Special Issue Information

Dear colleagues,

Sustainable Energy Systems from Multiple Sourses: a Perspective on Design, Techno-Economic Evaluation and Optimization Approaches is a continuation of the previous Special Issue, Optimal Design and Operation of Sustainable Energy Systems’. This Special Issue focuses on the technological advancement of clean and reliable energy systems for both on and off-grid applications. In recent times, renewable energy technologies, such as wind, solar, and lately, hydrokinetic energy, have increased in both installation capacity and application. The intermittent nature of these sources still poses a challenge due to their overdependence on climatic conditions.

In addition, the use of electric vehicles (EVs) is gaining momentum. If not properly managed, the uncoordinated charging of these EVs will contribute to random loads, leading to a negative impact on the operation of the existing network.

Hence, it is imperative that the design, sizing, and optimization approaches in developing such systems are made meticulously  in order to improve system reliability and efficiency.

Furthermore, the technical feasibility and economic viability of such a system need to be comprehensively evaluated for implementation, whether for on or off-grid applications. Therefore, this Special Issue considers a wide variety of areas for energy supply systems from multiple sourses, which include:

  • distributed energy resources;
  • planning and operation of energy systems;
  • standalone renewable energy systems;
  • grid integration of renewable energies;
  • techno-economic analysis of renewable energy-based systems;
  • battery storage systems in microgrid application;
  • load and renewable energy forecasting;
  • lithium–ion battery and lead acid battery modeling;
  • complex hybrid energy systems;
  • optimal design and operation;
  • smart metering and power quality;
  • active and reactive power pricing;
  • demand side management;
  • optimization under uncertainty;
  • electric vehicle.

As the global diesel generator market grows and generators gain wider use, various methods are being developed to increase their energy efficiency. One of these methods entails integrating a Li-ion battery with diesel generators (DGs). This method did not attract attention until recently because it was economically unappealing. A significant decrease in the price of Li-ion batteries in recent years has made hybrid diesel generator/Li-ion battery systems more viable. We present a model-based economic analysis of a hybrid DG/Li-ion battery system with the aim of increasing the energy efficiency of diesel power generators. Special blocks were developed for calculations and comparisons with a MATLAB Simulink model, including 457 kW DG operating modes with/without a Li-ion battery. We simulated the system in order to calculate the conditions required to achieve savings in fuel and the level of savings, in addition to the payback time of the Li-ion battery. Furthermore, we present the additional savings gained by postponing the investment in a new diesel generator thanks to the Li-ion battery. Based on our findings, the payback period of the Li-ion battery system varies between 2.5 and 4 years. According to our 12-year economic analysis, the cost savings resulting from postponing new investments can reach 40% of the profit gained from the savings during such a period. Full article
