Special Issue Information

Dear Colleagues,

The European Union has targeted a 55% cut in greenhouse gas emissions by 2030 towards the 2050 climate neutrality goal, and so there is an urgent need to adopt specific measures in order to pursue this objective. In this context, the inclusion of renewable energy sources plays a key role, especially the combination of them in microgrids. Microgrids enable the development of energy prosumers through hybrid renewable power generation systems, including off-grid and on-grid scenarios. Hence, the aim of this Special Issue is to cover promising, recent, and novel research trends concerning the challenges and opportunities of including renewable microgrids from the electrical point of view. Areas to be covered in this Special Topic may include, but are not limited to, the following:

  • Hybrid renewable energy systems design.
  • Energy prosumers.
  • Microgrids design and modelling.
  • Demand response in microgrids.
  • Microgrids for electric vehicles recharge.
  • Microgrids for islands electricity supply.
  • Microgrids for developing countries.
  • Economic analysis of microgrids.
  • Energy communities.
  • Storage systems in microgrids.
  • Renewable energy sources inclusion in microgrids.

This research developed smart integrated hybrid renewable systems for small energy communities and applied them to a real system to achieve energy self-sufficiency and promote sustainable decentralized energy generation. It compares stand-alone (SA) and grid-connected (GC) configurations using a developed optimized mathematical model and data-driven optimization, with economic analysis of various renewable combinations (PV, Wind, PHS, BESS, and Grid) to search for the optimal solution. Four cases were developed: two stand-alone (SA1: PV + Wind + PHS, SA2: PV + Wind + PHS + BESS) and two grid-connected (GC1: PV + PHS + Grid, GC2: Wind + PHS + Grid). GC2 shows the most economical with stable cash flow (−€123.2 annually), low CO2 costs (€367.2), and 91.7% of grid independence, requiring 125 kW of installed power. While GC options had lower initial investments (between €157k to €205k), the SA configurations provided lower levelized costs of energy (LCOE) ranging from €0.039 to €0.044/kWh. The integration of pumped hydropower storage enhances energy independence, supporting peak loads for up to two days with a storage capacity of 2.17 MWh. Full article

Electric vehicle technology is transitioning from mobility based on fossil fuel combustion to one based on vehicle electrification, in which the primary energy is increasingly renewable, and the generation of pollutants and CO2 emissions is being reduced. This paper provides a tour of the key aspects of these systems, reviewing their most important historical, legislative, and grid impact topics. For this purpose, a literature review of publications up to 2022 is conducted. The last decade is the subject of a deeper analysis, shedding light on the essential characteristics of this technology and fundamentally focusing on its integration into electrical distribution networks. This work is carried out based on a review of a selection of articles written by authors worldwide who have researched these topics. We ordered and analyzed the temporal evolution of the defined categories, obtaining their research line direction. A meta-analysis of grid impact was also carried out, prompting clear conclusions about the state of the art and potential future works. Full article
