The article presents a modulation method for BLDC motors with unconnected windings. This method uses two full bridges (or three 12-switch H-bridges). The use of the described modulation enables reducing the motor current variable and increasing (fourfold in relation to the switching frequency) the motor current ripple frequency. The most important benefit of using a 12-switch inverter is the twofold reduction of the dc-link voltage while maintaining the rated rpm (voltage reduction in comparison to a typical supply method). A voltage reduction causes a reduction in losses on semi-conductor elements. The article also demonstrates that the proposed modulation technique significantly shortens the time of current commutation between windings.

The Convolutional Neural Network (CNN) model is one of the most effective models for load forecasting with hyperparameters which can be used not only to determine the CNN structure and but also to train the CNN model. This paper proposes a framework for Grid Search hyperparameters of the CNN model. In a training process, the optimal models will specify conditions that satisfy requirement for minimum of accuracy scores of Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE) and Mean Absolute Error (MAE). In the testing process, these optimal models will be used to evaluate the results along with all other ones. The results indicated that the optimal models have accuracy scores near the minimum values. Load demand data of Queensland (Australia) and Ho Chi Minh City (Vietnam) were utilized to verify the accuracy and reliability of the Grid Search framework.

For voltage-source-converter based high-voltage-direct-current (VSC-HVDC) transmission systems, fault ride-through (FRT) capability is a very important grid requirement in order to enhance its operational availability under an alternating current (AC) grid fault condition. Voltage sags during a short-circuit fault in power transmission lines can lead to fluctuations in the direct current (DC) link voltage of converter systems, and may induce reversed power flow and even trip a VSC-HVDC transmission system. A practical method is developed in this paper for investigating FRT capability of VSC-HVDC transmission system characteristics during a voltage sag event using experimental results from Smart Grid Laboratory. Symmetrical and asymmetrical voltage sag events with different remaining voltages are applied to an AC grid that lasts with a variable duration. The experimental waveforms of the two converter systems are recorded and analyzed in order to evaluate the FRT capability of VSC-HVDC transmission systems.

Wind power integration through the voltage source converter-based high-voltage direct current (VSC-HVDC) system will be a potential solution for delivering large-scale wind power to the “Three-North Regions” of China. However, the interaction between the doubly-fed induction generator (DFIG) and VSC-HVDC system may cause the risk of subsynchronous oscillation (SSO). This paper establishes a small-signal model of the VSC based multi-terminal direct current (VSC-MTDC) system with new energy access for the problem, and the influencing factors causing SSO are analyzed based on the eigenvalue analysis method. The theoretical analysis results show that the SSO in the system is related to the wind farm operating conditions, the rotor-side controller (RSC) of the DFIG and the interaction of the controller in the VSC-MTDC system. Then, the phase lag characteristic is obtained based on the signal test method, and a multi-channel variable-parameter subsynchronous damping controller (SSDC) is designed via selecting reasonable parameters. Finally, the correctness of the theoretical analysis and the effectiveness of the multi-channel variable-parameter SSDC are verified based on time-domain simulation.

Multilevel inverters have been widely used in various occasions due to their advantages such as lowharmonic content of the outputwaveform. However, because multilevel inverters use a large number of devices, the possibility of circuit failure is also higher than that of traditional inverters. A T-type three-level inverter is taken as the research object, and a diagnostic study is performed on the open-circuit fault of insulated gate bipolar transistor (IGBT) devices in the inverter. Firstly, the change of the current path in the inverter when an open-circuit fault of the device occurred, and the effect on the circuit switching states and the bridge voltages were analyzed. Then comprehensively considered the bridge voltages, and proposed a fault diagnosis method for a T-type three-level inverter based on specific fault diagnosis signals. Finally, the simulation verification was performed. The simulation results prove that the proposed method can accurately locate the open-circuit fault of the inverter device, and has the advantage of being easy to implement.

Mathematical models of electric an arc with disturbed geometric sizes were created based on initial assumptions adopted from theMayr and Cassie models. Two cases of approximation of arc characteristics were considered separately. The Mayr–Voronin model was created in the low-current range with an exponential dependence of conductance on plasma enthalpy. However, the Cassie–Voronin model created is valid in the high-current range with a linear dependence of conductance on plasma enthalpy. In addition, the effect of two different assumptions about the method of energy dissipation, proportional to the lateral surface of the column or proportional to the volume of the column, on the parameters of both mathematical models was compared. It has been shown that under constant geometrical parameter values, created models can be reduced to classic Mayr and Cassie models. Then, these modelswere modified by taking into account the additional increase in heat dissipation as the current increases. Increasing voltage and current characteristics correspond to such an arc. Using the computer simulations, the effectiveness of using developed mathematical models in mapping the dynamic characteristics of the electric arc has been shown.

