Special Issue Information

Dear Colleagues,

The problems of energy production, the development of innovative renewable energy sources, and the optimization of energy utilization pose enormous challenges in the contemporary world. Hence, the importance of research carried out in this area.

These concerns implicate only the generation and development of renewable energy sources, but the entire sector of the efficient design of energy-saving devices, their intelligent control and use. Such problems not only affect rapidly developing electronics and electrical engineering, but also touch many aspects and fields of the modern world, such as:

  • Computer systems and their uninterruptible power supply;
  • Medicine;
  • Biomedical engineering;
  • Automotive;
  • Transport;
  • Industry;
  • Others, in which the achievements of today's electrical engineering and electronics can be applied.

In terms of the opportunity to improve the efficiency of devices, systems, control and execution systems, it is crucial that the process of reducing power losses is implemented at all possible stages, i.e. as an improvement of efficiency (reduction in energy consumption–minimization of power consumption) in low-level aspects (uP, FPGA, PLC), electronic systems (inverters, converters, power conversion systems) and renewable energy sources, describing solutions to improve the efficiency of energy conversion and acquisition.

To meet these challenges, we are publishing this Special Issue of our journal, providing a platform for researchers working in this area of science to utilize for the exchange of ideas. This will enable us to share the latest developments in the field of energy efficiency in electrical and electronic engineering.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Advances of energy efficiency in electrical engineering;
  • Advances of energy efficiency in electronics;
  • Modern control systems of power conversion systems;
  • High-efficiency power conversion system topologies;
  • Modeling and simulation of electrical engineering and electronics solutions;
  • Renewable energy systems;
  • Thermal management in terms of improving efficiency in electrical engineering and electronics solutions;
  • Minimizing power consumption;
  • Microgrids, smart grids, and distributed generation systems;
  • Energy-efficient control systems;
  • Converters for uninterruptible power supplies and motor drives.

We look forward to receiving your contributions.

Based on the characteristics of the whale optimization algorithm (WOA) and perturbation observation (P&O) method, this paper proposes a novel hybrid approach called the improved chaotic whale optimization combined with perturb and observe (ICWOA-P&O) method for maximum power point tracking (MPPT) control to solve the challenge of low efficiency in photovoltaic (PV) power generation under local shadows. First, the ICWOA is used for a global search to quickly locate the position of the maximum power point (MPP). Then, the P&O method is used for a fine-grained local search to quickly track the position of the global maximum power point (GMPP) with low oscillation. To ensure accuracy, the tracking performance of the ICWOA-P&O method is comprehensively compared with the WOA-P&O, WOA, and PSO models under four conditions: uniform irradiance, static local shading, dynamic shading, and sudden changes in irradiance and temperature. The simulation results verify that under the above four conditions, the ICWOA-P&O method can track the MPP continuously and stably and greatly improves the convergence time and accuracy. Compared with the other three methods, the ICWOA-P&O method can effectively obtain the fastest tracking speed (less than 0.1 s), the highest tracking accuracy (more than 99.97%), the smallest relative error (less than 0.03%), and the smallest oscillation fluctuation. Finally, this study integrated the ICWOA-P&O algorithm into the designed MPPT controller hardware and established a practical PV experimental platform based on the ICWOA-P&O control algorithm for practical tests.

The purpose of the paper is to propose a new implementation of the PID (proportional–integral–derivative) algorithm in digital hardware. The proposed structure is optimized for cost. It follows a serialized, rather than parallel, scheme. It uses only one arithmetic block, performing the multiply-and-add operation. The calculations are carried out in a sequentially cyclic manner. The proposed circuit operates on standard single-precision (32-bit) floating-point numbers. It implements an extended PID formula, containing a non-ideal derivative component, and weighting coefficients, which enable reducing the influence of setpoint changes in the proportional and derivative components. The circuit was implemented in a Cyclone V FPGA (Field-Programmable Gate Array) device from Intel, Santa Clara, CA, USA. The proper operation of the circuit was verified in a simulation. For the specific implementation, which is reported in the paper, the sampling period of 516 ns was obtained, which means that the proposed solution is comparable in terms of speed with other hardware implementations of the PID algorithm operating on single-precision floating-point numbers. However, the presented solution is much more efficient in terms of cost. It uses 1173 LUT (Look-up Table) blocks, 1026 registers, and 1 DSP (Digital Signal Processing) block, i.e., about 30% of logic resources required by comparable solutions. Full article

The paper presents a practical methodology for the prediction of power consumption of a multitask real-time system. The authors briefly recall the structure of the original multitasking time-predictable system. The system has a regular and scalable architecture. It consists of many cores based on pipeline processing with threads’ interleaving mechanism. In previous works, the authors have presented a number of issues related to the methodology of designing a time-predictable system and the scheduling of hardware threads with different design goals and constraints. The current article presents an accurate method for measuring the dynamic power dissipated in a system for various scenarios and the system configuration. The proposed approach is based on continuous monitoring of the power consumed by the FPGA, transmitting the measurements to the computer from the measuring device, and online analysis of the obtained results. The authors based their power estimation method on the original task frequency factor (TF). A theoretical analysis was made, and a series of practical experiments were carried out. The results obtained enable accurate estimation of the power requirements for the tasks performed in the real-time system. The presented technique can be useful during the design stage of multitasking real-time systems. Full article

This paper uses colored Petri nets (PN) to develop a model of vehicle movement in a city. The modeler defines the number and location of crossroads, the connections between them, and how many vehicles are at the given points of the network. The vehicles are recognized by their license plate numbers, and it is possible to determine where they start their journey and where they are going. The algorithm proposed in this paper suggests the shortest vehicle route based on Dijkstra’s algorithm. This study focuses on improving route planning by considering road usage, which is determined by the starting and ending locations of vehicles (as if traffic cameras were identifying license plates). This approach will lead to optimal control of traffic lights (or vehicle navigation) to minimize traffic jams and make good use of all roads. Additionally, this paper shares the results of preliminary simulations using both colored and uncolored Petri nets in the GPenSIM environment. Full article
