Special Issue Information

Dear Colleagues,

Despite proposing new technologies in many areas, technologies known for many years are still being used. Currently designed devices that use the latest solutions can improve their energy efficiency. The topic is not only the improvement of power supply and power control systems, but also the support of energy management techniques and upgrading of existing systems.

Successful overall designs include installing a wide range of energy-saving technologies as well as adopting behavioural changes to improve energy consumption.

Electro mobility is also the development of existing vehicles, with particular emphasis on supporting disabled people. Improvements in sensor systems and control methods can increase the range and usability of such vehicles.

The use of distributed sources of renewable energy requires distributed management methods as well. In order to optimize power supply and power control systems, dedicated measuring devices supporting model-based algorithms are require.

This applies to sensory systems and model based algorithms to optimize power supply systems and power control by identifying needs and behaviours that affect energy management also machine-learning methods for accurately predicting energy consumption for optimal decision-making.

From the ecological point of view, energy saving is not only about designing new technologies, but also about applying existing material resources and devices.

The main aim of this Special Issue is to seek high-quality applications that emphasize the possibility of using the latest achievements of electronics to improve the energy efficiency of devices, systems and technologies used so far.

An important element of such an approach is taking into account the human factor and behaviours that affect the way of use and pro-ecological, holistic and social approach, based on the ideas of sustainable development, energy saving and social participation in design and operation.

The topics of interest include, but are not limited to:

  • Improvement and upgrading of power supply
  • Optimization of electric vehicle control
  • Sensory systems for energy balances
  • Implementation of numerical methods to support energy efficiency
  • Heat and mass transfer control and sensors systems
  • Predicting energy consumption
  • Smart city - electronic methods and sensors to collect data
  • Online collaborative sensor data management
  • Life cycle control of commercial products

Optimal Schedule the Operation Policy of a Pumped Energy Storage Plant Case Study Zimapán, México

Pumped-storage hydroelectric plants are an alternative to adapting the energy generation regimen to that of the demand, especially considering that the generation of intermittent clean energy provided by solar and wind power will cause greater differences between these two regimes. In this research, an optimal operation policy is determined through a simulation tool that allows the annual benefits under the energy arbitration service (purchase–sale) to be estimated, considering the variations of the energy price in Mexico. A case study is proposed in the Zimapán hydroelectric facility, where reservoir operation at the hourly level is simulated with records for a period of 3 years, considering historical values. The results establish that this type of pumped storage power plant obtains greater benefits by generating electrical energy during 8 h of high demand and pumping for more than 11 continuous hours in times of low demand. With this configuration, the PHES consumes 82.33 GWh/year more energy than it produces, and the energy generated is 210.83 GWh/year; however, when considering the energy arbitration service, a net income of more than USD 3.25 million per year is identified, which represents a 123.52% increase for the annual energy purchase.

Many electricity customers, particularly in the area of small and medium-sized enterprises, are characterized by a system of 3-phase unbalanced current consumption and the polarization of power factor in the individual phases. Strong variation of power factor in the different phases (often with both inductive and capacitive nature) causes the inability to install classic–a 3-phase reactive power compensators. Therefore, energy consumers are exposed to higher costs for the crossing of the contractual power factor. This paper describes the problem of reactive power forecasting with the use of artificial neural networks. For calculation, the Nonlinear Autoregressive (NAR) neural network was used for different input vector sizes and different numbers of neurons in the hidden layer for foreseeing reactive power generation. Results of simulations compared to real measurements confirm that it is possible to forecast the reactive power course, useful for optimal planning of reactive power compensation strategies.

The aim of this paper is to establish mathematical modelling and simulation for the voltage induced during movement of the moveable magnet in a double-sided magnetic spring, being part of the energy harvesting system. For various configurations of the set of permanent magnets, the repulsive forces of magnetic spring and induced voltage in energy harvester winding will be calculated. Changing the geometrical dimensions and shape of permanent magnets allows one to control the stiffness of the so-called double-sided magnetic spring, and furthermore, allows one to change the natural frequency of the energy harvester system. Properly chosen stiffness in the energy harvester system is the crucial issue for high efficiency in energy recovery. In a given case, the energy harvester consists of three permanent magnets inserted into a tube with coils wound on it. To calculate the force between the magnets and the magnetic flux in the coils, the ANSYS program was used. The voltages induced in coils for various configurations of the magnets were simulated in the MATLAB program. Full article

In this paper, a novel, composite material is proposed based on ferromagnetic wires immersed in a polymer that is well suited for 3D printing. The magnetic properties of this material are examined using FEM and compared with the properties of a more traditional composite based on magnetic powder. For a 50% ferromagnetic volume in the material, the proposed composite has a 67% higher value of saturation magnetic flux density and 87% higher value of maximum permeability, compared with the powder-based material. The authors believe that the proposed material could be used in the manufacturing of small electromechanical devices such as energy harvesters, thus vastly widening the possible fields of application related to 3D printing techniques.