The comprehensive evaluation of the smart grid is of great significance to the development of the power grid. This study mainly analyzed the coordinated planning of major networks and power distribution networks of the grid. Firstly, the coordinated planning of major networks and power distribution networks was introduced, then a comprehensive evaluation index system was established based on six domains, i.e., economy, safety, reliability, coordination, environmental protection, and automation. The evaluation of the indexes was realized through the expert scoring method. Finally, taking the power grid planning of Boao Town, Qionghai City, Hainan Province, China, as an example, the current scheme and planning scheme were evaluated. The results showed that the planning scheme had better performance in aspects such as economy and reliability, and its score was 15.39% higher than the current scheme, which verifies the effectiveness of the planning scheme and its feasible application in practical projects.

This paper established a radio-frequency electrode model and human head model used in RF cosmetic instruments. The distribution of electric field strength, a specific absorption rate (SAR), and temperature distribution in the human brain at 1 MHz and 6 MHz were studied and the results compared with the International Commission on Nonionizing Radiation Protection (ICNIRP) guidelines. The results showed that under those two frequencies the maximum value of electric field strength in the human brain was 1.52 V/m and it was about 5.4% of the ICNIRP basic restrictions, the maximum SAR in human brain was about 2:21 ? 10??3 W/kg, which was far less than 2 W/kg of ICNIRP basic restrictions, the maximum temperature of the human brainwas 37:6? located in thewounded skin, which was the same as the normal temperature 37?. Since all the results were within the ICNIRP basic restrictions, the electromagnetic exposure generated by the RF cosmetic electrode will not pose a threat to the human health.

With the development of wireless power transfer technology, more and more attention has been paid to its electromagnetic safety. In this paper, a novel hybrid shielding structure composed of the innermost fan-shaped ferrite, the interlayer nanocrystalline strip and the outermost aluminum foil is proposed to shield the electromagnetic field of the inductive power transfer system. Eight structure parameters of the proposed shielding are optimized by finite element simulation, in order to reduce the magnetic leakage of the system and improve the utilization rate of shielding materials. In addition, the proposed structure is compared with two types of typical double-layer hybrid shielding from the perspectives of the weight, the coupling coefficient and the magnetic flux leakage. Both simulation and experiment results show that the cost and weight of the proposed shield are about 60% lower than the traditional disk shield. Moreover, the shielding layer proposed in this paper can not only effectively reduce the magnetic flux leakage of the system, but also maintain a high coupling coefficient.

In the asynchronous interconnected power grid that is composed of the multiterminal voltage-source converter high voltage direct current (VSC-MTDC) system, the control methods of each converter station and the frequency of the connected AC system are not the same. When a fault occurs in any place of the asynchronous interconnected system, it will cause the system to have power shortage or surplus, affecting the safe and stable operation of the interconnected power grid. In order to solve the problem of insufficient regional active power reserve, based on the VSC-MTDC asynchronous regional interconnection system and the principle of regional sharing, the dynamic power controller under disturbance conditions is established, and the controller parameters are set to achieve the accuracy of unbalanced power in the disturbance area measuring. Then, according to the degree of the disturbance power, considering the factors that affect the support effect of the converter station, an emergency DC power support (EDCPS) scheme under different power disturbances is formulated to achieve power compensation for the disturbance area. Based on PSCAD/EMTDC software, the proposed control strategy is simulated. The result shows that the converter station closer to the disturbance area has a better support effect, and the dynamic active power controller can timely and accurately deliver to the disturbance area when the active power reserve is insufficient.

This paper presents the application of Flexible Alternating Current Transmission System (FACTS) devices based on heuristic algorithms in power systems. The work proposes the Autonomous Groups Particle Swarm Optimization (AGPSO) approach for the optimal placement and sizing of the Static Var Compensator (SVC) to minimize the total active power losses in transmission lines. A comparative study is conducted with other heuristic optimization algorithms such as Particle Swarm Optimization (PSO), Timevarying Acceleration Coefficients PSO (TACPSO), Improved PSO (IPSO), Modified PSO (MPSO), and Moth-Flam Optimization (MFO) algorithms to confirm the efficacy of the proposed algorithm. Computer simulations have been carried out on MATLAB with the MATPOWER additional package to evaluate the performance of the AGPSO algorithm on the IEEE 14 and 30 bus systems. The simulation results show that the proposed algorithm offers the best performance among all algorithms with the lowest active power losses and the highest convergence rate.

