Special Issue Information

Dear Colleagues,

The current need to save energy and use various energy sources is causing a dynamic development of intelligent technologies in the field of energy and electrical engineering. As a result, there is a need to create a smart power grid structure with integrated communication, advanced components, advanced methods of signal processing, disturbance detection and advanced measurement technology as well as expert systems that enable automatic decision support. Smart advanced measurement infrastructure allows, among other things, the accurate and effective monitoring of power quality and system states. The need for continuous monitoring of power quality and disturbing phenomena at every point of the power grid results from, e.g., energy purchase contracts or specific legal acts. The common use of electric vehicle charging stations or power electronic devices for power conversion causes a deterioration of power quality. Considering the fact that modern equipment is sensitive to disturbances that reduce power quality, in recent years there has been a noticeable tendency for power utilities and their customers to attach much greater importance to improving power quality. Taking into account the need to maintain electricity supplies of a certain power quality, it becomes necessary to implement new smart advanced infrastructure in power grids.

“Smart Infrastructure in the Power Grids” is a Special Issue of Energies for those who would like to publish their original papers about the power quality and smart infrastructure in power grids that allows for the monitoring and improvement of power quality. This Special Issue aims to present important results of work related to power quality in the smart grid, microgrid, renewable energy, power electronics, and control techniques, the modernization of the power system, energy storage, and their various applications. The works can be applied to research, the development of new algorithms or components, original applications of existing knowledge, or new facilities applied to power systems. Prospective authors are invited to submit original papers to this Special Issue. The topics of interest for publication include but are not limited to:

  • Analysis and Modelling (Networks, Devices, Loads, etc.) of the Power Grid;
  • Deep Learning and Machine Learning Applications in Smart Grids;
  • Diagnostic Systems and Expert System Applications;
  • Impact of Distributed Generation on Power Quality;
  • Measuring and Monitoring Techniques;
  • Methods of Identification of Sources of Disturbances;
  • Power Conditioning (Active and Passive Filters, Var Compensation, UPS, Surge Protection Devices, Phase Balancing, etc.);
  • Power Quality;
  • Quality Aspects of Industrial, Commercial and Residential Consumers;
  • Smart Advanced Infrastructure (e.g., Smart Transformers);
  • Smart Energy Meters;
  • Smart Grids;
  • Standards and Recommended Practices

Various factors, particularly an increasing share in underground cable lines, can lead to excessive reactive power demand of distribution grids to their respective transport grids and, thus, to the need of costly compensation measures. At the same time, the occurrence of battery-electric cars is considerably increasing. It is, therefore, conceivable to provide reactive power as an inexpensive “waste product” by the charging converters of the cars as a solution to the aforementioned problem. In this research work, the idea is examined for its feasibility by means of extensive time series simulation using the example of a real existing distribution grid. It was found that, with a realistic number of charging points—especially public ones with integrated converter electronics—not only can the reactive power demand be reduced to an acceptable level but also additional reactive power can be provided as a service to the transport grid.
