Special Issue Information

Dear Colleagues,

As the environmental impacts of fossil fuels have become more apparent over time, the need for sustainable energy provision will become increasingly critical on a worldwide scale over the next years. Distributed electricity generation based on renewable energy technologies (solar, wind, hydro, etc.,) is becoming a more important energy option in future generation systems. In addition to the advantages of clean energy sources and limitless capacity, distributed generation and renewable energy sources still have certain drawbacks, such as high costs, unpredictability (highly reliant on weather conditions), a threat to the stability and reliability of the power system, etc. Therefore, research and industry are collaborating to overcome technical and socio-economic difficulties in support of a future with decarbonized power to further enhance the capabilities of renewable energy and the benefits it provides to communities.

This Special Issue aims to present and disseminate the most recent advances related to renewable energy sources and distributed generation.

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

1) System Studies

  • Renewable energy systems and sources (RESSs) as wind energy, solar energy, wave energy, tidal energy, hydrogen and fuel cells;
  • Energy storage system for RESSs;
  • Integrated renewable energy system;
  • RESSs for electrical vehicles and components;
  • Microgrid/Smart grids and RESSs;
  • Energy management system, VPP (Virtual Power Plant) for RESSs.

2) Modeling, Analysis, and Control

  • Modeling and simulation techniques for renewable energy systems (RESs);
  • Control techniques for RESs;
  • Performance analysis of RESs.

3) Grid Integration and Optimal Operation

  • Grid integration studies for RESs and distributed generation;
  • Decision support systems for RESSs;
  • Reliability and maintenance in RESSs;
  • Artificial intelligence and machine learning studies for RESs and applications;
  • Digital twin for RESSs;
  • Output power forecasting for RESs.

Faults in wind turbine rotating components contribute significantly to malfunctions and downtime. A prevalent strategy to reduce the Cost of Energy (CoE) in wind energy production focuses on minimizing maintenance expenses associated with these turbine components. An accurate Remaining Useful Life (RUL) diagnosis of these components is crucial for maintenance planning, ensuring uninterrupted energy quality and cost-efficiency. This paper introduces a refined method for RUL prediction of wind turbine rotating components using a Health Index (HI) derived from vibration signals. Performing HI construction by extracting all features from the vibration signal and selecting the best features to build HIs using on Principal Component Analysis (PCA) and some abnormal areas that deviate from the bearing damage trend can be eliminated. After constructing a HI use the similarity model and degradation models to predict RUL. Research results show that this degradation method can provide a reliable means to predict the RUL of wind turbine rotating components based on vibration signals. More importantly, predicting RUL in this way can significantly reduce operating and maintenance costs by providing wind turbine rotating operators with sufficient advance notice to plan repairs or replacements before any component failure occurs.

The increasing penetration of Distributed Energy Resources (DERs) in Distribution Systems (DSs) has motivated studies on Virtual Power Plants (VPPs). However, few studies have jointly assessed the sizing and economic attractiveness of VPPs from the entrepreneur’s perspective and the potential benefits and impacts on power systems while maintaining the scope to DSs. This study proposes a methodology for sizing VPPs and simulating their economic optimal dispatch and economic attractiveness with a focus on the entrepreneur’s viewpoint. In addition, it also evaluates VPPs’ potential benefits and impacts on a DS or Transmission System (TS) while considering the interface between the Distribution System Operator (DSO) and the Transmission System Operator (TSO). The methodology employs optimization to minimize the Net Present Cost (NPC) of the project, in relation to sizing the DERs, and to obtain the economic optimal dispatch of the BESSs that comprise the VPP. Moreover, a power flow analysis and probabilistic reliability assessment are used to evaluate the benefits and impacts on the power system. The methodology was applied to a case study involving Photovoltaic (PV) systems and Battery Energy Storage Systems (BESSs) used by aggregated medium voltage consumers, which configure Technical Virtual Power Plants (TVPPs) participating in Demand Response (DR) via incentives, with a network model of the Brazilian National Interconnected System (SIN) adapted from the 2030 Ten-Year Energy Expansion Plan (PDE) of the Energy Research Office (EPE), along with data from the Geographic Database of the Distribution Utility (BDGD). The results indicate the economic attractiveness of DERs according to the premises adopted and indicate improvements in TS reliability indexes with the possibility of TVPPs’ dispatch after transmission contingencies.
