Special Issue Information

Dear Colleagues,

Due to the integration of renewable energy resources, the electric power system is undergoing a significant change in terms of operation and planning. The advancement into a so-called smart grid by using advanced automation and control approaches produces new challenges but also opportunities. The aim of this Special Issue is therefore to tackle the ongoing changes and innovations in the domain of power and energy systems. We invite all papers with novel contributions to smart grids and future electrical networks with, but not limited to, the following topics:

  • Advanced planning an operation concepts for power systems;
  • Sophisticated microgrid concepts;
  • Local energy communities;
  • Hybrid energy network concepts;
  • Integration of innovative power electronic devices;
  • Cyber-physical power and energy systems principles;
  • Power electronic dominated power grids;
  • Impact of new technologies (e.g., big data, IoT) on power system operation and planning.

The Impact of Virtualisation Techniques on Power System Control Networks
Electronics 2020, 9(9), 1433; https://doi.org/10.3390/electronics9091433 - 03 Sep 2020

Virtualisation is a concept successfully applied to IT systems. In this work, we analyse how virtualisation approaches, such as edge computing, brokerage and software-defined networking, can be applied in the area of electricity grid management and control systems. Power system information and communications technology is currently subject to significant changes. Networked power grid components including renewable energy units, electric vehicles and heat pumps need to be integrated into grid management systems. We studied how virtualisation techniques can support system operators in increasing an energy and communication system’s dependability and situational awareness, and how manual (mostly field-level) configuration and engineering efforts can be reduced. Starting from a working hypothesis, three concrete use-cases were implemented and the performance enhancements were benchmarked to allow for well-informed answers to the questions above. We took a close look at application-protocol-independent redundancy, grid-based routing and online system integrity control. In these study cases, we found significant improvements could be achieved with virtualisation in terms of reduced engineering effort, better system management and simplification in high-level system architecture, since implementation details are hidden by the virtualisation approach.

Electro-Mechanical Design and Creep Analysis of Proposed Enclosure for Flexible Gas Insulated Line Regarding Subsurface Metropolitan Applications of High-Voltage Transmission Lines
Electronics 2019, 8(9), 929; https://doi.org/10.3390/electronics8090929 - 25 Aug 2019

Land shortage in metropolitan vicinities entails subsurface implementation of power transmission lines (PTLs) which demand structural flexibility, as well as substantial load bearing capability. Thus, development of a flexible gas insulated transmission line (FGIL) necessitates its strength degradation analysis, regarding the synergistic effect of aging and mechanical loadings. Moreover, correlation of conductor and enclosure dimensions of FGIL apropos field distribution, requires careful consideration regarding their dimensional specifications. In this research, a comprehensive electro-mechanical design is performed for the proposed flexible-thermoplastic-enclosure of a 132 kV FGIL by considering the synergistic impact of time and temperature-based aging, along with the effect of external and internal loadings, such as dead load, live load and internal gas pressure. Additionally, a recursive design algorithm for the proposed scheme regarding electro-mechanical aspects, along with aging perspectives is developed. Comparative analysis of proposed and conventional schemes regarding electro-mechanical and aging aspects revealed that the proposed enclosure exhibits the required structural strength, as well as flexibility for trenchless subsurface application of FGILs in metropolitan areas.