This paper proposes an advanced Internet of Things (IoT) system for measuring, monitoring, and recording some power quality (PQ) parameters. The proposed system is designed and developed for both hardware and software. For the hardware unit, three PZEM-004T modules with non-invasive current transformer (CT) sensors are used to measure the PQ parameters and an Arduino WeMos D1 R1 ESP8266 microcontroller is used to receive data from the sensors and send this data to the server via the internet. For the software unit, an algorithm using Matlab software is developed to send measurement data to the ThingSpeak cloud. The proposed system can monitor and analyse the PQ parameters including frequency, root mean square (RMS) voltage, RMS current, active power, and the power factor of a low-voltage load in real-time. These PQ parameters can be stored on the ThingSpeak cloud during the monitoring period; hence the standard deviation in statistics of the voltage and frequency is applied to analyse and evaluate PQ at the monitoring point. The experimental tests are carried out on low-voltage networks 380/220 V. The obtained results show that the proposed system can be usefully applied for monitoring and analysing chosen PQ parameters in micro-grid solutions.

The neutral point clamped (NPC) three-level inverter is widely used in highvoltage and high-power applications. However, neutral point voltage oscillation (NPVO) and common-mode voltage (CMV) problems exist in the NPC three-level inverter. In this paper, an improved virtual space vector modulation (VSVM) is proposed based on the reconstruction of a virtual small vector and a virtual medium vector. Compared with the traditional VSVM, an improved VSVM can effectively reduce the CMV. On this basis, a vector conversion method is proposed to further reduce the NPVO in the whole range. Simulation results verify the effectiveness and superiority of the improved VSVM.

The energy storage system (ESS) is an important way to improve the power quality of renewable energy sources (such as solar energy and wind energy). A bi-directional DC/DC converter is an essential part of the ESS to achieve bi-directional energy transfer. According to the characteristics of the low-voltage gain and high-voltage stress of switches in the existing bi-directional DC/DC converter, this study proposes a novel two-phase interleaved parallel bi-directional DC/DC converter. The converter can effectively combine the advantages of a Z-source network and interleaved parallel structure. The working principle, the boost mode and buck mode of the converter are analyzed in detail. In addition, the voltage conversion ratios under the two modes are deduced. The control strategy of the two-phase interleaved parallel bi-directional DC/DC converter is introduced in detail. Furthermore, the main working waveforms of the system under each working mode are verified by building a simulation experiment model using MATLAB/Simulink. The simulation results show that the system has advantages of high-voltage gain, low-voltage stress of switches and automatic current sharing between inductors.

Varying ohmic loss in the winding of electrical machines, which are operated at various operating points, results in temperature changes during operation. Particularly, when the temperature is varying dynamically, the insulation system suffers from repeated thermalmechanical stress, since the thermal expansion coefficients of the insulating materials and copper conductors are different. For the appropriate design of an insulation system, the effect of thermal-mechanical stress must be known. In the present work, motorettes are subjected to repeated thermal cycles. The expected lifetime is estimated and compared to the lifetime which is achieved by applying a lifetime-model which only considers thermal aging while ignoring thermal-mechanical stress effects. In addition, the hotspot temperature is simulated, the lifetime at the hotspot is estimated as theworst case. As expected, the results indicate that the thermal-mechanical stress plays a significant role during dynamic thermal aging of the winding insulation system. To better understand the thermal-mechanical stress effect, the resulting thermal-mechanical stress in a single wire is analyzed by the finite element method. A preliminary analysis of the aging mechanism of materials due to cyclic thermal-mechanical stress is performed with the theory of material fatigue.

All manuscripts should be submitted electronically on Editorial System.

Submission of paper to the Archives of Electrical Engineering is understood to imply that the article is original, unpublished and is not being considered for publication elsewhere. All articles will be reviewed. Since 2013, Authors wishing to use the facility of colour printing should consult the editors.


Microsoft Word is recommended as a standard word processor to prepare the paper to the AEE journal. If you use the LaTex format, please transfer your document to Microsoft Word and then use Template AEE.

While editing your paper, make sure that all the mathematical characters (symbols, identifiers, variables, vectors, axis marks, etc.) have the required shape, thickness, and slant kept throughout the whole article. The same appearance of a given mathematic character must be retained regardless of its place (text, equations, tables or figures).

The articles that don’t conform to the above will not be processed and published.

