Special Issue Information

Dear Colleagues,

The change in the traditional power systems towards integrating a high level of utility-scale renewable energy sources at the transmission level and Distributed Energy Resources (DER) at the distribution level push Network Service Providers (NSPs) to research non-traditional and intelligent solutions to manage their networks. The challenges associated with the high level of inverter-based renewable energy are divided into managing an existing asset and planning for enforcing this asset for the short and long term at minimal operating costs. Focusing on the distribution side of the network, there are a number of challenges that NSPs are trying to address to be able to operate their networks with this level of complication without compromising the required level of the reliability index. The challenges are associated with maintaining acceptable network loading, voltage profile and fault levels dynamically with the change in consumer behaviour that results from the interaction of rooftop PVs, Battery Energy Storage Systems (BESS) and Electric Vehicles (EVs) with the networks.

This Special Issue aims to present and discuss the most up-to-date topics on modern distribution network operation issues and the proposed solutions. The solutions expected include the application of artificial intelligence in advance modelling techniques for load forecasting and consumer behaviours, testing intelligent demand response approaches that achieve lower operating costs for distribution networks, investigation of novel voltage control approaches for distribution networks and examination of different optimisation methods in sizing network asset.

Topics of interest for publication include, but are not limited to:

  • Advanced levels of network modelling and simulation which includes estimation of fault level and voltage profile.
  • Optimum sizing of distribution network asset for optimum planning.
  • Adaptive PVs, BESS and EVs inverters controllers for optimum voltage control at distribution networks.
  • Analysis of consumer behaviour and load forecasting modelling at the distribution networks level.
  • Demand response (Electric Vehicles, BESS and Dynamic Load).
  • Investigation of new performance standards for integrating distributed energy sources (DER) on distribution networks.
  • Distribution energy markets modelling and testing of various types of market design.

The accurate detection and identification of intermittent cable faults are helpful in improving the reliability of the distribution system. This paper proposes intermittent fault detection and identification for distribution networks based on machine-learning (ML) techniques. For this reason, the IEEE 33 bus system is simulated in the radial and mesh topologies by considering all possible single- and three-phase electrical faults and limitations to collect high-resolution voltage and current waveforms. Moreover, this simulation investigates and considers various cases including low-impedance faults (LIFs) and high-impedance faults (HIFs) with a short and long duration. The collected data from the simulation are used for high-impedance intermittent fault detection, classification, and branch identification using eight supervised learning methods. A comparison between the accuracy and error of these ML classifiers shows that gradient booster (GB) and K-nearest neighbors (KNN) have the best performance for all three objectives. However, GB has a very high computation time compared to KNN. Full article

The growing use of renewable energy sources and sustainable technologies has increased the attractiveness of low-voltage DC distribution grids. Despite initial research and standardization work, the definition of power quality (PQ) issues and their related compatibility levels in DC grids and the related measurement techniques remain in their infancy. The lack of available measurement results obtained in real-world situations is a major shortcoming. In this paper, the results of a measurement campaign obtained in a configurable bipolar 350 V/700 V DC microgrid in an urban environment are presented. Voltage and current signals were registered continuously at different positions in the microgrid with a sampling rate of 500 kSa/s while changing the configuration of the microgrid; the resulting data were analyzed afterwards, with a focus on DC voltage and current variation, ripple, and spectral analysis. The measurements were taken with custom-designed metrology-sound measurement equipment. The measurement results provide input to the development of DC PQ analysis tools and the standardization of DC PQ measurement methods. Furthermore, the experience obtained will be beneficial for utility companies and regulatory authorities for reliable planning-level and compatibility-level surveys. Full article
