Special Issue Information

Dear Colleagues,

All homes and industrial sectors require energy, making it an important and essential aspect of human existence.

Power demand has increased dramatically in recent decades due to population growth. The introduction of new technologies has altered the generation, transmission, distribution and utilization of electrical energy, and the energy landscape is evolving toward more adaptable and sustainable energy systems. Electricity outages are a serious issue today, and they occur because of the large amount of power wasted in various sectors.

One of the most significant criteria in modern applications is the deployment of energy-efficient systems. The goal of these systems is to control energy consumption while reducing environmental impact, through the efficient management of existing renewable and non-renewable resources.

The progress of electronics and informatics, as well as improvements in users’ experiences (in home, building and industrial applications), has resulted in the design and production of high-performance microcontrollers and PLCs, to which many peripherals can be linked with other equipment. On the subject of energy, microcontroller systems and PLCs exhibit extraordinary dynamics, with many applications in different areas of energy.

This Special Issue of Energies, “Microcontrollers Systems and PLCs Used in Energies”, aims to publish outstanding papers on microcontroller systems and PLCs, with topics including:

  • Energy monitoring;
  • Energy efficiency;
  • Smart energy meters;
  • Electrical power quality;
  • Automation in transport and distribution in power systems;
  • Smart protection in power generation and utilization;
  • Renewable energy systems (solar, wind and fuel cells);
  • IoT in power engineering.

There are numerous engineering solutions available using microcontroller systems and PLCs in: energy monitoring; saving energy in home, building and industrial applications; smart energy meters; power quality; smart protection applications; automation in power engineering; renewable energy systems; and IoT applications in power engineering. Author submissions should present different problems and solutions (through modelling, simulations and experiments) in these areas and provide brief explanations of their solutions, with the inclusion of comparative studies.

In power engineering, the importance of maintaining a high power factor in low-voltage electrical installations is known. In power substations for industry, the usual method of coupling is to use an automatic power factor controller which connects capacitors banks (with electromagnetic contactors). Sometimes, AC reactors are connected to the phases of the capacitors banks (to reduce transient phenomena and the deforming regime), depending on the desired value of the power factor. This paper presents an analysis (more focused on experimentation) of a low-cost system for automatic regulation of the power factor with a reduction in transients and an increase in the life of contactors (eliminating the electric arc during switching on), with capacitors banks for low-voltage three-phase installations that connect the capacitors banks by means of one three-phase solid-state relay (an expensive device for a quality device; one is used for all capacitors banks) and using several electromagnetic contactors. The automatic power factor adjustment system has a controller with a microprocessor with six outputs, controlled by the phase shift between the current (measured with a current transformer proportional to the current in a bar) and the phase voltage, which is part of a system of distribution bars (L1,2,3, N) from which electrical consumers (e.g., induction motors) are supplied. To reduce transients when connecting capacitors banks, a three-phase solid-state relay and two related electromagnetic contactors are used for each capacitors bank. The automatic power factor controller is connected to two low-capacity PLCs that control the logic of connecting the capacitors banks to reduce transients. By using the proposed regulation system, a cheaper control solution is obtained compared to the use of one solid-state relay for each capacitors banks, under the conditions in which the power factor adjustment is made as in the classic solution. If twelve capacitors banks are used, the proposed installation is 22.57% cheaper than the classical power factor regulation installation. Full article
