Special Issue Information

Dear Colleagues,

Power systems is one of the major engineering accomplishments. Existing power systems as well as the smart grids utilize a number of advanced computing, networking and measurement technologies. As these technologies become more populated, power systems and smart grids are rapidly growing in scale, interconnectivity, and complexity. Driven by these facts, it is apparent that the power sector faces important operating challenges in the next years. The objective of this Special Issue is to identify, address, and disseminate state-of-the-art research focusing on recent developments and emerging trends in power systems and smart grids. Submitted works should be original research papers and reviews with a substantial novel contribution towards the scope. 

The topics covered by the issue include (but are not limited to):

  • Recent Developments and Emerging Trends in Distribution systems,
  • Recent Developments and Emerging Trends in High Voltage,
  • Recent Developments and Emerging Trends in Microgrids,
  • Recent Developments and Emerging Trends in Power system control,
  • Recent Developments and Emerging Trends in Power system monitoring,
  • Recent Developments and Emerging Trends in Power system optimization,
  • Recent Developments and Emerging Trends in Power system protection,
  • Recent Developments and Emerging Trends in Transmission systems,
  • Recent Developments and Emerging Trends in Smart grid cybersecurity,
  • Recent Developments and Emerging Trends in Smart metering,
  • Recent Developments and Emerging Trends in Synchrophasor technology

Bipolar direct current (DC) networks are emerging electrical systems used to improve the distribution capabilities of monopolar DC networks. These grids work with positive, negative, and neutral poles, and they can transport two times the power when compared to monopolar DC grids. The distinctive features of bipolar DC grids include the ability to deal with bipolar loads (loads connected between the positive and negative poles) and with unbalanced load conditions, given that the loads connected to the positive and neutral poles are not necessarily equal to the negative and neutral ones. This load imbalance deteriorates voltages when compared to positive and negative poles, and it causes additional power losses in comparison with balanced operation scenarios. This research addresses the problem of pole-swapping in bipolar DC networks using combinatorial optimization methods in order to reduce the total grid power losses and improve the voltage profiles. Bipolar DC networks with a non-solidly grounded neutral wire composed of 21 and 85 nodes are considered in the numerical validations. The implemented combinatorial methods are the Chu and Beasley genetic algorithm, the sine-cosine algorithm, and the black-hole optimization algorithm. Numerical results in both test feeders demonstrate the positive effect of optimal pole-swapping in the total final power losses and the grid voltage profiles. All simulations were run in the MATLAB programming environment using the triangular-based power flow method, which is intended for radial distribution system configurations. Full article