The reviewing process:

Each paper submitted for publication in Archives of Electrical Engineering is subjected to the following review procedure:

a) the paper is reviewed by the editor in chief or guest editor for general suitability for publication in AEE

b) if it is judged suitable two reviewers are selected and a double blind peer review process takes place

c) based on the recommendations of the reviewers, the editor then decides whether the paper should be accepted in its present form, revised or rejected

d) the author(s) is(are) informed by e-mail on the results of the reviewing procedure.

The papers are published on average within 3 months after acceptance.

Requirements for preparation of manuscripts:

The manuscript submitted for publication should have no less than 12 pages and no more than 16 pages. In the case of the manuscript longer than 16 pages, please contact the AEE Editorial Board before submitting your paper. The manuscripts, written in UK English, should be typed using Template AEE according to the following instructions and should include: a title page with the title of a manuscript, a short title; abstract; key words, text; list of references. A DOI number as well as received and revised data will be completed by Editor. When you open Template.doc, select "Print Layout" from the "View" menu in the menu bar (View > Print Layout). Then type over sections of Template.doc or cut and paste from another document and then use markup styles (Home > Styles). For example, the style at this point in the document is "main text").

All papers submitted for publication are assessed on the basis of the mutual anonymity rule as to the names of reviewers and authors. Authors' names and affiliations should not appear in the attached text/tables/figures.

If English is not your first language, ask an English-speaking colleague to proofread your manuscript. The manuscripts that fail to meet basic standards of literacy are likely to be immediately declined or after the language assessment, sent to the authors for linguistic improvement.

The manuscripts are published on average within 3 months after their acceptance.

Do not change the font sizes or line spacing to squeeze more text into a limited number of pages. Leave some open space around your figures.

The AEE journal publishes an ORCID for all authors. You will need a registered ORCID in order to submit your paper for peer review. ORCID registration is free and only takes a minute. Please note that ORCIDs will be added in the course of the author's proofreads.


The pages must be numbered consecutively. Articles should be divided into numbered sections, and if necessary subsections, preferably: Introduction, Material, Methods, Results, Conclusion and References. Any special characters (e.g. Greek, script, etc.) should be named in the margin where the character first occurs in the text. Names of species are to be accentuated with wavy underlining (italics). Equations should be numbered serially (1), (2), ... on the right side of the page. Footnotes should be avoided, if required, they should be used only for brief notes which do not fit well into the text. Figures and tables have to be included into the text. If table is typed on a separate page its position in the text should be marked. Abbreviations should be explained when they first appear in the text.


Please use the MathML editor as well as MathType editor to build an equation in your manuscript.


Equations should be typed within the text, centred, and should be numbered consecutively throughout the text. Their numbers should be typed in parentheses, flush right. Equations should be referred to in text, e.g. (1), except at the beginning of a sentence: "Equation (1) is ...". All symbols appearing in equations have to be defined in the text, before or just after the equation.

If the symbols are written in Times New Roman use italic fonts. Symbols of vectors and matrices should be written in bold fonts. Do not italicize Greek fonts and mathematical symbols like e.g.: the derivative symbol d, max, min, etc. The indices of symbols that are indices themselves should be written in a clear manner.

Note that the equation is centered using a center tab stop. Please keep the same font in the formulas and text.

Unit Symbols, Abbreviations:

Define abbreviations and acronyms the first time they are used in the text, even after they have been defined in the abstract. Abbreviations such as IEEE, SI, MKS, CGS, sc, dc, and rms do not have to be defined. Do not use abbreviations in the title or heads unless they are unavoidable.

Si units are recommended for use in formulas, drawings and tables., for example the SI unit for magnetic field strength H is A/m. Apply the center dot to separate compound units.

Do not mix complete spellings and abbreviations of units: "Wb/m2" or "webers per square meter," not "webers/m2." Spell units when they appear in text: "...a few henries…", not "...a few H…".

Use a zero before decimal points: "0.25," not ".25." Use "cm3," not "cc."

Unit Symbols, SI Prefixes as well as Abbreviations should be writing in accordance with the IEEE standard

Tables, figures (illustrations) and captions:

The illustrations (line diagrams and photographs) should be suitable for direct reproduction. The lettering as well the details should have proportional dimensions to maintain their legibility after the usual reduction. All illustrations should be numbered consecutively (Fig. X). Tables are numbered with Arabic numerals.

All figures, figure captions, and tables in the text must be inserted into the correct places.

Figures, photos, tables or other parts of a manuscript that have previously appeared in another publication or are not the property of the authors must be properly acknowledged in the manuscript. Permission to republish these items must be obtained by the corresponding author from a person or institution holding the copyright, usually the publisher.
