A Review of the State of the Art of Industrial Microgrids Based on Renewable Energy

Abstract

Electric microgrids based mainly on renewable energies have seen a big expansion in recent years due to the great advantages they present against fossil fuels. Nowadays different governments are becoming aware of the use of environmentally friendly energies, so progressive investment has been granted to the consumers in Spain. Many microgrids have been installed in both connected and isolated circumstances, and this fact brings new challenges regarding the technical and economic points of view. This study aims to delve into electrical microgrids based on renewable energies applied in industrial facilities through a review of the literature associated with the study of general microgrids. It later focuses on the relationships between renewable energies and industrial environments. A brief reference is made to the use of energy storage systems in industrial installations depicting the most used systems. This paper presents a review of the state of the art of microgrids from distributed energy resources technologies to industrial microgrids optimization, with the primary objective of providing insight on current trends and directions in research and further identifying areas in need of further development.

Evaluación del desempeño de microrredes: una revisión

“…A pesar de la existencia de estudios sobre el desempeño de MR, algunos aspectos pueden discriminarse de forma más específica para facilitar su interpretación [4], [22]. Por ejemplo, aquellos indicadores que describen características de los elementos que suministran energía, pueden ser clasificados en la capacidad de generación; de modo similar se pueden agrupar otras métricas.…”

“…Para abordar esta brecha, el artículo propone una clasificación de métricas en capacidades como generación, operación, control, resiliencia, comunicación, mantenimiento, reconfiguración y protección. La clasificación de cada elemento facilita conocer los factores particulares de su funcionamiento y, así, analizar con mayor profundidad una determinada característica [4], [22].…”

State-of-the-art review on energy management systems, challenges and top trends of renewable energy based microgrids

“…In this way, using microgrids as a part of smart grids and creating their optimal management systems can significantly improve power grids [6]. Microgrids are controllable and consist of a set of distributed products such as wind turbines, diesel generators, fuel cells, photovoltaic systems, energy storage, and load systems, and can be used in two forms of grid connection or islanding [7]. Microgrids have advantages such as CO2 reduction and environmental benefits use as a system for the simultaneous production of electricity and heat, the production of energy needed in geographical areas far from the reach of the national grid, the reduction of fuel costs due to the use of renewable energy sources for production, and the reduction of losses.…”

Evaluation of Different Methodologies for Wave Energy Conversion Systems Integration into the Power Grid Using Power Hardware-in-Loop Emulation

“…However, this has not come without numerous challenges encompassing aspects such as power quality, stability, grid synchronization, etc. [18,19]. As the world embraces the transition toward more sustainable energy, the use of renewable energy sources continues to grow exponentially.…”
