is not required. This is mainly due to its bidirectionality, and the ability to operate under a wide range of input and output voltages. There are several modulation strategies for this converter, each one with its strengths and weaknesses.In this paper, several modulators from state of the art are compared, and the losses of the transistors and the inductor are computed. With this information, it is intended to select the best modulator depending on the input and output voltages, output power, and hardware limitations of the designed FSBB.

In islanded microgrids (MGs), due to the low level of inertia, it is particularly important to establish a balance between the power generation and consumption at any moment. Any power imbalance in an islanded MG can increase or decrease the frequency and even cause instability. This problem has led to ever-increasing attention to energy storage systems (ESSs) to control the frequency and voltage of MGs. One of the most important ESSs in MGs is the Flywheel Energy Storage System (FESS). In this study, a cooperative control system is proposed for FESS and diesel generator emulator to control the frequency of an islanded MG. Considering a sudden load change, a new frequency distribution-based digital control system is proposed to share the required power between diesel generator and FESS. The proposed method is able to automatically assign high and low frequency terms of the mismatch power to FESS and diesel generator, respectively. To evaluate the performance of the proposed control scheme, simulation results are carried out using MATLAB/Simulink software, while a programmable load emulator is employed for dynamic load emulation. To confirm the performance of the proposed method, the simulation results are also tested with a real-time simulator.

Innovative solutions are required to sustain the balance between energy generation and demand to achieve the desired efficiency in the power system and microgrid. With the recent advances in information and communication technologies that provide energy solution services based on big data analytics, machine learning (ML), and IoT technologies, the concept of digital twins (DT) has been introduced as a constructible active model to improve the security and resiliency of the microgrid. The DT is a reliable and economic microgrid technology considering its advantages of virtual real-time simulation, physical-based control, and constant monitoring. Moreover, DTs can predict future performance, energy consumers' behaviour, and a complex system's maintenance. This paper introduces a comprehensive framework for adapting the DT into applying a microgrid that interacts with the control system to ensure its information security and proper operation. Unlike other DT frameworks in the literature, the proposed for the local energy community. The framework was tested on a distributed network system. The implementation test concluded that the TalTech DT system is applicable for developing and validating power system applications.

There is a substantial problem caused by the common-mode voltage (CMV) that is generated by PWM approaches. CMV fluctuations are responsible for the generation of harmonics with high-frequency range and leakage current flow in transformer-less photovoltaic systems. In this paper, a model predictive current control (MPCC) method employing virtual voltage vectors (VVVs) to solve aforementioned the problem in three-phase three-level neutral-point clamped (3P3L-NPC) inverters. In order to reduce CMV fluctuations, only some switching vectors are used, in which case the number of switching states is reduced and the THD of the output current of the 3P3L-NPC inverter increases. The increase in the functional area of the 3P3L-NPC inverters and the decrease in the THD of the output current has a direct relationship with the increase in the number of voltage vectors of the switching, which is realized using virtual voltage vectors. The simulation of a three-level NPC inverter is used to assess the suggested theory’s outcomes.

Electrification of residential areas is increasingly common. Major areas of development include rooftop solar panels, electric vehicles and heat pumps. However, existing grid components may have insufficient network capacity to accommodate the resulting electricity flows. Battery energy storage (BES) can be used to prevent transformer overloading resulting from electrification. Ideally, BES should be sized and placed such that it can prevent overloading with a minimum amount of storage capacity, but it is unclear how load characteristics affect BES capacity requirements. This study investigated how load simultaneity affects the minimum BES capacity required to prevent transformer overloading, comparing a central with a distributed BES layout. It was found that as simultaneity increases, distributed storage requires relatively less capacity than central storage. This is likely due to the reduced ability of central BES to share capacity between connections as simultaneity increases, and the ability of distributed BES to better reduce transportation losses.
