Special Issue Information

Dear Colleagues,

The need for energy efficiency and decarbonization and the integration of storage systems and distributed generation in power systems are drawing a new route for the design and realization of energy distribution grids in the 21st century.

Power systems are becoming increasingly smart and sustainable, managed by intelligent devices allowing for the conribution of end-users in the energy share. New European regulations and support policies and the effort of major stakeholders, like ENTSO-E, are increasing due to new technologies, concepts, and devices. In this epic transformation, sustainability is one of the main keywords.

In this context, we welcome all researchers from relevant domains to submit papers to this Special Issue entitled “Power Distribution Systems and Sustainability”. Contributions on the following themes (but are not limited to) are welcome:

  • Smart distribution grids;
  • Multi-carrier energy hubs;
  • Environmental impact of modern power distribution systems;
  • Electricity from renewable energy sources;
  • Impact of battery storage systems on the generation and distribution efficiency of a microgrid;
  • Isolated power systems: design, operations, planning, economics, and efficiency improvement;
  • Impact of BAC and TBM systems on power systems;
  • Smart readiness indicator application and evaluation;
  • Smart prosumers aggregation;
  • Demand-side flexibility evaluation and exploitation;
  • Life cycle assessment of new high efficiency devices and components for power grids;
  • Algorithms for demand-side management;
  • Energy storage for mitigating the variability of renewable electricity sources; and
  • Support policies for battery storage systems.

In general, a temporary overvoltage (TOV) on the healthy phases occurs because of the neutral-shift phenomenon during a single line-to-ground (SLG) fault. The TOV can destroy the insulation of electric devices and cause damage to other equipment and customer loads in just a few cycles. In practice, the TOV can be affected by numerous factors: the sequence reactance ratio of the interconnection transformer, the ratio of load to DG, and the distance to the fault. More importantly, inverter-based distributed generations (DGs) have different influences on the TOV from traditional synchronous-machine-based DGs. In this sense, this work performed an efficient and comprehensive investigation on the effect of these various parameter types and their extensive variations, based on steady-state analysis with sequence equivalent circuits and three-dimensional representations. The proposed methodology can facilitate judging the impact of multi-parameter conditions on the TOV readily and comparing the fault characteristics of synchronous-machine-based and inverter-based DGs. Finally, the results can be used for future studies on TOV mitigation techniques. Full article

Integration of DC grids into AC networks will realize hybrid AC/DC grids, a new energetic paradigm which will become widespread in the future due to the increasing availability of DC-based generators, loads and storage systems. Furthermore, the huge connection of intermittent renewable sources to distribution grids could cause security and congestion issues affecting line behaviour and reliability performance. This paper aims to propose a planning tool for congestion forecasting and reliability assessment of overhead distribution lines. The tool inputs consist of a single line diagram of a real or synthetic grid and a set of 24-h forecasting time series concerning climatic conditions and grid resource operative profiles. The developed approach aims to avoid congestions criticalities, taking advantage of optimal active power dispatching among “congestion-nearby resources”. A case study is analysed to validate the implemented control strategy considering a modified IEEE 14-Bus System with introduction of renewables. The tool also implements reliability prediction formulas to calculate an overhead line reliability function in congested and congestions-avoided conditions. A quantitative evaluation underlines the reliability performance achievable after the congestion strategy action. Full article

Hybrid Systems in microgrid applications have gained relevance in power flow management in the context of the worldwide power grids transformation. Successfully integrating several technologies of micro resources and storage systems is a key component of microgrid applications. To address this issue, dc-bus signaling (DBS) is proposed here and used as a distributed decentralized control strategy in which the control nodes, as the generation sources/storage interface converters, induce DC bus voltage-level changes to communicate with the other control nodes. The DC bus voltage thresholds are identified and assigned to each converter to trigger the point at which it begins discharging or charging for six different DC Nano Grid (DCNG) configurations, thereby integrating both conventional and unconventional storage systems. Several test cases have been analyzed to verify the effectiveness of the proposed control logic. Full article
